Newbie artificial light questions

[jim the orchid guy]

I have been growing many types of orchids under lights for about10 years. I have a 9x11 room in the basement. I just use the grow lights from canadian tire but make sure they are full or wide spectrun. My lights are on Dec,Jan 12 hr a day Feb March 14 hr a day april may 16 hr a day may to sep 18 hr a day.Then from Sept to dec I drop them to 14 a day. I have 5, 4 tub flurosent lite fixtures when they come on they heat the room to between 75to80 degree them I bring in cool air to cool them down at nite around 60to65 degree.I also have humidity trays to keep the humidity around60 to 70 percent. I also have 4 4" fans that come on with the lites and a 10" fan that blowes 24,7.I can grow cats phal,phap,oncidiums,brassia,epid,etc. The more lite the plant need the closer to the lites they go.The room has only a 2ftx3ft window. The orchids stay in the room all year long. Hope this will help you Jim
