Do you add CO2 to your grow room?

Because. .just for the simple fact you stated co2 was useless with plants grown under led's . Plants certainly do benefit from co2 supplement from all types of plant lighting short of maybe fluorescents. Either you weren't using the co2 correctly or you were using shitty led lights. Possibly both. I know next to nothing about led lighting for plant growth. I Am an hid guy and have been for decades. But I do know there are more shitty led fixtures than there are good ones. Way more. The good ones are expensive and made by small little company's and all of the workers/designers are actual real world growers that know there shit with ppfd and all the lingo or the other good ones are made by the do it yourself crowd. But with the few very good and well thought out led lamps..plants most definitely see gains with co2 supplement. Fact.

I find it oddly funny that nobody will ask what brands we used to test out and keep banging away on the keyboard...
Regardless, maybe the word “useless” wasn’t the right word I should have used. You’re right.
The fact still remains that the HPS and MH lights out performed the LED when supplementing with CO2 in terms of plant growth. All factors were the same. All plants came from the same mother so had the same genetics.

...and awesome if LEDs work for some people. I don’t know any growers personally who have had the comparable results using strictly LEDs (compared to HPS) all the way through a grow, but I do know a few that use LEDs with HPS at the end of the flowering cycle and have claimed good results from that sort of supplementation.

You talking aquarium reef hobby type stuff? I have some pals that are into that big time. Cool hobby and wicked looking fish and reef coral.and underwater plants. I was always impressed by you reef aquarium geeks. You cats know what's up with that world. Heard it was even more delicate and expensive than indoor cannabis growing. Got any pics?

I'm into freshwater stuff, sadly my shit is a bit identifiable, been doing it even longer than growing weed.
Yeah, it is much harder, but it will provide you with a very hands-on knowledge of plants as you need to provide some things like iron, almost daily as it doesn't stay around long and can only go in low concentrations. You will also learn why knowing your water hardness is of more use than knowing the pH.

I wouldn't say crushing. Maybe single ended traditional hps lamps. Watt for watt and a skilled grower with a jamming cultivar and canopy...damn son. They do kill it. But double ended hps fixtures still bring the power. It's just that heat man. Them fukers are so damn hot. But I hear ya. Led's are in the game and here to stay. Just look at GMLs recent side by side throw down with single ended thouies (I think 16,000 watt worf) and the other room packed with a lil' over 8500 hundo worf of HLG 550's. Still don't know the final dry cured weigh in. Haven't checked up on his vids. But I assume it was close. Even if the HLG side got slightly less...damn man. Just over half the wattage? That's a game changer. The good led lamps don't play. Just spensive. $$$ on the initial buy in.

Averaging about 2.5 units off of 750 real from the wall watts? Holy sumbitch that's frikin bringing the real deal. Wow. Straight up destruction. Got any canopy just before chop pics?

You aren't even contradicting the statement you're replying to.

Yes, experience is worth nothing. I see you couldn't argue it has a value. Your inventions are worth nothing.
Your yield didn't increase. That never happened. Your yield claims are lies.
No, that's a fact. Right now, most of my work is weeding out old idiots slowing down companies to make room for people whose knowledge isn't outdated by 30 years. They usually hold management positions and refuse to accept new knowledge. Like you.

Hi, I need an expert's advice. What if I turn off the CO2 during early flowering(the stretching phase). Will it make the plants shorter? I'd like to know how to use CO2 to make plants shorter if it is possible. Thanks for every help.
Btw I'm with LEDs. I grew a Sour Diesel auto in a closet under CXB3590 at 50Wx16h at the end. 95g(3.4oz) dry, double harvest, w/o CO2.

CO2 will actually make your plants larger, not shorter. Assuming your environment is as it should be, extra CO2 (in conjunction with extra water, light, and nutrients) will produce extra photosynthesis, which translates into more growth.
Look into the various training techniques if you want your plants to be shorter. Both topping/fimming and/or LST will accomplish your goal of a shorter plant. Look into SCrOG as well, will keep things nice and short. SOG can do this as well, if it is practical for your situation. Or simply grow nothing but short/stout indica dominant strains and avoid the stretchy sativa/hybrid strains.
