We swapped to Active Aqua Grow Flow buckets from DWC. Much easier to mix one resevoir and have it feed the buckets automatically vs the DWC setup. We now have a hybrid Bubble Boy DWC and Active Aqua system lol.
Anyways we've been experimenting with some supplemental lighting with LED and already seeing results. Lots of development underneath, super bushy, and thicker stalks than the ones without supplemental lighting in the back. Can't wait for the later flower weeks.
Quick question about your DWC, do you find that salts and sandy material still remain in the bottom of each bucket even after changing the water?
I use a 5 gal bucket system like that but find it leaves a lot of crud on the bottom and I end up shop vacuuming each bucket out anyways.
