I used Superthrive (which is a b1 hormone) to take the clones from a cup of water and put them into my starter pots. It worked wonders! Do you guys use the b1 when you transplant into a three galloon or whatever your finishing pot size is?
razzapiggy Reviewed by razzapiggy on . When and how to use Vitamin B1? I'm going to be needing to transplant within the next couple of weeks - how should I go about using the B1? I just got the bulk one gallon B1 from Home Depot - should I dilute it more than the label suggests? Should I use it more than once for the same transplant? Thanks! Rating: 5
