Setting up a grow room or two. by Charles Fevingpit - Wed, 12 Apr 2017 21:49:55 EST ID:ZTG8+Ksl No.144539 Ignore Report Reply Quick Reply

Say I have no experience growing except 2 failed grows, zero, nada and I've only watched a few documentaries, read a book on it.

Could I pull off a 40 to 80 plant grow room and actually harvest from it?

Any ideas or tips?

I'm going to be using 5 viparspectra 600W LEDs for it, and I'm thinking of planting 40 Gorilla Glues from Fast Buds.

This is going to happen whether I like it or not and I have to be the one to manage it, also no one can know about it so I can't just call in a botanist to come take care of it.

Money isn't an issue as I have about 10 to 20 thousand $ to set-up this operation, I'm going to use soil and I'll be using Advanced Nutrients products(The master grower segment from their site).

I'm going to start the grow with 15L pots from seedling to harvest, it's going to be LED lights 24H from seedling to harvest. I'll have the exhaust fan on the top of the building and intake at sides both at low setting as I'll have the AC on full-time to make sure everything is the right temperature, around 21 degrees celcius(70F). I'm going to have the PH always at 6.5

Only if you understand the basics of growing, and some math. I would recommend searching grower forums for 40-80 plant grows and follow what those growers do to a T.

So I will be buying seeds in the distant future from Attitude (https://www.cannabis-seeds-bank.co.uk/) and as you can see, they have a lot of seed banks to choose from. I was wondering what banks/brands were shady or low quality and what brands were the best? In other words, why are some feminized OG Kush seeds $5.00 from this brand, and others are $20 a seed from this other brand? Isn't OG Kush always OG Kush? I don't want to overpay, but I also don't want shitty seeds.

To some degree, yes.

The nature of weed makes it a bit of a shot in the dark, for one. Weed produces a lot of phenotypes. So, even a plant that has been bred true for decades can have short individuals and tall individuals, etc...a wide variation...within that genepool. Every seed is different.

On top of that, throw in the nature of the market (not exactly regulated,) and the fact that nobody is keeping studbooks or whatever you do for plant genetics. Yeah, it can be a crap shoot. Especially with "newer" strains. They may not be as stable as say a Jack Herrer or Northern Lights.

Micronutrients have their way of being deficient in an inside grow also. Outdoor, not so much. And if their PH is way off or PPMs too high, so many nutrients will be locked out that it won't matter how much you feed it.

Bluelab also finally came out with a soil PH tester a few years ago, so you can test after you water instead of assuming the soil's PH before you water and only adjusting the nutrient mix. Best 130$ you'll spend, or try and find a kit that includes their truncheon meter for PPM adjustment of the nutrient mix also.

I'm addicted to planting tomatoes. I get a rush whenever I see a new tomato seedling sprout, the way it sort of unfurls its stem and then spreads its cotyledons. I've planted 474 so far and 79 have sprouted so far. I didn't plant them all at once.

I plant like 1 or 2 trays of 72 now every few days. They're all heirlooms. I love them but I'm getting obsessive about watering them and making sure everything is moist.

Has anyone else had this problem before? How did you get out of it? I'll be caring for too many plants soon and I feel like I'll be consumed by it all.

What started with a few cannabis seeds turned into a full-blown gardening addiction. The local supermarket isn't helping either, they're giving away little herbal seed packets with each 15 bucks spent on groceries. I've already germinated a couple of sunflower seeds and have three more packets waiting to be planted tomorrow. (I need to get some additional dirt first.)

My entire living room will soon be full of potted plants. Help.

Well, pot was just made legal in my state, and I'm allowed to do 6 plants per person. I'm teaming up with a friend, and because of space constraints we are gonna grow outdoors. Hoping you folks could help me answers the following questions.

  1. What is a good place to buy seeds from online?

2. What sativa heavy strains do you recommend growing in a colder place like Maine?

3. Should I buy feminized or not?

4. What equipment do I need to get the seeds to sprout?

5. How long will I need to take care of the seeds indoors before I can safely grow them outdoors?

Anywho, another recommendation is that you hit up FB and see if there is a local grow group. They are popping up like weeds since legalization. I'm in one for Mass home growers, and there can be some really good advice there. As well as connects to growers with locally-acclimatized genetics. I know there are many old growers up in Maine who have done non-auto outdoor grows. For decades. Probably some Northern Lights/Thunderfuck genetics that have been selected for Maine weather over the years.
So, yeah, sign up for some groups on FB since this is now legit. I'd look heavily into autos for your first outdoor grow. I have a decent amount of indoor experience, and could do a standard outdoor grow, but nope...autos. Autos all the way. What it does is, it buys you some fuck-up time. With autos, you can squeeze two crops out of a season. A spring-summer/summer-fall system works well for them. Plus, they are more discrete than some monster plant that screams "steal me." Anywho, if you fuck up with autos at first, you can still salvage the growing season.

And yeah, autos aren't quite as potent as normal weed, but the have gotten very good recently. Nothing to ignore.

Came across a riddle...

I have a little thermometer that measures the high and the low temp in my grow tent which is in veg right now. I am noticing that over a 24 hour period, I am getting a high of 99F! Always the same temp. But, whenever I check my current temps at any point, I get around 83F at most. Very stable it seems. Even my low temp is steady at 64F. But, why this spike?

The only thing I can think of, is that the bulb throws off more heat than light while warming up. In other words, while it may be dim to look at as it starts to cycle up, in reality, it is pumping out a shit load of heat instead of light.

Just a guess. Any other theories on my mystery 99F?

It isn't spiking with the door zipped up. I check the temp immediately after opening. It doesn't have time to cool down. And I have a fan already going full blast cooling the hood.

I also just got a nice harvest from this same setup with an HPS bulb.

I will say this, I get 5 degrees of cooling depending on where the little clip-on fan I use for general airflow is aimed. Really makes a difference!

Plus, my growth is going great. Hmmmm.....

Well the only way to know for sure is to, if you have the skill, set up a temperature probe that will close a circuit at 85F or so, have it on the ground side of the circuit after the load, then put a small beeper or alarm (as the load) into that circuit, stick it in there with a small battery, and when it goes to spike you'll hear the alarm beeping. If you run and open it right away, the cause of the temp spike should be obvious at that point.

Yeah. I need to peg this down.

One thought I had, is that my issue isn't when the bulb STARTS, but maybe when it STOPS? I have the exhaust fan for the hood on the same timer as the light. Maybe I am just radiating out a lot of residual heat when I turn the light and the fan off. Temp spikes because the fan is off and the heat is still there.

If that is the case, I have a problem. That extra heat is very useful in getting me through the "night," with these plants. Temps without that extra heat might get too low at night.

Shit, what I need is a thermometer that will do minute increments or some shit and then let me see what is happening on a graph. That would be a very useful tool for me.

Wait, you're cutting power to the bulb and the fan at the same time? If so, yeah, that's the reason that HPS and MH bulb manufacturers say to pull the plug out of the wall for 15 minutes after a power outage so the bulb doesn't restart hot. You have a ton of built up heat that will soak the whole tent if you turn the fan off at the same time.

Get fem seeds if you plant them in the ground.
Removing males in a outdoor grow leaves ugly gaps between your plants. Yes the remaining plants can grow to fill the gaps but you can't plan for it.
In a (successful) outdoor grow space is the most important factor and that is just one way to make sure to get to that.

The other factor is digging _large_ holes in the ground filled with proper fertilized soil. (You have to be able to stand in it with both feet and the ground till the knees)
You don't want to spend several hours digging holes only to have to kill the plant.

That's if he has the cloning supplies and knowhow. Since he's asking if he should get feminized or not, I guess I was being forward assuming he doesn't grow regularly, and if he is new to it, it's better that he has a chance at 7 or 8 females than 5.

So I might want to buy a grow cabinet and seeds for a personal grow. The problem is that every time I see someone ask a question like this, everyone says "DON'T HAVE GROW SUPPLIES AND SEEDS SHIPPED TO YOUR GROW LOCATION!!!!!!!" Which sounds good and all, but where the fuck do you get that stuff sent to if not your house? I don't have friends/anyone who would accept a package for me (kind of a loner/introvert) and I'm not a multimillionaire who owns multiple properties.

First off, where are you? The law on this is different by country.

Secondly, you won't go to jail in the US for ordering this stuff. It isn't even probable cause. Want to CYA? Buy about 5 packets of seeds from some company right at the same time you placed the order. Anyone looking would see you like tomatoes and lettuce or some shit.

But yeah, nobody is building lists of this shit. There have been a handful of cases, but they all included more evidence than the supplies, and not a few have been batted down by the courts.
