Shagrathanswered grow question 5 years ago Hi there!
I use liquid kelp/seaweed (Ascophyllum Nodosum) as an activator and that is the secret ingredient in AN bud ignitor too.
You simply make foliar spray out of it and feed after the flip and repeat couple times after 10 days.
I notice the transfer to flower has been about 5 days from switch so far with this method.
You can put it in the reservoir/soil too and this way it will boos the root zone too. But Im in the understanding that foliar seaweed is best activator!
