Nearly doubled plant growth in 2 days opposed to regular ferts!
Size: 8 Ounce
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 Hu
mboldt 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.

When buying this product on Amazon it does not say anything about needing Humboldts Secret Golden Tree.. mind you Golden tree is 50 dollars for a half the size as A & B.. the nutrients table tells you u need Golden Tree

I have used Humboldts Secret for 3 years now, and it works amazingly well, I wouldn't use anything else to grow my plants.

It's to early to really tell, however the plants do seem to be enjoying this lovely mix.

I’ve been growing houseplants for 50 yrs & have never used a product that works as well, as quickly as Humboldts. The Peace Lily pictured had 10 blooms-at the same time. My brother & niece have since bought it & I gifted it to my BFF. I’m telling everybody about Humboldts!

Wants you to buy additional products.
Size: 32 Ounce
This stuff probably works great. Nothing noticeable after only a week. I have high hopes. I won't be buying anything more from this company because they suggest buying an additional product for it to work well. This was never mentioned in the information on the product description. I feel a little sc
ammed, I would have bought it if it would have been mentioned. I bought this just for my regular garden veggies, I will write a glowing review if my garden does better than normal.
