Watts per sq ft. How many watts in your grow space

[Hypathetical Gardener]

In my 4x4 i have a 315w cmh.
So 19.68watts/sqft
I have 2 leds in my 2.5x2.5 tent. Each pulls 130w from wall.
So 41.6watts/sqft.

31.25 in the 4x4 flower tent and 30 on the 4x1.5 veg racks. All Bridgelux EB gen 2

12 auto cobs in a 4x8. 8x 3500k 4x 6500 k. Thinking about putting 4 more in there. 2 on each side.

My space is a 32x32x63 inches. I have 3 autcobs 55w each.
3000k
3500k
4000k
So total 165w
I guess if I'm doing the math right around 21 watts /sqft. Someone correct me if I'm wrong.. :smoking: :smoking:

In my closet which is 2x2x48 1 spider farmer SF-1000 pulling 93 watts, 1 65 watt hlg qn pulling 65 watts and 1 2700k auto cob pulling 54 watts but that's for flower only. If someone can help a brother out with the math it'll be much appreciated!!

i do 250w + 300w (LED draw from wall). So about 550w in a 4x4. Mars SP250 + Mars TSL2000.

About 35w per sq ft.

Logic tells us that humidity, light spectrum, temperature, air circulation, CO2 level and strain will have a huge impact on how intensive light the plant can use. I think the plant can use more than 50 watt per square foot blurple with a lot of red and no IR. IR is heat and the plant don't need it if room temperature is well tweaked.

475 (dimmable to 245) cob watts in my 3x3x7 flower tent. So about 52 cob watts per sq ft at max
