    Most likely you would need an HID system, but you have to be careful with them due to heat. They are also expensive to buy and run.

    I researched this last year and was very confused with all that was offered and all that was said about the different systems and the expense of some of them. I finally decided to go with shop lights and did a mix of fluerescent gro lights and high sun. I have had great results with my 100 plus orchids. I grow catts, paphs, oncidiums, dendroiums, phals and some species. They have all thrived and bloomed and the cost is very affordable. I have two double bulb fixtures over my tables. The fixtures and bulbs cost me less than $100. I bought them at a big box store. A friend who is an electrician installed ceiling receptacles for me and a timer. My electric bill went up very little and as i said the results have been a success. i would suggest you try this method before sinking big bucks into more elaborate systems. Your main expense would be, most likely, having a timer and additional receptacles installed. Good Luck! Bill
    I posted pics of my grow area under a thread entitled my attempt at a gro area. Take a look. Perhaps that will help you.

    My orchids winter in my basement with no natural light. This past winter, I put two 4 foot long high output T8 fixtures (a total of 4 bulbs) over the shelf of high light catts and vandas. Some of the catts have bloomed under these bulbs. The vandas haven't, but some leaves of the oncidiums on the shelf beside the high light shelf have turned purpleish. The shelf below has a three bulb high output T8 fixture. One of the young catts has bloomed under this fixture.

    wow really, so do those T8 fixtures give you enough light to bloom your catts, dont they need a lot of light?? I already have my orchids under 4 T8's but i dont know if thats enough light. i'm planning on buying a light meter but i dont know which one to get. i already got a thermometer/hygrometer. the plants seem to be doing ok under this light and most of them have new growth and root growth but i wanna be sure though.

    I have HO T5 fixtures (4-bulb, 4 ft) and have a couple of catts/laelias and they are doing fantastic. I go by the response of my plants to their conditions rather than using instruments, because often times the plants don't read the books . But everyone has their own style of growing that works for them.

    You can pretty much bloom anything under T5's and your electric bill won't suffer as much as with HID's.
