I've been using aptus fascilitor for a while now. Good stuff but pricey. Can get it on sale sometimes for $60-70 sometimes for the 250 on sale. 0.5ml/galHey hey hey! Good evening monkeys!
Check the concentration of it and compare to others. There's a big difference in a lot of those products. I've used Silicium and Power Si. Really like the Silicium!!! Grow Genius is another and Mills that you're using has one etc...
I used Tribes which was one of the first microbe products from Impel. The Green Genes guy has some vids with some info on it.
