im gonna start a thread about this.. I want as many opinions as i can get, but i wanted yours first..You won't have to change your nutrients at all. Just follow the ratios recommended by the maker. however, keep them lower than they recommend. The best results I've seen from DWC has been with lower PPM. Ignore the people posting their 2000ppm pics, it stresses the plant. Many growers that have been using this system for years prefer PPM under 600. I run mine under 1000 (prefer the 700-900 range) and I run a couple more additives than them.
Also, I never drain my system anymore until the last week of flowering. In fact myself and many other growers that use compost tea in their deep water system save a lot of money in the long run because we never empty our our systems until we are doing the last week of flush. I just stay at 800-1000 ppm and top off until that the last week of flush. More importantly we get RESULTS. Great taste, yield, healthier plants..etc. You'll love compost tea too.
Seeding your compost tea:
I forgot to mention, you can actually save a lot of money by just SEEDING a compost tea bucket. Because you're just using the humus and castings to "seed" your compost tea and breed the beneficial bacteria that comes from them, if you have a dedicated compost tea bucket you just need to keep it aerated and add food (molases) every couple of days. So you really don't need to buy big bag of worm castings/ humus. You just need to seed your compost bucket once and keep that air pump running 24/7, top off with water, and feed your bacteria as if it was a fish tank. =) It's also cheap.
There is a local hydro store owner that sells her compost tea for over $12 a gallon. She just seeded her large 200 gallon brewer once, and now just adds some molasses and sea kelp twice a week and tops off with water.
@Wisher619 so i copied this from another thread thats about 2 yrs old... What you think about it, mainly the 2 things concerning,,,
1. SEEDING a compost bucket
AND
2. Also, I never drain my system anymore until the last week of flowering. In fact myself and many other growers that use compost tea in their deep water system save a lot of money in the long run because we never empty our our systems until we are doing the last week of flush. I just stay at 800-1000 ppm and top off until that the last week of flush.
