Whats up h8red? Iam new to the whole hydro but have grown in soil numerous times this last grow i went with an ebb n flow system. my set up is a 2'x4' tray with a 18 gallon res. Grow medium is coco croutons,coco pyth, perilite mix, i flood the tray 3 times a day for 15 minutes when light is on . i Clean the res out every 7-10 days, its important with ebb n flow to use clearex after emptying res. I add 1/2 ounce of clearex per gallon and run in tray for up to 1 hr or until ppm's stop going up then i rinse grow medium with clearex until totally saturated, empty res . After that i uses H2o2 1/2 tsp per gallon for 20 minutes and then add nutes. It took me some time to figure this out but depending on ur grow medium flood tray to about 1/2 of where u think the roots are so u dont over saturate the medium. Hope that helps, like i said im no expert on ebb n flowsgot two 15 gallon rubbermaid tubs on stacked on top of other????do i have to use rock wool or can i just use groaton rock and if so how and what do i do ALSO how many times should i flood the sytem and for how long need some help from my
