How does watt affect the growth cycle?
For a smaller growing operation, lower wattages are needed. For larger growing operations, it is best to use higher wattages that can accommodate more square footage. The wattage is the intensity of the light produced, so larger plants benefit there. But height placement of the bulb is also important, as height helps allow for taller plant growth. It also produces less heat, so plants don’t burn.
What are the different watt settings for -- and what type of bulbs can I use with them?
On our ballast, we have four settings of 40%, 60%, 100%, and Super Lumens (110%). Our Pro 1000 DE digital ballast can use lamps with 400W, 600W, and 1000W. Note here the most efficient way to use watt settings: Match the wattage of bulb to the same wattage setting on the ballast. The lamps are designed to be the most efficient with its corresponding wattage. For example, a 600W lamp set at 100% on the ballast would be more efficient than 1000W lamp set at 60%.
Our Innotech Pro 1000 can be used with any 400W, 600W, 1000W double-ended Metal Halide (MH) lamps, as well as with 400W, 600W, 1000W double-ended High Pressure Sodium (HPS) lamps. As you go through the various stages of your growth cycle and find the need to change lamps, you simply do so as needed without having to change or move the fixture.
How many watts per square foot do I need?
In general, 30-50 watts per square feet is optimal. For example, a 4x6 tray would be 24 square feet. This means it will need roughly 720-1200 watts.
