Truthfully you need to rethink what your planning,1st off it takes an assload of highly resinated trim to make any quantity of hash,unless your males are resin dripping monsters your not going to get anything much.
Secondly.why are you thinking about even doing something like this,your 1st few grows its hard to kill off the best looking plants which are most of the time males,it comes with the territory,chop them fukers down & burn or bury them,imagine this,you get pollen sacks ruptered in or around the grow op,your females now make more seed than bud.
So now your really bummed out but you think you've learned your lesson,next grow will be different because you now know that its not worth risking the entire grow over a few males plants that you cant bear to kill,but this grow goes the same way,what started as a great looking grow is now another sausage fest,why is that.
Chances are that you'll contaminate the entire grow op ,the shit gets on your clothes,you can transport it everywhere in hell.
Its like playing with live aids virus then hoping for the best,not a smart move.
You'll hear all kinds of stories from guys saying they kept their males & made silly amounts of hash or oil,its not likely,the only growers that should be fukin with pollen are serious expert growers,not growers with a bunch of feedback dots but real experts,us regular folk need to stick with the easy things,females only.
