I have one issue that's troubling me and I keep flip-flopping on which way to go.
It seems that an air-cooled hood has the advantages of being able to keep heat down from the light's output, increase bulb life, as well as allowing you to place the light closer to the plants. The negatives are that the glass in the hood can cut the lumen output by up to 10%, and also having air move across the bulb can cause a voltage drop decreasing light output even more, up to 25% total loss of lumen output with this setup.
With that being said, wouldn't a grower be better off by controlling the temperature in a tent (for example) with solely a powerful speed controlled fan maybe in combination with controlling the temperature in the room, outside the tent? Of course you'd use a batwing or some other type of simple reflector instead of an air-cooled hood. On paper this seems to be the best way to go but I could be completely wrong, that's why I'm asking. Thanks.
