CO2 Enrichment Requirement Concerns

Hey! I’m reading that you should have at least 7500 lumens per sq ft to really take advantage of CO2 enrichment. In a 4x4 area, a 1000w HPS has sufficient lumens (9375 lumens per sq ft) but not a 630w CMH which has less than half as many lumens (4125 lumens per sq ft) even though both lights are capable of producing similar yields. I’m just wondering, even though a 630w CMH has such a lack of lumens, quite a bit under the minimum amount recommended for CO2 enrichment, could it still rival the 1000w HPS in taking advantage of the CO2? The same way it can produce similar yields? Or it wouldn’t make much sense to combine a 630w CMH with CO2 enrichment?

Thanks!!

A 630 is fine for a 4X4 area.... A 400w would work. I don't think you want to coola 1000w in a small 4X4 area.

Have you sealed you room completely? C02 is a waste unless you do.

Also no one talks in lumens per sq ft. Maybe watts per sq ft

Co2 is not really worth it for a home grower "in my opinion", and can be dangerous. If you don't have the plants growing in a completely sealed airtight room the co2 will be wasted.
