Measure the length and width of your grow area. Multiply those numbers together to get your square feet. a 4x4 area can be done with one 400 W HID system. a 7x7 would probably take two 400 W or one 800 W. The more wattage the higher the temperature. Make sure you get good ventilation or a fan system setup to help cool it down. I use one floor fan set to low blowing constantly right on the plants. That ballast looks decent but make sure you get lights with it. Those can end up costing as much as the system when they are not included.I think the best thing would be a switchable ballast HPS+MH, but how many watts......I believe I calculate that by my grow area?
can I get some information about selecting the correct watts, I might have ten plants by the time I buy the light system, im sure you calculate the square footage of ?
the plants, containers? what
thank you
As for your PM question it dosent matter which way you plant the seeds. The root will always go down in the soil and the top will go up. The plants have it built into their DNA.
Good luck and happy growing.
