Recommended Height for HID 400
What is the recommended height above seedlings for the above listed lamp? Help?
It is best to use (cool temp) fluorescent bulbs hung right above seedlings to get them to sprout and get a good start. The light needs to be intense and bright and close at that stage (HID is too hot to hang close enough). You can find really cheap fluorescent lamps at Walmart or builder supply.
The HID is better for use during growth stage as described here: (see the chart): HID Lighting
Hope this helps, Howard, and good luck to you!
