NEW Sunmaster 1000 watt MH conversion bulb. Works on a 1000 watt HPS ballast, and turns the fixture into a MH bulb for tighter vegetative growth and development.
Brand new in factory packaging, never used, never out of box!
Free shipping!
Made for magnetic ballast, not digital. Be sure you’re buying the right bulb for your fixture!
If you’re using a 1000 watt magnetic style HPS fixture, and your plants are stretching too much (growing too tall) under the HPS light, using this bulb for your vegetative growth stage will make your plants grow shorter and stronger, with tighter internodal spacing, and thicker stems to hold the plants up.
Increase your yield by growing a stronger plant!
