This is not really a question from me. It's more of an observation. I'm looking any opinions.
Grow tents.... fixtures INSIDE.
Two fixtures compared >> An LED fixture (VIPARSPECTRA PAR 700) and a HydroFarm 315W CMh (LEC) fixture.
The VIPARSPECTRA PAR 700 specs show that is consumes 326 Watts.
The HydroFarm CMh specs show a 315 Watt consumption.
326 Watts vs 315 Watts..... close enough for me.
The VIPARSPECTRA is a self contained unit. The Power Supply and drivers are inside of the fixture. Inside of the tent.
The HydroFarm 315W CMh has and "external" Power Supply (Ballast) which can be place outside of the grow tent.
Since the VIPARSPECTRA has all of its internal power sources confined to the fixture, then all of the heat generated by its 326 watts will be introduced into the grow tent.
Since the HydroFarm CMh has an "external" ballast which can be placed outside of the tent, then it would seem that the HydroFarm CMh fixture would introduce less heat into the tent.
So far, I have seen that the VIPARSPECTRA LED adds a LOT more heat into my tent than does the HydroFarm CMh setup (external ballast). Not scientific for sure.... so keep an open mind.
