favorite plants to grow? fish to keep? what problems have come up for you lately?

I had a 50L that was leaking, so I decided on a bigger tank and now both fish and plant are more happy. except for the hygrophila I have growing in the back of the tank. I dose trace elements but no macro's as I hoped the fish and regular water change would take care of that. also no co2 yet, which could also be the problem

So, I bought autoflowering sour d seeds from a reputable onion retailer
or so I thought
I got three girl clones and three girl adult plants going. So far no sign of sacs
But no buds yet, it is day 82, should I be worried? I have them on 12/12

Clones pretty much always are photo-period plants not autos.
They gotta grow a mother plant to cut the clones from you know and that's a little difficult if it starts flowering after 3 weeks.

>TL;DR
>Need help deciding on a way, and ideally a specific piece of equipment, to control atmosphere (temp + humidity) in 96 sq ft, 768 cubic ft, well-insulated space in outdoor temps ranging from approx 25-115 F while minimizing punctures in existing insulation

Greetings comrades. Working on pouring all my money into a setup to try to master fogponics in my first real grow. Probably going to kill some plants. Then make the best weed ever. But that's another discussion.

I have a 8 x 8 x 12 (that's 96 sq ft, 768 cubic ft) grow space. It's very well-insulated; spent god damn $700 on polyurethane expanding spray foam insulation and going to put fiberglass insulation in the remaining space. But I live in somewhat-inland Southern California, so temperatures throughout the year may vary from low-30's (Fahrenheit) to, at the absolute rare-highest, maybe 105 or so.

Thus good atmosphere control is crucial. Because the polyurethane foam is supposed to be such a great insulator, I really want to avoid cutting an air-conditioner-sized hole in it. And because I need both cold air and hot air, I've mostly been looking at heat pumps. Specifically this one,

https://www.homedepot.com/p/ClimateRight-5000-BTU-Portable-Air-Conditioner-with-Heat-and-Dehumidifier-CR5000ACH/207157185?cm_mmc=%7cTHD%7cmid=sQXDDC5wz%7cdc_mtid_890389n25185_pcrid_247823900761_pkw__pmt__product_207157185_slid_&gclid=CjwKCAjw1dzkBRBWEiwAROVDLGsEMCYCxiKKzISS1RH5Wstaboj73F9o9AFSOvk-SEe8YVghlvNOFhoC3jgQAvD_BwE&gclsrc=aw.ds

because it's ducted (small holes through insulation or even just connected to ventilation intake/exhaust) and fairly weak, still too strong for my space but they don't really make them much weaker than 5000 BTU. However if you read the reviews you'll see basically everyone had a shit experience with it. I called Home Depot and they said they would replace the unit or basically otherwise make things right if the company just ignored me, and I tried emailing the company to get some assurance they wouldn't ignore me if I had issues with their product but they ignored me.

SO

>I come to /crops/ for help. Any suggestions on how to handle climate control in my grow space considering these factors?

Also current projected cost of this grow's equipment is like $2,250 even without including the heat pump or any of the structural costs (probably another $2,000) so cheaper the better, plz, I want to grow and I want to grow scientifically but damn my wallet. I don't want to significantly sacrifice on function but I don't have infinite money to blow either.

I'm only growing 6 plants. It's definitely a bigger space than necessary considering that but there won't be a TON of wasted space, just a walkway down the center and 3 plants (going to do SCROG, nebula manifold, and in the second grow probably monster cropping, so allowing for 2x2 per plant). I'm doing this 100% legally as a prelude (and hopeful fogponic proof of concept) to an actual, licensed cultivation business so won't be selling any of it. Also not a fan of HPS over LEDs, I understand their advantages but their drawbacks combined with the fact I like to think I'm an environmentalist combined with 110+ degree CA temps making heat a major consideration sold me on LEDs.

I'm also not a big believer in upgrading vs just buying the best (or at least reasonably decent) equipment to start with.

Maybe I totally misunderstand how mini splits work but I thought it was basically like installing a wall mounted air conditioner where you cut a hole basically the size of the unit? Any chance you could post an example of one with the coolant line connection you're talking about?

As for the home depot unit, I could just attach a carbon filter at the end if necessary. And yes it's on my family's owned property and 100% legal.

On mobile and I hate typing on mobile so sorry if I seem abrupt. Greatly appreciate your assistance comrade, seriously

I just searched for
split air conditioner installation
You need to hire a refrigeration technician to install it, which often costs as much as the device itself. They need to fill the coolant line with refrigerant and so on.
The advantage is you can have multiple indoor units for one outdoor unit, higher efficiency and quiet operation.
Since your family owns the property you might want to talk to them about installing a system for the whole house too.

In climates that do not go below freezing it's also the most cost effective heating solution afik.

Ahh see I was thinking mini-split rather than split AC. Mini-splits can be under $1,000, usually around $600 for the weakest (which is all I need)

In that case, yeah, that sounds great and is probably what I'll do for the actual business, but for my backyard weed shack, $1,000 low-average unit cost and $2,500 low-average installation cost is a bit above my price range, yeah

The LEDs themselves are also only about half the cost.
The heatsink and driver costs amount to about the same when ordering decent quality.

But if you are really that cheap:
230V mains
https://www.aliexpress.com/item/COB-LED-Lamp-Chip-220V-Smart-IC-No-Need-Driver-Ampoule-LED-Bulb-Flood-Light-Spotlight/32951276228.html

You can probably find a 110V version of them if you really need them.
If you go ahead and get a bunch of old cpu coolers from somewhere you could pretty much rig up a ghetto light system for dirt cheap.
You'd be handling mains electricity though, so good fucking luck!

For the ones of you that do run / think about running a reverse osmosis system for hydro:

This is what I am planning:
All of the osmosis related stuff is below the kitchen sink.
I want to use the tank both for storing the osmosis water as well as mixing the nutrients in.

I will equip the tank (a large drinking water canister) with a ball valve.
My osmosis system will automatically shut off once the ball valve shuts. (It's supposed to do that)
Then I will remove the filling cap of the canister, add nutrients, adjust PH, etc.
When finished I have a hose that I put inside the hydro res.
For draining I want to utilize the pump that is already in the hydro system.

I plan to do this process once a week.
Any thoughts and/or pointers?

changing the water that often is a waste of nutrients in my opinion, especially during early vegetation. It's only necessary if you're trying to stave off root rot with constant water changes rather than refrigeration or by adding beneficial bacteria, both of which are better options imo. Once you switch the lights to the flowering cycle the plant will be using a lot more nutrients and there's the possibility for salts to build and for nutrient lockout to occur so it's best to change the water more often but early on when the plant is small it's probably not needed. Keep in mind that plants can drink as much as a gallon of water per day depending on their size and atmospheric conditions so you're going to need to top off even if you change once a week. I like to keep some strong nutrient solution and some plain water and add in the amounts of each that I need to replenish my reservoir while also keeping my nutrient levels stable.

you mean drain2waste? Because the other one is recirculating, that's what I've got.
It's a ebb'n'flow system.

Drain2waste is only feastible for larger systems.
This will be a 250W 60cm grow.
If I had 4 times the area and 1KW of lights I'd think about it.

But as it stand there is no space.

Ideally yes, topping the reservoir off would save water and nutrients.
I'd have to just try what works.

And again it's a 250W system with a single plant, if that one gallon figure is accurate I'd have to change the fill the reservoir twice a week at the very least.

The nice thing is though I can always dim the lights and as I am using a 60cm tent the plant should be fine with half that power (It will be 170lm/watt leds)

Either way you slice it once I probably have to change the solution once the water level falls below 30%. Topping it off at that point might be possible or not, but I doubt I can do that more than once before having to discard the waste.

So, my plants are looking a bit afflicted and I can't seem to find anything that matches the looks of the symptoms exactly.

*It's an outdoor grow
*The plants have been growing healthy and fine up until flowering
*Now the leaves around the bud are curling in odd shapes and directions.

Could be an insect infestation and I'm going to be spreading diatomaceous earth to slow it down while diagnosing.

Anyone see this before?

Hello there fellow green fingered nerds.
Gonna do a loose grow log and hopefully entertain you bunch of degenerates.

This year i'm growing 7 plants. All femenized seeds from a selection of banks.

G13 Haze from barneys farm x3
Jack herrer from greenhouse seeds x1
The church from Greenhouse x1
Cinderella 99, seedbank unknown x2

They popped out of the soil end of april. Using 8ltr water containers for watering, watering each one around 3.4 litres of water daily. Feeding pretty much daily.

Using Hesi neuts and have used the hesi soil neut chart as a rough guide.

They're growing on a roof terrace and I use LST and super topping methods as we have neighbors.

As summer solstice was yesterday thought I woulds start documenting as the more fun changes start to happen soon.

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?

Leaves that don't receive any light don't provide photosynthesis though, they're just dead weight. Plus snipping them off gives your plants a little spook, so they'll grow bigger buds because they're afraid of dying.

Kinda fucked up, now that I think about it.

Anyway holy shit OP I thought my first photoperiod grow was going pretty well but god damn I have a tiny shitty dwarf plant compared to your ubermensch stalks. Dang.

True, they're not completely useless. I've gotten high from vaping just van leaves before, not even any sugar leaves. It's a myth that they contain no THC, but they don't contain that much. Probably best to use for cooking. You can blend up the entire plant, then throw it in a crock pot with a few quarts of some water and coconut oil for a few hours then put it in the fridge and scoop up all the solidified coconut oil and throw the rest away.

The plants xylem moves water and nutrients from the roots up into the rest of the plant. The leaves need these nutrients in order to photosynthesize. The phloem moves glucose and amino acids that are produced from the leaves during photosynthesis to other areas of the plant that need them because they are growing like branches, new leaves or flowers. These are both physical passageways and there's a limited amount of space in those passageways. People do stuff like LST and HST (supercropping) in order to widen the stems and widen these passageways so the plant can take up more nutrients and water.

Your lower leaves on a mature plant are the ones that formed earliest, their phloem, the passageways that take the sugars produced by the leaf where they're needed, are connected to the lower branches. Each successive level of leaves during vegetation is connected to the branches that are farther up. Once it comes time for the plant to begin flowering, it puts out leaves that connect their phloem to the flower sites rather than the branches.

Some rerouting of nutrients can be done and the lower branches can contribute some sugars to the lower bud sites, but they will do so extremely inefficiently because the physical passageways simply aren't connected strongly. In order to keep them alive the plant needs to continue to move water and nutrients through the xylem to those lower leaves, but since there's a limited amount that it can move through these passageways, that means the upper bud sites get less water and nutrients. Once the plant is done with its vegetative growth and has reached its final height after the stretch, the lower branches no longer need any nutrients because they're not growing anymore so you should remove them so the leaves don't take any water or nutrients from where they're needed up top. Their large size makes them take a heck of a lot of water to maintain so they become a net drag on the plant (which is why the plant often naturally abandons them).

Can somebody please help me figure out what's wrong with this plant, at some point I did cause some nutrient burn but that's fixed now, but I can not figure out what is causing these white spots. It honestly looks like some kind of pest rather than a nutrient issue to me, but I cannot see any insects on the plant. This is my first time growing so I'm a bit lost at the moment.

there are 3 possibilities

  1. When you water droplets of water get on the leaf and the water magnifies your ligh burning spots in the leaf.

2. Some sort of mite it doesnt look like spider mite infestation but i would check under the leaves with a magnifying lens to see if you see the webs or tiny spider looking things.

3. Thrips which in my opinion is the most likely, The way the eat the plant is they rub thier face on the leaf until they get to the sap. Thrips arent ussually a huge issue for cannabis production.

Make sure you dont have spider mites ,
if you do have spider mites spray water on the folliage of your plants daily and maybe put on neem oil if its not flowering yet.

All I really do is spray the plants down with insecticidal soap or Neem Oil and cut off the effected leaves. If the plant is still in veg, it should be fine after a bit of recovery time. Wash the leaves the next day and try to get rid as much of that honeydew as you possibly can. Do this once a week or more and you should see improvement fairly quickly.
I also crush the effected areas between my fingers, which can damage the leaves but since the little fucks already destroying the leaf, it's not that much of a problem. Just killing the miners by crushing them can slow the spread of an infection.
Just make sure you remove the worst effected leaves. It's better to wait a few more weeks than lose an entire plant to a pest that won't go away.
Spinosad apparently works against them, but I've never seen it sold at any retail shops.

yup, looks like spider mites. Leaf miners leave damage that looks different but this is pretty typical of spider mites. They look like tiny black dots and leave behind little white spots like that at first. Take the plant outside and remove anything heavily affected, then spray it down real good with a powerful enough jet of water that it will knock them off, then spray on some sort of repellent or killer designed for them. They like to hang out on the undersides of leaves so make sure to spray that real good. The eggs are harder to kill so make sure to keep using the insecticide regularly even after it seems like they're all gone so you kill anything that hatches.
