I use Jacks Professional Hydroponics (A), and Calcium Nitrate (B). Roughly 1 Tablespoon of each per 5 gallons water through the whole grow. I dilute it to 25% after rooted, then increase too 100% from Veg to Harvest. It was made for Cannabis Hydroponics growing, but also worked Great in soil.Very cool! I would imagine it's endlessly reuseable? Do you use it with synthetics, or with organics, and do you need to flush it from time to time?
It is clear with a blue tint, ph stable with a slow drift which makes Everything it needs available at all times. I add only, no res changes, no flushing because it doesn't get hot spots. No air pumps, No chillers, No deficiencies, NO problems EXCEPT Explosive growth!
Imagine being able to Set it and Forget it, and focus on environmentals and Training. Easy Peasy!
