250 hps question

[Melnick]

What would be the distance from a top of a plant to a 250 hps ballast light. Thank you.

Well it all depends on how hot it is in your grow area. I would say between 12 and 24 inches away. The best way to check is by putting the back of your hand on the top of your plants. If the light is hot on the back of your hand then it's hot on your plants and will need to be raised.

I can manage 15 plants in flowering if its under 1000 watt hps, but for your little cute 250, u can do 5 plants or 3 plants with hydro/flowring only. sad huh hmm.... but not sad if you smoke it for yourself good luck!

A rule I use with HID's is to place my hand at the top of the plant canopy, and leave it there for one minute. If the back of your hand becomes warm, raise the light slightly to a point it's comfortable. As the plant grows, maintain this distance. This has worked well for me.
Hope this helps...B
