Dry grams per square foot

I've grown mostly in an 8x4 but I added a 2x4 this year. It's actually my Auto tent now but the 1st grow was 3 photoperiods, Rainbow Belts x Okie, and with SCROG in 3 gallons and SIP system (bottom watering), I was able to pull 69.18 grams per sqft. I use a Spider Farmer SE4500, older model with 430 watts and 4 light bars. I also use their UV, IR, and Deep Red Supplement Bars. I put AC Infinity Ionbeam S16 full spectrum supplement bars at the bottom of my tent and shining up, this made the lower buds develop more and weigh more.

"HPD" = HPS, oops

Most things have to go right to do 50-60g/sq ft. Using clones of a strong plant can help greatly. I just had a herm, so 1/10th of my canopy just went poof. I have a weak plant that's not going to pull it's weight too. My yield is down at least 15%, and it's still several weeks from harvest. Maybe 1 or 2 more don't form the type of buds i expect... Don't overcrowd. Only need about 3 colas per sq ft. With a sog, are you filling the space or is it crowded? May need a couple more plants. If a sog doesn't grow tall enough, you lose depth on canopy which could impact yield. Don't defoliate without good cause. if i recall you are big on that from other answers to grow questions? Leaves are supremely important. Even shielded leaves are value-added. it's a myth that somehow cutting off leaves allows the plant to focuse more on flower or anything else- this is simply wrong on all levels and not an opinion up for debate. You can definitely get an lb out of that tent. a (2) 2x2 plants can be 200-250g with the right genetics. DLI is DLI.. it doesn't matter if it comes from spiderfarmer or HLG. there is no different quality of light. Especially nowadays with full spectrum lights being nearly identical across PAR wavelengths. There is higher efficacy and that will directly impact g/watt metric. High efficacy lights can hit 1.5g/w and upwards of 1.7+g/w in ambient CO2 conditions. If you use an HPD, you barely get 1g/w if you do things well but same grams per square foot production. Low efficacy lights shouldn't impact yield, assuming the extra heat does not cause a problem. If a light has a high price and mediocre efficacy, it's over-priced trash.

Im getting a quarter pound + a plant off a 4x4x6something ft tent with 2 900 watt viparspectra but my buddy runs an ecg growtech. That thing is next level. Your basics are solid food medium climate, id say light is the thing to do and yeah your sog method should keep the ladies at bay. Pick the right strain. Your growing beauties man. And if you do heightxwidthxlength your figuring cubic ft.

I'd go more of watt per gram more then area per gram. So if I'm running 100watt led I'd be happy with 1g/w which is 100gram. 200w=200g.

I only have a 1x1 with 300w growing in soil (supersoil) without co2 I do 300-400 grams per cycl

40-50 is not bad, that means in your 2x4 your getting 320-400g of dried product. that's nice. I find indoors stuff is always smaller but normally much higher quality vs outdoors. You can also ditch the tent and just hang lights and white sheets up, but the room will stink. Maybe a SOG would be good as well with a bunch of clone cuts keeps em low and fast turnover. one main cola each. experment, see what works for yea.

I had few attemts with very limited conditions, 3 plants, soil, auto or photo, always 300g +. In coco and better ventilation i think 70-100g/ could be achieved...
