At this point should I be watering with my little spray bottle or with a full on watering can? I've heard many conflicting things about which is better
When mine were this size I would do about 2-3 shot glass fulls every night right at the stem to force the taproot to grow down instead of out. Then I lightly misted the other soil as to keep it from all getting to dry under my lights. Looks like you got a humidifier so that's all they should really need man! Happy growing!
