Gelato X GrandDaddy Purple - bubbler bucket

Been about 2 weeks since first root. Germination on Dec 1, roots hanging from pot around the 14th. Root growth is massive. Plant is starting to get first few branches. Probably still keep in the 1 gallon bucket when I do rez change. I’ve only had to top up once and everything is pretty stable. Ppm dropping slightly and a slight rise in pH each day. Been about 8 days since last change. I feel I can get a few more days. I added a humidifier on a timer and a seedling mat to increase humidity and temperature. Pix from Dec 28
