Jef79answered grow question 5 years ago Hello.. Hope you are well.. Personally i treat my cubes like soil.. I use nutes then use water.. Always keep ph at 5.5-6..i also find they prefer to at room temp.. Not cold to the touch or the underside.. I simply place a towel under my tray to keep the cold off her roots.. I also always water from the bottom n let her suck up the solutions then let gravity drain any excess away.. Only quarter dip them aswell.. They suck n hold alot of water up(10x coco).. Water/feed wenever they feel light as with soil.. Ur girls look nice and healthy so ur definitely doin it right.. Stay safe n gud luck with your gardening activities.. 👍🍀
