Under canopy lighting

[Indy]

Only ever had 3 infestations of gnats. Two in DWC and just recently in a coco mix. Been fortunate to deal with them effectively on all three ocassions with method i mentioned previously. Initial hit with mosquito bits, followed up with a hydrogen peroxide for a couple weeks.

You guys might be right. The dunks/bits might be shit and it's actually the peroxide taking them out.
