Your Tomato Plants Will Love YOu
This fertilizer has worked great in my dutch bucket hydroponic system. I had previously used a different brand with good results, but that brand was discontinued. I was happy to find a comparably priced alternative that is working great so far. Much better value than any liquid hydroponic fertilizers!

THE BEST fertilizer for your tomatoes and peppers
I found out about this product and purchased a small quantity just to see how it did. WOW! I now use it exclusively with added Calcium Nitrate, Epson Salt and Sea-90 trace minerals with the best results in my life! Dozens of full size bell peppers. Insane amounts of hot peppers and my tomatoes produced such beautiful tomatoes the neighbors were really jealous!

Works
Not sure if it outperformed other products I have used in the past, but my pumpkin did weigh 1040 lbs. I will be using it again this year.

Works well with microgreens
This fertilizer works really well when growing microgreens. I use this (12 grams) and epsom salt (6 grams) for every 5 gallons of water. I know the recipe on the instructions has another ingredient, but I have found it unnecessary.
