What is really in this stuff?!
Awesome product! Exceptional uptake from my tomato plants. Tried it on my jalapeño plants with marginal to good results. I intend to order again but it seems I have a years supply left.

Absolutely fantastic fertilizer.
I run my chile pepper plants with 400 ppm amalgam of this product plus cal nitrate and mag sulfide. Fantastic lush green growth as well as forming fruits. Awesome! Will buy again when I run low.

Seems to be doing the job
Never have tried to grow Tomatoes without soil before. The plants seem to be doing well and are growing and producing buds. Hoping to see tomatoes set on the vines soon.

Tomatoes are in constant need of nourishment
The Biotech product is water soluble and can be applied in a dedicated pump up sprayer. Tomatoes have a relatively short growing season and are in constant need of replenishing nutrients and trace minerals to support such rapid growth and prolific fruit production. The NPK balance of the Biotech product ensures you do not get more N than P and K. Nitrogen is best applied as a Calcium Nitrate about every three weeks to help with growth as wells as prevention of blossom end rot due to calcium deficiency. The P and K help with fruit production and root development and are essential to producing a good crop.

Awesome fertilizer blend!
This 4-18-38 fertilizer is the same as the “hydroponic masterblend fertilizer” but I use it on my non-hydroponic super hot peppers and it’s a great fertilizer that I use every other day to water them with. Makes those plants grow incredibly healthy so I would definitely buy again when I run out which would be a while lol

Not like master blend at all
As the pic shows… calcium nitrate does not mix well … the real masterblend is on the right or the pic. This product is on the left….. same measurements for both

Very concentrated.
I recently switched to this for its lower nitrogen and better potassium and phosphorous ratios for my hydroponic tomatoes and other vegetables. Within 3 days the Romain brightened considerably and the collards doubled in size while those in the ground fertilized with Miracle Grow only marginally grew. In addition it requires only a fraction of the amount. My tank requires 6 tablespoonful for regular concentration while this requires less than one.
