Just ordered 2 mars hydro 300w. And I'm wondering if you guys recommend a tent or just mount them in the closet? The closet is about 3 feet wide, 6 feet deep, and the roof is slanted ( the closet is underneath the stairs ). Also I'm wondering if anyone else had a significant increase in heat using these? I'd like to keep this space as stealth as possible, so I would like to avoid large noisy fans. Thanks, Clayton
