Better Breathing
I have a sealed room with CO2 at 1,600 PPM and I need to know
what level or additional oxygen is needed to have an optimal
growing environment?
Thanks in advance,

Ahoy Captain,
Adding CO2 is a great way to boost yields, and a sealed environment
is ideal for CO2 supplementation. Regarding oxygen, you are probably
already adding it! More specifically, your plants are giving off oxygen as
they take in CO2.You may add oxygen to your reservoir, because the
roots perform best in an oxygenated environment. Oxygen bonds with
water via air contact. Keep water moving with a circulation pump and
add beneficial bacteria to your system. As long as your water temperature is within the ideal temperature range (58 to 72°F), movement
and bacteria will take care of the rest. Just keep in mind that your
plants will take in CO2 and expel oxygen through the leaves. S
