CO2 Implementation

[Gutlez]

I was curious as to how much CO2 to implement on auto flowers. I’m using a Spider Farmer SF4000 LED

Is it based off the light of how much CO2 they will take? I’m just trying to maximize my yields with the lights I have.

thanks for anyone stopping by.

CO2 is a hot topic when you're not running a completely sealed room. With the intake/exhausts that most growers have in place, it's difficult for CO2 to be effectively contained and utilized in the space (meaning it's often just wasted/exhausted.) With normal proper air exchange, your plants should have plenty of CO2 from the atmosphere (which runs around 400 ppm average in most places) without needing supplementation. Further, CO2 is only one limiting variable in photosynthesis, typically higher intensity lighting and other environment considerations need to be made for it to even be utilized.

Just my two cents, but most home growers can skip the CO2 supplementation.

As Son of Hobbes says, co2 supplementation does little to no good in a vented tent.
Also, my co2 meter says those exhale bags don't work.

To implement co2, a mostly closed system must be used, which could cause problems.

A different method of increasing yield is to use the high humidity recommendations of the Vapor Pressure Deficit chart.

I do have a completely sealed room for my autos. My question is, would I benefit from adding CO2 with a Atlas CO2 Burner? And how many PPMs would be good without just wasting

Unless you have worked out all the kinks in your runs, and you are on your A game as a grower... there are better returns to be had getting those things dialled in. CO2 is for when there's no other things you can do to maximize returns, then they can add weight. It's an expensive boost, requires special attention and care. (Running sealed causes issues of its own... skyrocketing temps... rH will need to be controlled...

You can see up to a 20% increase in weight.... but... 20% of what?
Learn to max out your area first, so you have a good understanding of that # is and how you got there.

If you need a weight increase, run down your system, and maybe we'll spot something that will help.

Assuming you can get everything else dialed in, 1000 to 1500 ppm CO2 during lights on are good targets.
