Alright mate, Just been looking over you system again and the other post you link me to and i have yet another question lol.. Do you draw the water back to the control via a pump or do you just pump the chilled nutreints back to each tote and this sends the water back towards the control.. so draw or push?
I just pump out of my control res on this system, gravity and my big drains do the rest. If your flow is too much for your drains youll fill your buckets. but youd need really small drains or a massive pump. stay with at least 1.5" imo
2" min in my opinion
i did 1.5 returns and 5/8 heater hose to the totes but bigger is usually better. i centered my drains in the totes which i felt helped keep the roots out of the way better than on the sides.
Also, you need to chill the entire system via a small pump rated for the GPH of your chiller. The waterfalls need to be on a decent 800-1500GPH pump if you want the pressure and spray needed to get that good good aeration.
No drain so pumping for that is my only option at the min.. but cheers for the other info.. can't wait to get building.
Was wandering about that think my chillers max flow is 2500ltr/h so yeah looks like 2 pumps.. and maybe a chiller upgrade aswell soon. Great info thanks again
I've put 2400 GPH through mine and the water level stays fine it's just that my chiller doesnt keep up. I've had the 2 1200gph pumps turned down, I have 800s on the way to replace them. Itll have around 1600GPH for a 90 gallon system which seems to be working well for me.
before you upgrade your chiller, you can try what i did that worked fine.
I found that my 3/4 heater hose had an affinity to let shit and film grow on the inside. I think it had something to do with the texture on the inside of the hose. I would not use heater hose again. I would go for something vinyl with a smooth wall. For what its worth. Just something to keep an eye out for.
heater hose as in what goes to your heater core in an car? what i used was smooth walled black rubber maybe 1/4" thick roughly.
The chiller is rated to about 300 to 350ltr so not to big.. Will look into the wort chiller but i thought with these chillers being titanium inside I didn't think the life of it would be shortened by putting nutrients trough it?
