Mini split 24k
How much humidity an AC removes depends on how many watts you are spending. The more watts the more the AC will work to cool the room and remove more humidity. 24K is small if you are lighting the whole 250sqft. To light that you want like 8000-11000W on lights LED or HPS to light it. Which would need 11000x3.41btu= 37510BTU.
6x450x3.41= 9207 Btu
You’ll need a dehumidifier that would do the amount of plants in the grow you can’t go by square footage in growing. So how many plants and what medium?
Remember though ac units are designed for people comfort not plants they’ll never pull enough to properly dehumidify the area properly. Plus I seen a co2 burner in the background so that’s more heat coupled with his fans and everything else he’s going to need bigger. @thisbuds4u101 you need more cooling honestly man. You want it to run but not too long and not run enough. Both are bad on ac units. What are you using total equipment wise?
You. It's your grow. I did most of it for you. Just take all the watts in your room including fans pump, dehumidifiers etc. Multiply it by 3.41BTU/watt. And that's how much btu each device will produce. Then you want to size your AC to be a bit bigger so it can manage the heat load reliably while not working too hard or too little.
