## Questions & Answers

**Q: Does anyone know how much to put in per gallon for a Hydroponic setup?**
A: This is for 5 gallons. I have been using this for tomatoes works great. 12 grams of the fertilizer. 12 grams calcium nitrate. 6 grams Epsom salt . You need gram scales. 28 grams in an ounce so not hardly half an ounce

**Q: I'm growing tomatoes and peppers in 20 gal. containers, what else do I need to go with this fertilizer?**
A: Calcium nitrate and Epsom salt is all that's needed along with this. If in soil no need for pH down but if you using soiless mediums then just pH down your solution about 1/4 teaspoon to 2mls hope this helps. :)

**Q: As side dressing when tomato plant is already producing large tomatoes, how to use? sprinkle on soil or mix in water and pour on soil around root??**
A: Hello,

You can use either way. 
If you would like to use for a liquid application you will need to dissolve 2.5 grams of fertilizer per gallon of water, and then poor onto soil.
Depending on the quality of the soil amounts vary, but one gallon of solution should be enough for about 15 to 20 adult tomato plants.

**Q: Can you put this straight into the reservoir of wicking tubs?**
A: Hello,

You can add it straight to the tubs but we usually recommend dissolving in a bit of water first for easier mixing.
