My Reverse Osmosis System Pumps Out water just about 7.8-8.0 pH, now, I have tried growing twice before.
I never adjusted pH in a serious way, I nuted the same amount I do now, and,
It makes a HUGE difference for me.
My plants always seemed to have Something wrong with them when I was watering them with straight R.O. water.
Now that I've started adjusting the pH to 6.4-6.7, the plants seem to look much much healthier, and seem to grow VERY quickly..
But I could be wrong, there could be alot of different reasons my plants are growing quicker, I got better ventalations, temps dropped from 84 to 73, I seem to be doing something right this time around though, lets just hope that continues through flowering.
Working on it Chainer , been helping my family trim 4 lbs, dear god, Im so sick of weed....haha. Snip snip snip, oh , scissors are to sticky to use, have to clean them...I've watched so many buckets of fan leaves be thrown in the trash...
(And by the way , I have grown with CFLs, an they do a pretty damn good job for flowering if you know how to do it, I just dont trust LEDs., For the price, and how new they are , and from the pics I've seen, they do okay vegging, but flowering, looks so small)
