orchid grow lights or no lights

[jap42]

Hello
I know winter is around the corner. My collection of orchids are growing & I want to keep them happy. I have had a catt. since Jan. 2008 & it hasn't bloom since then, she growing. That being said..
I have a ALL WHITE LED Aquarium and Grow Light Panel 225 LED 110 Volt for my orchids...... Do you think that is good enough???? How many hours per day???? Is that strong enough for catts. & others that need more light..

or 2 PLANT GROW LIGHT CFL BULBS 2700K+6500K????
I live in Mo. so some days no sun............
Thanks for all your input.........

I jhave been looking at the red/blue LED grow lights and wishing they weren't so expensive! The sites I have looked at suggest 14 to 16 hours of LED light a day.
As for which to use... Get more orchids, then use both and tell us what worked best for you!

anyone grow with the LED lights?

Regarding your cattleya that hasn't bloomed - usually, when an orchid is mature enough to bloom and it doesn't, then it is not getting enough light. Try increasing the intensity of the light. Do it slowly so as to not burn the orchid leaves. Good luck to you, Joan.

As long as the leaves doesn't get too warm when touched, keep your plants as close to the light as possible. I keep my catts 12" or less (from the highest point of the plant) and the fluorescent lights stays on for 12 hours... Good luck!

i don't think it's possibale to burn the plant with LED since they produce very low temp the same as PL.
