Just got a 1000W MH

trace00969July 29, 2007

So I just went and bought a 1000W MH with the reflector for under $300 canadian. How far should this light be from my plants? Right now I am only using it for a 2'x2' areas, I know I can go bigger, and I plan to. I use it mainly for hoyas and foliage plants.....most of them are quite small, so once they gain some foliage, I will move them into windows. Right now I have the light about 2 feet above the plants. The heat isnt really a problem since I have a 12000 btu air conditioner going in the same room.....My dining room has turned into a grow room.....lol.

I would love to hear any tips on using this light, its pros and cons and anything I should watch for. This is my first HID light so I want to do it right.

Thanks

Tracy

Wow, overkill! The 1000W light would generally be suitable for covering about 25-50 square feet, more on low light plants.

Two feet from the plants may be OK, but it will depend on your reflector. Watch the plants carefully the first few days and move them further away at the slightest sign of crisping on the leaf tips. Also watch out for wilting, I'm guessing the plants are not really used to intense radiated heat and light, they may take some time to adapt.

See how they do at 4'. Two feet from a 1000W light could be really quite toasty. It could also bake away the humidity the plants need.

A lot of people use lights without the tempered glass safety shield, but I would use one, especially if the bulb is within reach or might be reached by some of the misting spray.
