If you go back and read my original post, I stated that they are "imo, a vastly superior supplemental light source"
If you read any number of build threads featuring kessils, they also use t5 80% of the time.
They are also pictures of frags, not colonies.
As stated, the evidence is in abundance for the black boxes, even in this one thread.
You use halide and t5, a tried and true method that can't be disputed, yet you argue for the kessils because of your lfs?
I insulted no one, just asked to be proved wrong, and yet again I wasn't. Then the bandwagoneers feelings were hurt and I'm the bad guy.
Your argument has been completely invalid from the get go, since you use neither light source. Thanks for your opinions, but let's stay relevant.
Again, IMO, both lights work to an extent. Kessils have the control, features, and sleek look.
Black boxes have the power to turn sand into glass, but lack the ability to control.
Ultimately we are both right, it's the OPs call fashion or function.
