Or perhaps he's got small children or animals that can get into it. Compressed CO2 systems are not without their dangers, nor is DIY CO2. This hobby got to where it is now because people chose...

The absoluteness of the assertion that the actinic component does "nothing" for plants is its own downfall. Most actinic blue lamps feature a spectrum with a pronounced spike at about 420nm, which...

I didn't mean to suggest you were referring to overstocking. Overstocking represents a gradient, anyway, not a specific point. As you said, less is best. But the problem is that people have bought...

Chlorophyll a's absorption spectrum peaks strongly right at (or very near) 430nm. While better lighting options exist, to say that the actinic light isn't doing anything of benefit is a bit of an...
