I checked out the sure to grow media blocks at my local hydro store. They are really light and fluffy. I think they are basically spun polyvinylchloride fibers. They are too expensive for my taste. I sent an inquiry to Aqua Resins Technology to find out if there is a current supplier in the US for Fytocell. Wl post what I find out. Honestly, i will likely go for the chunk perlite if I have to. It holds moisture well and is airy enough, and especially cheap enough.I did not like coco. My own opinion though. Plus, i am finishing a build on an AlBFuct perpetual grow, but in independent NFT tubes so I can move their arrangement based on their status in flower(quick connected). When i finish and get it running, a journal will follow.
Just sucks on the Fytocell because i am saving the last bit I have to use on the Sweet Tooth x3 when it gets here.
