You can build horticultural lights with our drag-and-drop Configurator, in addition to aquatic plant and reef lighting...we build quite a few custom spectrums for horticultural purposes. The only thing you cannot currently do within the Configurator is select XB Series rather than Original Series, so if you want the higher-output XB LEDs you'll need to send me your custom spectrum report and I can enter the order manually. Did this answer your question? If not, let me know!
ps--If you're in the Austin area this weekend, stop by the Heart of Texas Orchid Society's annual show at Zilker Botanical Gardens...I'll be there and have some of the orchid spectrums on display!
