Just a heads up.

NGW has began distributing new tube with no packaging and no writing on the tube what so ever. I have not had a chance to have it tested yet, I just received a new roll yesterday. But be on the look out. I would only use general hydro or hydro farm since those are both marked and has been proved safe.

Every thing that went into one of my 11 different rooms (some that had been going 5+ years) started to yellow and eventually die. My first instinct was my ph I checked my pens, they were not very far off but I calibrated and bought new probes anyways. That did nothing. Then we suspected the nutes, maybe we got a bad batch. I had bought 6 gallon jugs and filled all my 1 galā??s up off the same batch. Call the company run Rating: 5
