Anybody use this system dwc drip sysrem

hi anybody use this type of system it is a 6 bucket dwc drip i was thinking of buying one but i'am hesitant because i have read that the water sitting in the buckets dosen't circulate and tends to have temp problems any info would be great

there are many systems like that. its fine to have water sitting in buckets as long as there is an air pump in there (in any dwc). the rdwc systems dont let water sit in the buckets, but are connected by tubes at the bottom of the buckets, and are fed by tubes at the top of the bucket, and generally all flow into a res bucket, with the water pump sending it back out from here. easy to make. i probably wouldnt buy one cause they are hella expensive.
temps should be less of a problem in this kind of system than an ordinary dwc with no circulation.

also above 75 degrees rootrot will occous due lack 02 there are re cycled dwc systems this way u ensure great temps
