Adding my two cents for Timber and heat. I am in San Diego, went to Timber direct to pick my five up. 4x4 tent. They have been adding about 8-10 degrees to my 4x4 tent. I changed cycle times to limit early/late afternoon heat here. I almost went
HLG 550 board but I wanted to use a local company in case I had any emergency issues I could cut out shipping delays and possibly get loaners or something worst case scenario. I bet a board gives off about the same heat as these Daisies do though. I grew (4) nice BIG 5 gallon fabric pot Hashberry gone male mid flower and turned those balls into a big pile of gold kief dust. Overall though, the lights are fantastic. Round 2 with them started a few weeks behind you.
