Here’s mine: 9 x 12 indoor climate controlled. Lights are ALT LED 5,000 K (natural sunlight), high intensity, 60 degree T5 tubes (4ft). Each tube draws 50 watts energy. I use 1 tube for Paphs; 2 for regular cattleyas and 3 for high light catts. (Fixtures hold 1-3 tubes). Lights hang on carabiner cords from 8’ ceiling so can be adjusted to any height to achieve correct PAR. Lights on all catts are +- 24” above leaf canopy. For Paphs a little more. This produces the PAR they all need. Lights only raise temp of room about 5 degrees. They are all together on a timed switch that runs them from 11.5 to 13.5 hrs. per day depending on the month of the year. I love the headroom my lights give me as room would be claustrophobic with them close to plants. Fixtures can be made to hold 1-6 lights. You choose. (Orchids Ltd.)
Temps range from Hi-84/Lo-70 in summer to Hi-72/Lo-62 in winter. No windows in room (in basement), so I open and close the door from day/night and use fans/heater to control temps. Humidifier keeps it at 50-55 humidity summer and 55-60 winter.
I water in the sink with a 1/2 HP pump pulling my fertilized R/O water from a 10 gal trash can through a curly hose with small wand. I use an app (Errands) and color coded tag to know what plants to water each day (rather than every 7 days, etc. for all). Table #4 RED for instance.
I grow on 4’ x 30” tables that each hold 2 plastic boot trays perfectly, in clear plastic pots in Orchiata/ charcoal/perlite mix sized to pot size. I also grow about 10 Phrags and 4 phals upstairs in my bathroom East/SouthEast large bay windows at ambient room temp in mostly bark mix, but some are in rockwool/leca mix. The Phrags did not like the 84 degree temps of grow room.
I have about 89 plants. 75 in grow room and 14 upstairs.
Cattleyas are large, many in 10” pots, so trays are quite crowded right now awaiting division and gifting. When they bloom I move them up to our living area window to enjoy them.
