Well, Hudson, I have a dilemma there. Obviously, I did not think things our thoroughly. I have 20 plants going now. I expect that vast majority to be female. I used a chart I found on the boards here that shows you how to determine the sex of seeds. It may be BS, but I have hope. I also expected some of the seedlings to not make it. Long story short, I do not have room for 20 in larger pots. 10 of them are a few days older than the first 10. I expected attrition to lower my count, then I could select the healthiest of the remaining for transplant into larger pots.

The more time I have invested in this, the less confidence I have they are all female.

They are currently in 2"x2" peat pots. I have looked at the bottom and a couple of them has a root protruding through the bottom. I simply tucked them back into the pot. With these pots being degradable, I expected to see some root trying to break through and that would be my indicator to transplant. I agree with you, I am not going to be able to wait that long.

Original goal was to have 5 or 6 thriving females out of the 20 seedlings. I am now getting greedy and want to find a way to keep them all though I know this will not be possible.

I have read on here in several places by several respected posters. that they all try to limit transplants to 3 or 4 max. I believe the max pot size I am going to be able to use is 3 gal. At a gallon per foot of height, that would limit my height to 3'. Which I would not have a problem with if I could keep 10 plants going. I also plan on LST and am giving serious consideration to SCROG. This would further limit the height I could get in 3 gal pots.

I really am not interested in pre-flowering to determine sex and then going back into veg. Do not want to pay the 2 weeks price...

So I am probably going to go into flower at 12" tall with the plan of SCROG to a max height of 24" in 3 gal pots.

Forgive my rambling, but do you think I could get away with transplanting to 4"x4" pots for now? I believe I can fit 20 of this size. Then, at some point reducing to 10 plants and doubling the pot size. Or should I go ahead and thin the heard to 10 now and get them in larger pots with the reality of ending up with only the 5 most vigorous plants?
