During my fight against root aphids I decreased my room to a 2x4 tent with all my plants in rockwool cubes. I was given two bottles of sns 203 to try I added them to my flooded 2x4 tray. I tipped over every plant so it was completely submerged for maybe 15 minutes came back and drained the tray. All I find is dead ruptured bodies. We have dissected several blocks and have found no evidence of living aphids. I think its a great product. If I could figure out how to upload pics I would show you my ra eradication process.
