Hello LEPPY LE PEW

If you are going to go HPS... don't waste your time with anything less than 400watts... and recognize that HID lighting is only effective if you can manage the heat..

meaning----- draw the heat away from your plants so that you can keep the light close to your ladies.. (no further than 10-18 inches)...

it is easy to manage the heat if the plants are in an open space.. you can simply use a regular house fan and point it upward towards your light and blow the heat up and away from your plants...

But if you are growing in a confined space you will need an exhuast fan..

and NOW you KNOWM
