Pot Size For Coco

    OK, this is weird, and I feel embarrassed to be asking such a stupid question. But I'm going to anyway.

    Here's the deal. I've been growing in coco for a few years now, and am really happy with it. I have it down to a system, and consistently average 2 to 2.5 pounds per light growing from clones. Typically, I run 16 clones per light in 7.5 inch square pots, which is just under 2 gallons per pot. This is what I've been doing since the first time I switched to coco, and I've got it down so tight I can do it in my sleep.

    This time, I stepped out of my system a bit. I've accumulated some seeds from friends and other sources over the last couple of years, and decided to grow them out for the heck of it. Instead of splitting the run between half clones and half seeds, I decided to go all in on seeds and use a bunch of different seeds all at once and give the moms a vacation.

    I figured that if I wanted to get 2 tents with 16 plants each, I should probably plant about 70 seeds - I figured 90% germinantion rate, since some of them are 6 or 7 years old, then you'll usually lose a few during the seedling phase for various reasons, and then about 60 to 65% of them wind up female, so 70 seeds would probably give me about 30 to maybe 35 adult females in the end.

    So, I wound up planting 72 just for the hell of it. Got 100% germination, and only lost 1 seedling. I flipped them to 12/12 a few days ago, and most of them are sexed already. It looks as though I'm going to wind up with a lot closer to 50 females than 35 - definitely going to be at least 48, and there are still a couple that may go either way in the next day or so.

    OK - that means about 24 or 25 plants per light, which is way too many for 2 gallon pots. I grow a sort of hybridized sea of green lollipop-style grow, so it's not like I'm packing 2 dozen Christmas trees in there, but it's still too tight a fit for 2 gallon pots. They're still in 4 inch pots, but need to be up-potted within the next day or two to their final flowering pots.

    Adding a third light at this time is not really a practical solution, so what I'm thinking of doing is going up to 6-inch pots, about 1-gallon size instead of the 2-gallon I usually use. I can't help feeling that the plants will get pretty rootbound in 6-inch pots, though. Obviously I'll need to water more often, which is no problem, but I'm afraid that I'll get halfway through flower and the plants will be overly stressed and go hermaphrodite or start popping nanners all over the place.

    Anyone else grow coco in 6-inch or 1-gallon pots? Some of these plants will be 4 feet tall by the time we're finished. Is this practical for coco, especially when growing 4 different strains with different hydration and nutritional requirements?

    Oh, by the way - I'm growing...

    I have a friend who grows in 6-inch pots something of a ScrOg and he puts 50 plants/light. he gives em a week of veg and flips them right away. By the time they are done, they are not more than 2 feet tall. never had rootbound issues.

    Or second solution and i can't say this without tearing up... murder.
    Like my guy at the hydroponic store said: "you need 70 plants, you plant a 100. when it's time to flip them in flowering, you kill 30. It's not very democratic, but it works". :cry:

    Yeah, that's the way I see it, too. I can't bring myself to cut a third of my girls, and I don't have anyone tio give 'em to, so I'm just gonna go for it.

    I said I settled into a system where I plant 16 per light in 2-gallon pots, and do everything the same way every time, and it always turns out great, and everyone lives happily ever after etc. etc. etc. But the only way to learn new things is to try new things, so I'm going to find out what happens when I go with 6-inch pots and water more often. My benchmark is 2 - 2.5 lbs per light, so the proof will be in the pudding. If it weighs out heavier than normal, maybe I have a new method. Less than 2 pounds, and I know my old way was better. One light harvest isn't going to kill me; I'll have 32 more clones ready to roll as soon as these are done, and we'll just pick up where we left off and get righgt back on track.
