Yes I know it is for sure also. What I did was crazy overboard. On purpose. To me, rather too much (available) than too little. I did an
sf4000 and
sf2000 in EACH 4x4 space. Pretty much wall to wall leds. Now, you NEED to have dimmable lights to do this or you will seriously fry your plants. Although they were dimmable, I had the older model where I had to open it up and adjust it constantly which was a HUGE pita. Also the heat generated at the top of the tent was SO overwhelming, I had to use 2 dedicated 8 inch hurricanes to blow the top and a dedicated 8 inch
AC infinity in EACH 4x4 to suck the air out into the duct that leads outside. This screwed my CO2 circulation so I installed a heavy BTU split A/C and had to bump it to 2 degrees cooler than I wanted to balance the heat output. It is very difficult to get a good balance of everything that you need for the perfect setup. All I know is cutting corners or buying 'cheaper' products end up in more lost money and creating a whole slew of new problems. Since changing out my lights, I now have MORE par, less light heat, don't need a constant heat exchanger, not going through tons of 20lb tanks of CO2, and didn't need to have my AC pumping 24/7. Not saying SF is bad, it cuts corners (in order to cost less) that may create new problems. They fixed the dimmer issue, now fix the heat problem.
