rhizome Reviewed by rhizome 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
