Hi, I’ve done a few now in a rdwc system. Using some bio biz feed and organic rooting additive, , keeping ec low around 1 1.2 , atmosphere is good with good air flow heater regulator thing. I don’t change the water nuits every week though but still regular changes Also tryed using some hydrogen peroxide this time and other bits ,but roots seem to stop growing, but not rotting allways been having really poor results, I believe it’s something to do with roots as the allways go a bit brown, and seen to grow around the air stone , and tend not to grow after half way , this time they have matured really early to. Really appreciate any help please thanks
About the same as the room 19 20 , seemed to be like this when I used to use a water cooler in hot weather, water cooler gives of some heat though
20c is 68f. Those roots will be ok. As long as its under 75f . I think you should measure the water more often with a different monitor . To me they got to hot and rotted . This will not happen 20c
