Beginning of week 8. Cutting down the feed strength by half before going full flush mode week 9+. Starting to look at tricnome color to determine final day to cut. How long do you flush with rockwool?
I would love to go in more depth of your grow method, I see you have channels, do you use a ebb and flow system or some kind or nft? What spacing do you use for the plants(space between the rockwool)
@100SeedsProject,
The channels are built from PVC rain gutters. The system is ebb and flow, however i run the flood for 20 minutes every 3hrs, so it starts to resemble a NTF while the pump is on. Each cube acts as a mini dam before the water rises and overflows on the sides to the next cube, and so on. There is approximately 8 to 10 inches between each plant. They are lollipoped and cropped to only focus on the branches that point toward the lights. Glad to answer any other questions you got. ππ
@Silverback_Guerilla,
Thank you for the compliment. Wonderwall is a great name for whats happening here. The pictures were taken using my galaxy s7, so that should tell you how pro I am βΊοΈ I'll be posting more about the set up, as I think it is a great use of space. Stay tuned!
You shouldn't need to run clean water for more than a week if you use any kind of chelating agent when flushing.(Clearex, Florakleen, Flawless Finish, Sledgehammer, etc.)
@Canntemporary,
I'd prolly just flush with plain water if you can't get ahold of a pint of Sledgehammer or the like. Along with a wetting agent, those products actually break down the salts very rapidly and the soil or hydro media is quickly depleted of any available nutrients, causing your plants to fade quicker and more evenly...and ultimately, taste better.
@Silverback_Guerilla,
Thanks for the advice. I have yucca powder that I use as a wetting agent. Do you think yucca and water would be a good alternative to clearex?
@Wicked_Stix,
I pump to each channel separately and each channel drains back to the reservoir. There are two sump pumps betweent 4 walls.The 200gal res is in the center of the system and acts as a second floor.
