Questions about Climate Control

What humidity should I keep?

It depends on the plants and their stage. Steady airflow keeps heat and humidity from building up, and a controller with a humidity probe holds it where you set it. Read the guide

Dehumidifier size for a 4×8 tent?

It depends on how many plants you have, how much you water and the room around the tent. Compare the pints-per-day rating of each model, or call us and we will size it with you.

Do I need CO₂?

Not for most home setups. Get lighting and ventilation right first; for commercial rooms, our Commercial package includes CO₂ and controls.
