I never got around to doing the 3000K -vs- 4000K test so, anyone want some free lamps to do some testing? You would need to be an established member and have documented proof you can keep plants healthy, and be willing to document the grow and give final yield and smoke reports. If you're interested send me a PM.

The offer is for a T22 3000K 90CRI and a T22 4000K 80CRI. Ideally the grow will take place in two identical areas, with same genetics, etc. If interested send me a PM.

I have a couple people who have an interest. I'll give it until tomorrow evening to give everyone a chance and draw a name. For those of you not familiar with the T22 it's my first non-DIY lamp I'm offering for sale. The enclosure is made overseas and I complete the assembly, cobs (Vero 29Cs) being mounted with Arctic-MX4 thermal paste. The heat sinks are to my specifications and keep the cobs just over 10C above ambient. The lamp is a 200w lamp powered by a Meanwell HLG-185H-C700B. This powers the cobs at 45.3 watts each and delivers about 56% efficiency for a total of 101 PAR watts, or about 500 PPF.

Couple pics, the product pic and a pic inside a 3x3 tent.

And here's where it all started several years ago :)

I'm going to go with 3000/90 on this one. It has a small photon count advantage and a better red profile. But maybe there's something to increased levels of blue. We will see.
