Okay, for all you experienced growers out there, what do you think are the best growing lights for closet or shelf growing?
I was always told high pressure sodium in all of its forms are the best to get. I recently bought a set of metal halides and fluorescents and both appear to be great. I have my 50 watt fluorescent 2 inches above my plants and my metal halides on either sides. It's working out great! I love to peek my head in and see the dramatic progress my plants are making with more efficient lighting (I used to use 15 watt Fluorescent only!). I'd say there all good for the correct purposes.
Metal halide or high pressure sodium? If you believe high pressure sodium is indeed better, please tell me of your experiences! |

Generally MH is used for vegetative growth, HPS is used for flowering. You can buy ballasts that will allow you to switch from MH to HPS, these are good for the closet grower.
The main problem with using MH and HPS lights is the heat, they get very hot. In a small space they will heat the room up to a temperature that will stunt the growth of your plant. If using either of these lights in a decent wattage (400-600) you should be venting the hot air. Try and keep the room around 70-80 fahrenheit, humidity should be 40-60.
Be careful how close you get them MH lights to your plants, to close and they will burn. You'd be surprised how much a plant can grow in 24 hours. |

Thanks a lot Raven, I'll keep that light distance very much in mind  Do you know of any ways to raise or lower the humidity in the specific area? What about the PH of the soil? What could I do to keep my soil at a decent PH level? I don't want to make a new threads for these subjects because I know there must be a very simple trick to each that doesn't require much discussion. Thanks again. |

| You want the PH of your soil to be around 6-7.5. PH can be lowered with vinegar, as for increasing PH I've always just used a PH increaser I buy from the garden supply store. |

How do you apply vinegar? Is it mixed in water, and what ratio? Would doubt it's added straight. |
