I have a few. I'd say SM-90
for cleaning and sterilizing my aerocloners and pucks, as well as it being a great wetting agent. The smell is also delicious.
I also love RAW's products, especially their kelp extract
and their fulvic acid
. These combined make an ideal spray at a 5:2 ratio to keep mother plants amped up for taking clones from.
Also from RAW, this yucca extract
is outstanding for general root health and as a surfactant in foliar sprays.
Lastly, I'd say Z7
. I've never seen anyone discuss it, but it's an enzymatic cleanser that keeps roots protected from pythium and other nastiness. At 1/2 ml per gallon it lasts a long
time for the money.
