False. Water pH'd water only for the last week. You can also give your plants complete darkness for 2 days straight and then harvest. The darkness makes the plant get so much frostier.
does the 48 hour darkness thing really work? have 2 deep purple plants a week from harvest im going to try this on.
Im pretty dang sure it does, I've known a grower for a long time and he actually did the test. Had the same 2 strains vegged and flowered the same amount of time with the same nutes, pH, and everything. The only difference was the plant with 48 hour darkness before harvest really increased the quality of yield. I don't have pics of it but I trust the guy.
