Good thought, however, been there done that! My current GR dehumid. is about 20 years old. Works well, but puts off a lot of heat. Bought a new 50 pt dehumid. with digital controls thinking it would be more efficient, less heat, etc. Not. So, the new dehumid sits in the main part of the basement, set at 50%. The old (manual) dehumid. is in the grow room. Between the two of them, I can keep the humidity where I want it, but with a unit in the GR there's too much heat.
We live on a peninsular with water on three sides, about 300' from the water. The whole area is sand and the water table is around 12'. We have never had water in the basement, but waters levels are high this year and the basement is quite damp. Normally, temp runs 60-65 in the basement, but with the dehumid. running so much it's in the lower 70s. Even when the A/C runs. That's part of the problem.
