It doesn't get better than DTW - HPA system with a massive root chamber.
It really comes down to a few questions:
1. Do I want to be as efficient as possible? (hpa saves 90% of water use) (hpa also requires nutrients to be run at half strength)
2. Do I want to be as effective as possible? (hpa provides the maximum amount of osmosis and nutrient uptake)(hpa grows faster and produces larger fruit)
So I donno, I like saving 95% of my nutrient/water costs and 100% of my medium costs. This is alot of money if we are on a commercial scale, even alot in a 4 light garage.
I also like not having to dump a 100gal dirty reservoir every week. Or throwing away rockwool cubes or hydroton, and even worse remixing coco or soil every cycle.
Everyone else does too much work for me..
i'll sit back saving money and doing 95% less work..
got hpa?
