I added yet another 150 watt HPS. Set it on chain about 10" from tops of planets. One ofthe plants today showed stress. Some of the leafs that would get a direct hit from this new add light were wilted. I backed off the light another 10" bring it to about 20" Also the temp in the area is a steady 76 F. Also I gave the plant a misting of water to help with the wilt. I am running 440 watt HPS and 160 watt flor. Am I on track? BTW I will shortly drop a photo of a plant I did couple of days ago..the axials on this one have really gone crazy..there has to be 200 axails and they are starting to grow out from stem.
