Youthmananswered grow question 2 years ago Hello! I'll start by saying that it's better to have the substrate perpetually moist rather than an alternating dry-too-wet, so you can opt for a timer that goes off a few seconds every few minutes, just to have constant moisture in the substrate. I usually use rockwool , I prefer it over other types of hydroponics because it maintains pH better. (Dwc for example 5.5 the best) By the way, 6 is the best range in coco, and 6.3 in soil. For pH, you can opt for a continuous phmeter , a hydrostatic pump that monitors and keeps pH constant.
In rockwool im using biobizz products, i love them and i dont check pH ✌️ no problems in 20 days old, with dwc i had to check every day
