How many gallons of solution does the starter kit make?

Our Starter Kit will make between 125 and 150 gallons of nutrient solution.

Do I need to use all of these nutrients?

Honestly, no! You need at minimum Base A&B plus Golden Tree to have a successful and healthy grow. Our additional additives are for use at your discretion, or are needed for certain growing mediums and hydroponic systems. We encourage you to play around with what works for you!

Can I dilute multiple products into the same gallon of water?

YES! All of our nutrients are meant to be used together, and can all be combined into the same gallon of water. Just remember to never combine nutrients together in their concentrated state to avoid nutrient lock out.

Our shipments are sent with discreet packaging.

Are these products organic or synthetic?

Only Golden Tree could be considered organic. 

Do you have a feeding chart for hydroponics, DWC, and autoflower?

Typically less nutrients are used in DWC. If you grow in Hydroponics it is recommended that you use Golden Tree at a lower dose and use Plant Enzymes. We suggest you play around with the amounts of each nutrient and find out what works best for your setup as there are many variations to growing.

N-K-P is short for nitrogen (N), phosphorus (P), and potassium (K) which represent the levels of macro-nutrients. The higher the number, the higher the concentration of nutrients is in the fertilizer.

I can’t reach the correct PPM levels for my mixture. What’s causing the issue?

There could be many different factors. A good start would be to look at your base nutes, potentially recalibrate your pen, and consider the type of water that is being used.

Do these products need to wait until all dangers of frost is over, when using on outside plants in very early spring?

Nutrients will help plants in times of frost if anything be stronger and be able to withstand the frost more.

How old do plants need to be to start your products. I am talking in regards to seedlings I raise from seed?

Most of our nutrients can be used when plants are very small.  The smaller the plant and earlier it is in its life stages, the less nutrients you must use.  Overdoing it when they are small can kill them so if you are worried about that, it is best to feed them when they grow a few inches.
