Prismatic is a modular, wifi programmable, multi-channel LED light that gives you precise control over the the spectrum you give your plants. Connect with your phone or computer, the web-based scheduling system lets you create simple and advanced programs.

I built Prismatic to optimize light spectrum for organogenesis and regeneration in tissue culture, but it can be used for any precision lighting, photobiology, specialty plant growth, or plant propagation situation.

• intuitive wifi-programmable UI for programming advanced schedules
• upload programs, replicate experiments

Each Prismatic module can be independently programmed, try growing your plants under different conditions and see how they respond. Perform controlled experiments using the Central Composite Rotatable Design. Generate a response surface and find the optimum mixture of spectra. I then validate this using replicated studies.
