Well I'm a super noobie at the DWC so right now I'm using ten inch airstones from the pet store (also available at Walmart pet section)
but I may change depending on how these do. I've used airstones in my fishtanks for YEARS so have some experience with the fish ones but have never tried any of the airstones or diffusers made for hydro applications.....AS YET anyway. I plan to be using a partial DWC setup for flowering for all my plants in the future as well so if I find something I like better I'll let you know.
Weedhound Reviewed by Weedhound on . Third Grow I am at Day 19 of flower in my third grow with 9 Master Kush. My bins drain completely this time around and my roots are super huge which I think I owe to the drainage. I am having some yellowing for some reason, but I just changed the res and upped the PPM to 1100 last night so hopefully they will turn around. The plants really took off in veg which I was not expecting, so I had to tie a few of the plants down to keep them away from the 1KW HPS bulb. The first pic is my whole grow area, Rating: 5
