are they a good thing? just on my first grow with these autopots using coco . northern lights. Got ten litre pots but only filled the pots just over half way when potted them. does anyone know wether i will be over watering them ? they are about there about 20 inches tall quite bushey, been in flower a week. someone i know had great results with the 7 litre autopots tho . But i got these cheap just need to know if i have done a stupid thing ,only started the system two days ago because i snapped the filter and had to wait till arrived before i could get on the go. and they took about 25litres of feed in one day. i dont know wether to stop the system and hand feed instead but not got much time on my hands
