beanzy, i got over 8oz but that was also cuz in the middle of flower i went to jail on a 5 yr old proby violation charge n my old lady had to take over with me giving info in jail lol. needless to say i think i coulda got 10 oz. i dont think i will get up to a lb without a 600w or above. i plan on switching to a 1000 when i move the space elsewhere. Timbo, im not one of those douchbags that flame people even when they say stupid shyt. just aint worth it for me. as for ur question dont top or crimp during flower, this is a critical phase of the plants life. do all ur supper cropping in veg time. my girls go 4-5 weeks no more in veg, im not saying thats the only way but it has worked great for me since the 90's. it is 16 inches between the screen and the top of my res, it normally takes three weeks for me to get to 16 in with no super cropping. so in order to keep on schedule i start crimping at week two give them time to heal if im going to top i usually do it in week 3 and take them to five weeks, by then they are about 17 in high put them into the screen to flower and let them run. now this is my way others jay do it differently
