Was at the store yesterday, and saw a 4ft flourescent bulb made by philips, labeled for plant aquaria use. Out of curiosity, I looked up the K rating at it was only 2600. The box said the wavelengths were 'tuned' to promote plant growth/absorbtion.
Why do we/you(Aq. Adv members) recommend bulbs as close to 10,000K. Do the philips engineers know what they're doing or not, and has anybody tried this bulb firsthand?
