My next grow will be in a 5x5x7 tent. I have problems with my circuit breaker so I need to use the least amount of power to fill this tent with light. My solution to this will be to continue using my 400 watt hps. I will also have two area51 RW-75 on each side.
This will cover most the area; however, it won't be enough. Therefore, I will be adding four cree led a21 bulbs from Home Depot in each of the four corners. The cree bulbs are 30 watts each. This will bring my total wattage to 670 watts.
This will be a fun experiment for a led/hps combo.
I will also be going full organic because I have had soil cooking for 3 months now. No more fox farm as I currently have 3 fox farm plants and 3 organic. 5 or 7 gallon fabric pots.
