Just got back from Holidays and my plant got mucho bigger! Only left a cfl on it and it found a way to burn itself. Cleaned off some white fungus. hopefully it isnt bad prob from lack of airmovement.
pic from phone sorry
you can start in rockwool until the roots come out the bottom and just fill up the tank, maybe more than suggested if you bought it from a store. otherwise just water it yourself, or dunk it in the solution every few days ....
i hear that the blueberry has a tendancy to not flower automatically, and also strain is not stable ... at all. but hey take a huge risk your first grow..
