I always defoliate about 2-3 days before harvest along with no water and darkness. Just makes it easier to chop and hang.
That's just me though. Anybody else?
The funny thing about growing weed is, ya get stuck in your own ways after so long off what ever, did that really work for me or was stoned & believed !
Some classical stoner literature might suggest defoliation aprox 2 weeks before harvest or about the start of the beginning week of flushing etc
That in some form of 2nd hand history event might suggest the plant may put on its final mass/weight in that period so why the heck are starving it ? never worked it out To Be Honest.
But suggest heavy nutrient feeding may lead to a harsh/bad taste in the final smoked product, hence we might do this ?
