i got two of those lights up in my room, so in general i have 200 watts of light on my babies...i know i got one or two females but i aint risking any of them byu killing one or two of them, i know people dont like males but i do know they are still smokable might be less of a high but itll still fit in a paper....to tell you something i only started to grow to see if i could save some money since gas is so damned high...hopefully i can get that high...to answer they can get as tall as 10-12 foot i dont know exactly how big the last pot was but i do know it was no where near to the tote that im using now is...i think i might try molasses..ive been feeding mircale-grow plant food but ive been looking for a 10-30-20 mixture havent had any luck, but today im going to call the farmers co-op and a few other places..i think that the floro doesnt work as good as it should but ill try it
