What yield do you pull from a 4x4 ?????

Not sure what you are referring too but if it’s earlier, than most likely it was from my first grow of orange gasm. The pic above is my second grow of sweet zombie.

3 pound or 1 pound really means nothing without taking consideration of the time it took. The longer the plant grows the higher the cost per gram of the harvest

If you want to max out the potential of your space work on grams per day per square foot. How many grams did you pull divide by the days from start to finish divide by the square feet of your space.

If you can get it above 1 gram and you know your shit.

Your calculation is incomplete unless you account for power consumption.

Nicely stacked tent mate. Is that 3 X 250 watt SF units?

One side is stretching a lot more than the other. Are you running 2 different strains?
Crazy isn't it they are the same strain?
I got GDP from ILGM and this is from the same lot.
My next run will be clones from the back right, it is beautiful shaped and compact. It is also very even in height.

I got one SF4000 and three SF 1000 in here hung in this fashion

How close is the light to the ones on the right? Man talk about stretch lol. Looks like those will be a super easy trim job. Should be a good yield if they fill in thick.
I got these lights about 6" from the tops
Buds seem to be doing alright. I know they would be frying if I didn't have additional CO2
It is a little bit of an optical illusion in this picture. As the sf4000 is actually completely behind the front right plant.
So the sf4000 is 10" above the back canopy, and I have a sf1000 above the front right plant that is 6" above the tops
Another week and I'll give her another round of defoliation I think

Anything can happen when your growing from seed. 100 percent homogenous seed is a bit of a myth. Any seeded plant will give it's offspring natural genetic variances to ensure it's continued survival.

CO2 is something I've been looking into. But I think to make it worth it you need to go big with burners and control units. Is your tent sealed? What are your temps and how do you deal with heat in a sealed tent. Do you dump the CO2 during lights off and cool the temps?

Cheers

I use two environments for my system.
I have a sealed 12x12 room, with a 4x4 tent.
The 4x4 tent has my co2 monitor (which measures co2 level in the air, turning a solenoid on and off connected to a 20lb co2 tank) i have 850 cfm of exhaust on the tent with carbon filter and 400cfm intake.
The sealed 12x12 room then, is also enriched with co2, but this room contains my dehumidifiers, and dual hose AC unit.
So to control temps and humidity in the tent, I adjust the ambient air in the sealed room around the tent.
The monitor i have also turns the CO2 off at night so there is no need to dump or vent.
I also have a AC infinity system hooked up for early veg, that way I can keep the tent warmer (I have LEDs which dont produce much heat) by having the inline system off when it doesn't need to be on.

No need for big burners unless you got a really large space.
20lb CO2 tanks are $30 refill and last 2 weeks at the peak use for me.
I just keep two tanks handy so I really only have to run once a month

Nice work. Sounds like you have it all figured out. Running this style setup would have to the easiest way to run a sealed room and control the temps. You would still need to run an exhaust out for your AC right? unless the compressor is outside

The dual hose AC uses external air to cool the radiator fins. This means no air is exchanged in, or out of the room using this style. This gives the best chance to conserve CO2

I thought that all AC's required some kind of exhaust to vent the heat which has been exchanged. What is the model of the AC? I'll look into it.

Cheers
No, to my understanding there are separate systems.
Single hose AC systems use air from indoors to cool the radiator, but dual hose entirely use air from an intake hose, then exhaust through a second.
Some window AC units can do the same

The dual hose AC looks a lot better than the single hose units they sell in Oz. Seems this style of AC is not sold around here

Hope this isn't too crazy if a bump, I got here via Google (it's not that old if a thread but don't know how buried it is). .

How many led watts can I put into a 4x4 without co2 before I'm wasting light about? 600 watts? 800 watts? 1000 watts? I'm asking power drawn from the wall not the bs marketing numbers.

I know asking for watts is not really fair.. but I dont have a par meter so bare with me and do your best.

Tbh I'm considering filling a tent with cheap 100 and 200 watt quantum boards.. seems cheaper than buying a $600+ light, that and I already have 600 watts worth still leaving my 3x3 with a couple hundred watts for veg.

Probably around 450w is a fair number for a 4x4.
If you get a light with amazing ppfd map, maybe you could run 600.
After that you really are not utilizing all the light.
