B1/ Thiamine is an important component of SuperThrive and commercial transplanting solutions.
It's good in veg, but personally I would only use it in flower ONCE, and then, only after a transplant, and that's not even necessary.
It's a stress reducer and will also aid in re-vegging a plant that has been harvested, if you ever get the wild hair to do that.
stinkyattic Reviewed by stinkyattic on . Vitamin B1 Got some free Supermax Vitamin B1 Seaweed based nutrients 1-2-1 by Optimum Hydroponix. Currently using Botanicare pro grow and bloom in a soil substrate and am wondering if this B1 is a good addition to the feeding schedule? If anything I would like to foliar feed with it 3ml/Litre. Any comments or does anyone use something similar in their feeding regime? Rating: 5
