Yeah my grow came out solid with the SF BUT (a big but) I knew what I was going into and had everything laid out properly. Heat was not going to be an issue (as I use a/c) and I had multiple lights to cover the ENTIRE top of the canopy. I am talking an sf 4000 and
sf2000 all in 1 4x4 section. I asked to review SF LEDS from them before but they never let me. I bought 2 sf4000s 2
sf2000 and 4
sf1000. I use them for many purposes but only for what I know they can work for. Even though they grew me fat buds, I won't be using them as mains in my lab tents anymore. I told them about making them dimmable before and they never said they were going to do it. I was trying to offer them help many times. Now after I bought all my lights, they came out with dimmables. That is enough right there to not want to use them. I guess I am not happy with the service more than anything. So, Grower's Choice and TSL rocked my world with their new e720's and now that's what I use in all my research tents and commercial grows.
