Best fertilizer for hydroponics.
I live in Florida and have four hydroponic systems outside. The heat and sun is rough on the plants and gardening is hardest in the summer. Thanks to Jacks I am able to continue to grow in the summer. Easy to use and gives the plants everything they need to thrive.

You can trust this product is next level from bottled nutes.
Skip them all and come straight to Jacks. I promise you will have the dankest harvest ever. It makes a huge difference and I have tried several others over the years. Jacks is my go to for this. I learned about Jacks from a world class grower with multiple cannabis cup wins behind him. You will never look back.

Seems to be working well so far.
It takes a little bit to dissolve, but seems to be helping the growth.

Great alternative to other tonics
Great alternative to the expensive tower Garden Tonics, for much cheaper. Just make sure to keep in dry place.
