Hi Everyone!

With Cannabis legalization coming in a few days here in Canuckistan, I wanted to get started with my own home grown.

I've got a 40 Gallon standard aquarium, with hood and light. I'm looking to hopefully repurpose these into my grow spot.

Looking for ideas on how to set it up. what sort of light I should try and find for it (Currently has a UVB from previous occupant), what sort of seeds to grow (Drawf? Something that will remain in this aquarium till harvest with ok yeilds (Winter is coming, outdoors will be next year).

if it's legal why the fuck would you grow inside of a tiny box? It will come out small and shitty. If you want good weed you need a bright light. Get one of these cheap chinese LED arrays and give it an entire closet. I got one that works like a charm.
https://www.ebay.com/itm/MUCH-300W-LED-Grow-Light-Hydro-Full-Spectrum-Veg-Flower-Indoor-Plant-Lamp-Panel/142959170940?epid=2215360137&hash=item214907d57c:g:YYQAAOSwwB5bqsYm:rk:7:pf:0

The more light the danker your weed will be. You'd be better off just putting it outside if you're going to use a weak shitty light. Spectrum is important, any old light won't work nearly as well and will be highly inefficient compared to a light with a custom spectrum designed for growing plants.

Thanks for the reply.

  1. "Tiny Box" because of limited space indoors. Trying to maximize the existing spaces and tools I may already have at hand. If using an Aquarium is so ridiculous an idea, than so be it, I Am not apposed to anything else.

I Understand what you mean entirely by light. If Full spectrum UVB isn't enough and one of those light "pods" are recommended, i'm willing to buy. You say the one you linked as "Cheap Chinese" though. What's the lifespan on these? Would buying a better quality one be worth while? I'm a cheap ass, but I hope to have whatever setup usable year round for a few years.

now if the aquarium thing just is a no go, Than i'd need other options for a fairly contained grow enclosure. I have pets, so having it in an enclosure is a must to keep them out (They can't get into the Aquarium i've got as an example).

New to the grow scene. if it weren't for winter, i'd be doing this outdoors for my first grow (since I've got garden space)

Unfortunately I have no idea what the longevity of any given light you purchase will be. I bought my light off ebay a few years back and it looks almost exactly the same and it worked well but I've only used it for one grow so far. They seem to be pretty simple devices for the most part though, just some LEDs and a couple of computer fans in a case to keep things cool. Even if a few LEDs crap out on you, the rest should work just fine.

As far as needing an enclosed space goes, you certainly can grow in a 40 gallon aquarium but it won't be ideal for several reasons, first off, it's just too small. Remember you need to grow the plant in something, so you'll need a pot of some kind, that leaves you with very little vertical room for the plant itself. Marijuana plants stretch upwards vertically during the first few weeks of flowering and usually double or even triple in height, so even if you start flowing with a tiny plant, you will run out of vertical room. You will also need good air flow which means you will need to put a fan in the aquarium further reducing your space for the plant. You're going to take a minimum of 2 months to grow even the fastest flowering strains but a plant that fits in a container that size won't produce more than an ounce tops and that's with lots of work to manage the canopy. As a rookie in a space that small you're likely to get almost nothing for your efforts. Simply growing in a larger space will make the wait more worth it because you get more bud.

Another reason it's not ideal is because the clear sides will let out all your light. Ideally the sides of your grow chamber should be an extremely low gloss (matte/flat) white paint with high reflectivity because white paint reflects all spectra of light. Most ceiling paint fits the bill. Specially designed reflective materials like mylar will also work. If you're planning to use the light in the aquarium I doubt it will be powerful enough to grow good weed, and when it comes to spectrum it's not a matter of whether you have enough of the spectrum, but rather whether it's optimized for plant growth. Weed needs mostly blue and red light with smaller amounts of UV being beneficial but not essential. A full spectrum light might be producing most of its light in a range not utilized well by cannabis which is why people who grow under lights not designed to grow plants often have terrible results.

Really light is the most important factor imo. People buy expensive nutrients and put it under a shitty light and it ends up dying or barely giving them a couple grams of larfy nugs. They should do the opposite and just grow some weed in cheap potting soil with cheap and weak nutrients (most people put waaay too many nutrients their first time and burn the plant) and buy more powerful lights. LEDs are the most efficient, so they cost the least in electricity to run, they're the most durable, and they run cooler than most other options and prices have come down a lot in recent years so I recommend them.

I'd suggest you find a space with at least 3 feet of vertical space as an absolute minimum with more being preferable. Anything will work but a small closet is my preferred area because it's easy to paint white and the shelves at the top can be used to hang the lights from. It's also easy to cut a hole in the ceiling of a closet where it won't be noticed to run ducts with a fan blowing into a carbon filter to contain smell and ventilate the area, but if it's legal where you live then you probably won't even need that. You could also build or buy a grow tent rather than use a cabinet or a closet or something. Get a fan, a more powerful light, some nutrients (but go easy on them, especially at first), a bigger space, some potting soil and maybe mix in a little perlite or vermiculite and you'll be good to grow some great weed.

hey folks my cannaplants are looking good but they seem to be making pop corn buds (the bud sites are small little clumps but it fails to grow as a thingy properly) its purpleing around the top of the cola its an unidentified strain from street acquired seeds so im not sure if thats natural for it, personally i suspect it just to be cold stress. it had some mild root rot that ive fixed and its in a small pot. by it i mean the crop. basically theyre doin good but they smell like faint flowers. i havent grown successfully before so i could imagine frying it and getting the water weight out would make the smell less diluted but idk. ipleae let me know what might be up cause im lost here man

I've been exploring different paths for my life, and one of my ideas is that when I finish up my Air Force enlistment in 2 years, I want to back to my home state of Colorado and start growing weed in the hopes of starting a recreational marijuana business with some friends of mine. I've pirated a couple of basic botany/horticulture books and some marijuana growing books as well and have started reading up on them, but I know the best way to get good at something is by doing it.

Unfortunately, I am stationed in Oklahoma, where marijuana isn't completely legal. My question is: What is the closest plant I can grow that's most similar to marijuana as far as the growing process goes? Should I just learn to grow random foods like tomatoes and shit? I just want to know what would have the most carryover knowledge-wise.

Also, since medical marijuana laws have relaxed a bit in Oklahoma, I was considering contacting any local dispensaries near me and asking if their grower would consider the possibility of an apprenticeship with them, even if it's just doing shitty grunt work/manual labor and only learning a few small things as I go. Is it unrealistic to expect a yes? Like would that be weird or is there a better way to go about it?

hops would be a good guess, but if you want to show off your growing skills just do something showy and post pictures of it to IG until you become a reputed horticultural expert. epcot tomato tree is a good example. if you were the guy who grew that anyone would hire you to grow cannabis. do they have legal hemp growing in OK?

Not trying to be a dickhead but it's borderline impossible to enter the recreational market in Colorado. These guys who are leading it have been illegally growing for decades. These guys are master growers who produce some of the best cannabis in the country. Honestly you're better off distributing in Oklahoma where an ounce goes for $300-350. In Colorado, growers sell pounds for $1000-1200, and just to produce one pound you'll need several plants. It's not much of a cash crop if you're trying to sell in Colorado.

stop with that bullshit about "master growers" and all the fuckrot. its not true. commercially produced shit that isn't intended for someone's personal stash isn't grown well, its grown economically with the least care needed to meet the minimum standards for the market being targeted. my outdoor homegrown is better than almost any bud that you'll ever see for sale commercially. and its not like there aren't a billion localities that haven't legalized growing yet, there will be opportunities in the production field for years and years.

Aeroponics vs Fogponics

File: 1537303824539.jpg -(26245B / 25.63KB, 470x560) Thumbnail displayed, click image for full size. Aeroponics vs Fogponics
Going to be doing my first real grow soon now that it's legal in California, and I don't see much appeal in half-assing it with soil or even hydroponic grows, so I'm trying to go straight to aeroponics.

In the process I learned about fogponics. Is fogponics (which should really be called "vapoponics" by the way) really better than aeroponics? My questions are -

  • The stream of fog is constant. Doesn't that reduce oxygen to the roots vs aeroponics occasional sprays? Seems more like a hydroponic system suspended in the air, which deprives the roots of oxygen by submerging them, vs "the next step in aeroponics".

  • The vapor particles will be much smaller than the fine liquid particles in aeroponics. Can cannabis roots absorb such small particles as effectively? I think of redwood trees which have specific biological systems designed to capture fog (their needles basically), these would not be present in cannabis roots. Would the tiny molecule size hinder capillary action in the roots somehow or would it build up enough in the roots to work just like aeroponic spray?

  • Would the act of vibrating the nutrient solution to create the vapor molecules feasibly distill any nutrients bound to the water? Seems like this would only be an issue if the nutrients were insoluble in water - don't know if that's ever the case as I'm focusing on getting the structure to grow within ready first.

As amazing as fogponics is, it is absolutely the most fickle bitch, but most efficient and rewarding method, out of all growing techniques. To put this into perspective, NASA uses fogponics to grow veggies, and has been testing this growing method for some time now. I think they use it on the ISS as well.

The main issue with choosing this route is that it comes down to two things.

Issue 1: it is not for newer cultivators by any means. The amount of fine-tuning needed is extremely high-maintenance.

Issue 2: most people that use this method report that there's a ceramic part that is used in the process/device to turn the liquid into a fog that tends to break/crack fairly often to the extent that it needs replacing every 3-4 months. (This was quite a few years ago, so the technology may have advanced to where this is not longer an issue.)

To touch on the subject of possible reduced oxygen, just get some good old food-grade 35% hydrogen peroxide. Add 1-5ml/gal depending on how much you want to use. I've been experimenting with 4-5ml/gal and I've only seen good things. The trick to using it correctly is to add the hydrogen peroxide into the pure water before adding nutes and let it sit for 30 minutes so it has a chance to dissolve into said water.

You won't have to worry about the nutrients being less effective as well, since fogponics has been tested against aero and hydro methods, with fogponics being up to 25% more effective than aeroponics when comparing growth rates. The people that did the tests used the same clones from the same mother plant, used control plants on top of that.

That being said, fogponics is something of an end-game method for me. I'm slowly working my way up the latter as far as growing techniques goes. Aeroponics is next on my list of things to try since ebb and flow has been working great for me.

Does anyone know how this compares to deep water culture? I've always held that to be the gold standard for quality in hydroponics but I haven't looked into fogponics.

So after a lot of issues my plant has finally been growing these small buds and it feels like it's getting close to harvest time. How much longer should i wait? the temperatures outside are skipping between 16 and 20°C and i'm afraid it's getting to cold for my little buddy.

16°C too cold for weed? Its not usually a problem. Under 10 degrees is where you can start to have issues with slowed growth but damage to the plants won't occur until you get closer to 0.

That being said from your picture it does actually look like you are close to harvest. How are your trichomes looking?

Do my plants look healthy for 29 days of flowering? (not exactly 29 days, actually - I just switched to 12/12 27 days ago). Also is it OK that dozens of the lower leaves started to wither and fall off since my plants started to bloom? Should I worry about it or it's a natural thing?

There's plenty of floodlights that have been approved for import that come with their own drivers, and prices seem to be well within the range of even the poorest growers. They often fall within the 3000-6000k temperature range, so in theory they're just as capable as COB kits.
I ordered 4 30W floodlights for around $40 in total, but I'm waiting for someone else to admit that they've tried it and hopefully offer some tips. If not, I'll post some updates once everything has been set up and the plants show some results.

Looks nice and will probably look even nicer in 2 weeks, but leave it out as long as you dare. Its packing on more weight and more trichomes every day so calling the 22nd now might leave you with regrets when you're running out of the flower from this plant down the line, especially if there is good weather available after that. Even on a cloudy day the plants are still getting about 100 watts per square meter and they'll grow as long as the temperature is above about 15ºC or so. Just keep your eyes open for the signs of impending botrytis.
The best drying/least loss of flavor I saw last year was a friend of mine who grew somewhat terrible plants, but hung his whole plants to dry in an unheated shed outdoors towards then end of October and waited 3 weeks before putting it in jars. It ended up being a strange combination of ugly, but potent enough flower with great flavor.

Incorporating a lot of woodchips in your soil or as a mulch invites fungus to break it down rather than bacteria due to the lignin. Be careful incorporating it into the soi - this will bind up your available nitrogen in the soil for a year or four depending on soil. But yeah i have a ton in my woodchip pile that's getting regular doses of urine go add nitrogen to help break down the high carbon woodchips. Takes time but it istays warm then converts to mycorrhiza and fungi after anaerobic bacteria end

So i have a mild spidermite infestation. Had some random himalayan seeds that i grew on my windowsill, so they are 3 midget mature plants with a small amount of leafs. They are now in the box. Only tiny tiny webs, but you can clearly see the spots where they eat the leaves. About half of the leafs on each plant are affected, the lower once the most. Already removed one set of the worst.
Now this is a no budget grow, i live in poverty and realistically i cant order anything.
i thought about apllying a spray mixture of soap, garlic and then possibly chili to get rid of them. i know people that say garlic repels them if grown as a companion plant. true ?
sadly no pics of my own until now

OP spidermites aren't fatal to the plants.

Besides spritzing the plants with water to blast them away (which can reduce their population) just try to keep the temperature as low as possible and you will still get a half decent yield.
The mites won't go away anyway.
To completely get rid of mites you have to start over and sterilize the environment.

Next time use properly store bought soil which won't contain mites.

Spidermites adapt to poisons so you need to systematically use different chemicals. There is no one application solution that would completely destroy them.

It looks like a lack of light. Its internodes are few and far apart. The leaves look pathetic like they can't photosynthesize properly. Nutes are there as it's burning but not enough light to use em.

Give it more light. Ventilation for more light. Problem solved.

think the nutrients are burning the leaves??? see the webs and holes on the leaves? I'm at 4250 Lumens currently, I assumed it would be enough. Also it has tons of ventilation and fresh air, though I've been cooling my grow room because I heard it makes it harder for the mites to reproduce.
