absolutely need to do a strict wet dry cycle especially at the seedling stage. for seedlings you do need that cycle but make sure you don t over do it and leave them too dry too long, they hate that more than too moist. For seedlings and autos, VPD is very important : the vapor pressure deficit. VPD regulates the metabolism of the plant and the metabolism is the difference between an optimal grow and a slow grow. learn more here http://www.just4growers.com/stream/temperature-humidity-and-c02/vapor-pressure-deficit-the-hidden-force-on-your-plants.aspx ... try reducing your PH to 6 (what s the PH of rain water bro ?), and put a plastic see through cup on top of the seedlings to get that humidity right. spray with cal mag and kelp extract until dripping twice or three times and week and see for yourself ! hope this helps ! 🚀
