Great product plants responding excellent

Mark M.

I never used ANY special nutrients on my plants. Alaska Fish Emulsion, Cal-Mag and Espoma 3-4-5 Flower-Tone supplementing a high quality soil had worked well enough for a long time, but I wanted to try something different. I did a lot of research and and quickly rejected several brands out of hand. Then I ran into an article about Golden Tree....then another....then a Forum post....a blog, etc. It seemed that a bunch of people swore by the GT even if they didn't use the entire Humboldt's Secret line of nutes. I decided to try the Golden Tree and Flower Stacker just to size them up. One season was all it took to see my yields double. Plus, I wasn't seeing as many signs of deficiencies as I had before. I started using GT it on my houseplants and all of them loved it. I purchased the entire small kit and began using it exclusively. The results are nothing short of remarkable. If you are looking for a good all around nutrient / supplement line you should try HSS. If nothing else get the Golden Tree and see for yourself.

Finally! A product that does exactly what is claimed. Seedlings to two foot tall plants in just a couple of weeks. We are impressed.
