Well... efficiency might imply the highest yield per watt used? So I would venture to say... you'd be better off with the light mover. It uses almost no electricity and will be guaranteed to increase your yield without increasing power consumption.
If power consumption is absolutely not an issue and only max yield per sq. ft... 3x 600s in a 4x8 will be SICK. You will be able to pull some weight from that tent. Have fun!
Well, it's going to be almost double your original power consumption. If you want to keep the bill about the same I'd stick with two 600s on a mover. But if you can pay the bill, 3x 600s definitely isn't enough to be sketchy in any way. For me, here, I'd maybe pay an extra $15-$20 a month on electric for that extra 600 at the most. So, it would be worth it, to say the least.
Milehigh - This will be my first time growing in the Homebox XXL. I have been growing in a 3.5x3.5 closet with 1000w Hortiulux with 6" Radiant Hood, 14 Site ebb and flow vegged around 7-10 days LST'd just a bit. Have been pulling between 16-18 OZ. of DP WW every time. Just looking to expand and use my new lumatek 600's
A few months back I added a 600 to a Small Homebox and the bill only went up 20-30. I am now the only person living at the house instead of 3.... It's on like donkey kong
is it easy to set a mover up in a tent? i run 2 600s stationary in a 4x8 currently and would love to tweak it or add a 600 myself. good shit heads. peace and smoke
Curious as well.how many plants are you running in that 4x8 tray and how much you yielding with 2 stationary 600's.
