There is a GH chart in the FAQ too.
Zandor Reviewed by Zandor on . Recipes for GH Flora series for cannabis http://www.overgrow.com/growfaq/t47 not sure how to link it but that's the web address anyway. Seems like a lot of people are asking about how to use GH 3-part for cannabis. Most people use or talk about the "Lucas formula" probably because the name is easy to remember. I use Floranova series which is very different. It's chemical AND organic. I use all GH supplements plus a few extras good for yield. Rating: 5
