I started them on G.H. floranova, 200 ppms. Reverse osi sys. water starts at 15ppm. How many times should I be watering with this system? is 6.5 PH ok? Should I move to watering just twice?
smookless Reviewed by smookless on . Rockwool and PH? Hey all, I moved over to an ebb and flow sys, with 6x6 rockwool cubes. I am having trouble keeping the PH at or about 6.0. I am on day 4 with my clones in the cubes. I start the Res. at 5.0, water 3 times a day for 15 min and by the end of the day the PH is 6.5-6.7. the water PH in the cube stays consistant with the Res. Is this normal? do I just keep lowering the PH everyday? is there something I need to do to keep it level? and yes I pre soaked the cubes in 5.5 PH water for 24 Hr. Rating: 5
