What do you think pop? If I could tune this a little, I think it would be a good way to grow in smaller pots and still have the benefits of auto feeding. I think if/when I try this again, I will add more slots in the bottom of the pots to maximize feeding.
@2Stoned2Care noticed some underfeeding and I think that may be why the buds aren't filling out. Other than the lower leaves, the plants seem healthy enough, plenty of bud sites, just not filling out. Another issue would be root control. May have to get some discs and modify for smaller pots. Any observations?
