Hello!
I got this 20W grow bar recently but I am not sure whether it would be sufficient to grow my orchids. I am attaching the spec sheet along. Please let me know if it can be used and if yes, at what height should it be from say Phals, Dendrobiums, Oncidiums and Cattleyas.
Would greatly appreciate your help!
P.S. Also let me know a good place to start reading to understand lights and spectrums and all the scientific terms.
