Mix all the nutrients in a recycled gallon milk container. Add water and shake well. The whole mix will take an 18 gal reservoir to 2900 PPM.

Add about half of the mix and check your PPM. It will be low so you will have to keep adding nutrients until you get it to 2000 PPM.

It is easy to add more nutrients but hard to take them out. If you go over you have to drain some nutrients /water from the res and add more plain water.

That's why you want to take it slow at first.

Always adjust your PH after you set your nutrients PPM.

Fill the res with water and start adding the nutrient formula until it reaches the correct PPM.

What PPM level you run depends a lot on what strain you are running. 1700-2000 PPM is a safe number to start at but some strains can handle over 3000 PPM.

Every couple of days I add water. As the plants use up the nutrients you will have to add more formula. It's really too easy!

All you need is a cheap PPM meter. You need a PPM meter that goes to at least 2000 PPM. Stick it in the water and read the number.

Same with PH. Just put the meter in the water and it will tell you the PH. If it is below 5.8 you add PH up. If is above 5.8 you add PH down.
