    • Nearly doubled plant growth in 2 days opposed to regular ferts!
Size: 8 Ounce
Review Image by parker parker
This stuff is legit. Has made the plants so healthy and full. It corrected any imperfections and dark spots on the leaves within days opposed to more traditional fertilizers. If looking to used for your “favorite plants” I highly recommend it. Will be using in combination with a few other products Humboldt offers. Very concentrated although I would recommend the next size up from my bottles as I could see it going quick with multi plant use once they produce fruiting bodies and flowers. ... show more
