Chironex

Interesting observations Pauly, very useful. I am uncertain which portion of the spectrum causes burning of the leaves, but I have suspected that if this can be filtered out, our plants are less likely to burn. I will be doing some trials under 100% red-infrared spectrum and 100% blue-ultraviolet spectrum. This may be a more empirical study, but should prove useful in TC.

Presently I am using a mixture of spectra as I bought the compact fluorescent bulbs with a high blue-spectrum content on a one-to-one ratio with bulbs of a more red-spectrum. These are used to develop my plants coming out of TC and they seem to work very well. I may convert to entirely blue spectrum as at this stage of plant development, all I am interested in is vegetative growth. They are too small to flower.
