Weird.. all ~10 of my grow bulbs together probably weren't even 15 bucks... why get such an expensive light? Like, is it even the right color temp?

It says its a blue 6500k on the box. Not sure how well blue lights work. Never used one.
But yeah its excessive, either way.

Ah, yeah, didn't check the box. 6500k is the color temp that's been recommended for mushroom growing for years. You saying you've never used a 6500k bulb D?

No, I use 6500k. I assumed it meant the light shined through blue tint. Now I assume it means blue spectrum. Just dug up this post from RR.
Quote:
RogerRabbit said: LEDs have shortfalls in spectrum, and their performance is not quite ready for prime time. When I built the mushroom farm you linked to in the seedstock article, I used LEDs exclusively. However, it's become apparent over the years that fluorescent lamps around 6500K are the best choice, not LEDs or especially 'blue' LEDs. I've since removed the LEDs from the farm and all 500 feet of LED light rope is currently coiled up on a pile of straw bales in my barn.
It appears you don't understand the difference between blue light and light in the blue spectrum, which actually appears mostly white to our eyes. The latter is what we want, and the weight of finished product grown under proper lighting will be double or more the weight of a grow only illuminated for a few minutes a day or even all day with the wrong spectrum. This is apparent from pictures above from a grow with insufficient lighting. You can see plenty of mushrooms(they'll pin and grow in total darkness) but they're small and the caps are thin. Contrast that to monsters with double or even triple the weight when grown with good full-spectrum lighting.
Lighting requirements of mushrooms. RR

I found the same setup on Amazon and it's nearly 3x as expensive. Is this too much output? I'm reading 6500k is recommended, but this lamp has 4 of those bulbs and the are 4' long each. I've already got it hanging up and used equipment can't be returned. I can still use it for germinating seedlings, if so. Wow this thread went sideways. Lol

Update.
Getting pins on the tray in question. The tray up front was treated with your advice. Second tray looks nice a white. :-) Thanks for the help guys.



Still have 2 back up trays colonizing. I'm waiting for the cakes to finish producing, so other trays are on standby. I'm knocking up 7 qt rye jars today for my second monotub.
