Hello family started flowering and I got a question for you. I am. In A 4x4 tent and was thinking about adding. CO2. I am not sure if I should. Some people say yes and others say. No. But no one is willing to help pay for. It. I can turn the filther fan down. Inorder. To keep the co2 in the tent the next question is I'm going into week 3 of flowering is. This the best time to put the co2 in thanks for all your imput

You can use Co2 straight through the entire grow pretty much...best way to keep the Co2 in the tent is make sure your extraction fan is as high as possible and that the air being sucked in is also up high...run air tubes around the tent about a foot below the intake height. Since Co2 is heavier than o2 it sinks...this will keep more Co2 inside the tent. It won't prevent it from being exhausted at all, but this will keep the most in there while you are running your extraction fan :)

Thanks massha.I have a 1000 Watt blockbuster with a 6 inch fan with it's own speed controller. And another 6 inch fan with controller on the filther

CO2 in a tent is absolute bollocks, if you want to utilise CO2 then you need a sealed room as plants don't need oxygen to grow. There's no need for air exchange, only extraction of heat from the lamps (cool tubes and ducting!)
The CO2 bucket thing and yeast/sugar is also bollocks.

Carbon Dioxide levels should be high, particularly during the FLOWERING PHASE . Growth rates can be increased dramatically if the CO2 level is near 700 ppm. 300 ppm (Outside Air) 700 ppm (Ideal) 2000 ppm (Plants Burn) 5000 ppm (Death)
They charge £200 for a CO2 sniffer for a reason, there's no way you can get anywhere near 700ppm from a CO2 bucket and it's laughable to think you could get it from yeast/sugar!
Most guys who run a sealed room shoot for around 1200-1500ppm CO2.
It's pointless messing with CO2 unless you've got your growing skills dialed in 100% and you can't get any more from the strain your working with under normal conditions.

Does co2 really make a massive difference?

Yes if you do your research and set your room up right first time, 30% increase in yield is easily achieved with CO2 and a sealed room. Advanced growers can double their yield apposed to regular growing.

All the photos that you find when you go to buy seeds - are of the weed grown with CO2 - because when you grow it the normal way - buds just aren't that fat or that coated with Crystal :(

I'm sorry but your wrong. And to prove it here is one of my "Sensi Seeds Skunk #1" from last year.

Fat.

Grown in a 9 litre pot of Coco under a 400w bulb, no CO2.

I wouldn't grow without co2. The growth rate is quick and your more likely to hit the g/m2. you can run temps into high 80's, only exhaust to bring temps down and extract moisture.
