Nug buckets that plant looks great you will have no problem getting over a lb each cola will easily way over an oz a piece wont it. Watching the mainline like sub said it isnt the best route to go for a hash lover. That being said it does work pretty good for space managment as long as you keep the number of heads down. I have a friend that has a 6x3x7 box that im teaching Your method too so he will be a happy camper when all is said and done. Hes a flower smoker. Myself on the other hand i love my hash and i think i am quite addicted to it now. I start getting worried when its running low its time to make a new batch right now. I dont have the amount of trim to make hash like some people i have run close to a pound of buds into hash but right now im waiting for my ripped bubba, qush, and chernobyl to finish for some extremly good hash. There is one thing that i like also on the main line It does slow the plant down a good bit. But this to me can be good as i only have one flower room. By mainlining it times it up a bit better as far as the space i run. Since i love my hash the mainline will be for a select few strains i have that i wanna flower just to see how good they are. Royal purp Kush, La confidential, ripped bubba, and qush clones will be mainlined and put in a 3x3 box under a 150 watt hps and 3 x 90 watt UFO LED this is not my flower room this is a testing box. I am curious to see how they do under the LED and a little 150 hps all mainlined to 8 tops possibly 4 depending on size. Like Dave from weeden i grow out a few plants for a few other people they like that i dont care for much as there most indica they will get mainlined. You gotta come back in 2-3 weeks to post pictures of that plant when it starts blowin up.
