I ran coco ebb n flow for a year and a half with great results, I fed twice a day with a PH of 5.5-5.8, PPM 800-1200. I would still be running my trays but the new spot doesn't have enough power, HVAC or pluming to set everything up yet and the Mrs. is taking care of everything until I can be there permanent. I also let the coco dry some to let roots search after transplant but don't think its a good idea to do for long. Seems the PH goes haywire when coco drys. I use R.O. and CNS 17 coco and rarely drain and fill the rez unless there's a problem. I just top off and adjust. I learned coco ebb n flow from Dongle69, she was an amazing grower. SirSmokesAllot knows his growing fur sure, he's one of IC's finest. Hope things turn around for ya. I'm also running Ken's GDP, Pre98 Bubba and Platinum OG (not sure if its the same as Platinum Kush) Hoping to get out to grab Kushman's Star Dawg soon. Regardless its always cool to watch a CaliG show. Peace, pot and karma. One Love
