Having read what green gain is about, I've search online for a few other items. One of the item I came across is this Cytokinin: 6-Benzylaminopurine 25 Grams (PGR) http://cgi.ebay.co.uk/Cytokinin-6-Benzy ... 27aba98591 Theoretically by adding this to the tank after pruning, your plant should be able to recover faster and produce more side shoots i.e. similar effect of green gain. Is there any chemist out there that can clarify if this will be safe for fish? And If I'm adding to the 10 gallon tank, how much do I need to achieve 1000ppm? It will be easy if I can just dilute this into water and just dose a couple of drops every water change. any thoughts?
