Importance of a CO2 controller

I think the majority of folks with CO2 input will be in the advanced section, might want to repost this there. Many of those guys don't venture to the beginner or indoor sections

 

No we just lurk the beginner sections.

Without a controller you're jsut gassing the room, and possibly venting it all over your house.

 

sorry for a really dumb question.but when is it best time to use CO2?veggie?flower?how many times in 24 hours?feedback would be highly apreciated

 

All the time.

CO2 is like nutrients, the plant always needs it but only at a particular level.

You would use the controller to ensure the ambient CO2 is dialed in.

 

does anybody know any good threads for CO2 usage?because i have a full tank and if its good to use than ill use it but i want to know how?when?how much? +rep for a good thread or a good answer.thanks.

 

That is not true. CO2 should be turned off during the dark hours when used with flowering (Few augment CO2 in veg rooms). If you are using it with vegetative growth, then it can remain on at all times.

You cannot accurately estimate the PPM level without a meter. My buddy ran gas on one of our tents, but didn't buy a meter. After harvest, I took the tank and put it in my tent. Same tent model (DR 240W)... I ran the gas at the exact setting he had it on, with a timer on the regulator based on the calculations he made (the math was correct), and found that he was only bringing the gas level up to around 600 PPM. Far short of the desired 1500.

You really do need a GOOD PPM meter. I've been running two C.A.P. PPM-3 units, but they are completely pieces of shit. DON'T buy one. The wire connection is completely unsupported, and the weight of the wire pulls on the connections and eventually causes it to fail. It ends up not turning off the gas when you hit your set point, so it just keeps burning (or bleeding) your gas. Sometimes it fails to read the correct level too. it will stay stuck at 600 PPM even if it is really at 5000 PPM in the room. This can actually be dangerous in a home grow. Some people get ill and dizzy from high PPM levels. Also, if using a burner, you should have a good CO monitor and alarm.

I just received the Sentinel Digital CTC-1 environmental control meter in the mail. I have not had a chance to instal it yet, but I'll be reviewing it this week sometime. I'll have it installed tomorrow. It looks to be a MUCH better unit than anything CAP makes.

I was able to find this unit, unused, for $450 on e-bay.

 

get a controller, plants at different stages absorb co2 at different rates, so using a calculator based on room size is extremely inefficient imo and a waste of co2
