Lighting Questions

Perhaps there was an overabundance of certain toxic gases in the atmosphere at the time Paphs were evolving their stomata controls. High concentrations of toxic atmospheric gases at certain times could have blocked blue rays from reaching the plants thus preventing them from opening their stomata. This could have been how Paphs protected themselves from high levels of toxic gases. Don't get me started... :rollhappy: I love to conjecture about stuff like this. :wink:

Well some of them are near active or extinct volcanoes right?

Indeed!

I still have lights on the brain. Found this, which some people might be interested in: CFL, high lumen, right colour temp and very easy setup. There is also an 80W version, but it's a GES connection rather than standard ES. Might be good for small setups and/or flexible supplementary lighting?

Yeah, a 40 watt actual wattage (~200W incandescent equivalent) in a simple clamp-on fixture will give enough light for a square foot or two- great for a small garden of lower light plants (phals, Maudiae hybrids, new world zygopetalinae, etc).
