Im starting my first indoor hydro grow and I need some advice on ventilation. first do I want a fan to blow air on my light and then a seprate fan some where else for exuast. or do I want the fan to suck the heat from my lights and a seprate fan blowing in air some where else thanks
Hey, You want to draw hot air out and cold air in. So out take on your light (up high), and intake (down low) somewherelse.
Thanks first time growing indoors so this ventilation stuff is all new to me. the fan i have sure pushes out a lot of air put i dont know how good it will be for sucking hot air.
If it does one, it should do the other, just depends on how you position it. For better effect, you should have one for intake, and one for out. Make sure you position/mount them so they cannot move, or fall.
