My point exactly. Growing fro mseed then takign a cloen fro mthat seed doesnt benefit you all that much. You actually lose alot of your size by far.. you only gain what clones normally have to offer over seedlings..I think the reason they wanted to use seeds only is so that everyone was starting from the same point.If they allowed clones, then some ppl may be having a slight head start due to their clone being further ahead rootwiseor something. The thing is they said you can only do one cup- no starting 10 looking for a female- so I think alot of those guys burned a fem seed....
as far as growing inside the cub.. what if roots exceed cup space and grow (overflow) the top of the cup?
