I veg with my cxa3070 3000k when needed. The stretch can be managed with shear intensity. Works great

Crazy, you guys joined a day apart! Welcome aboard!

The lower the temp the higher the lumens. I would add a couple fans and sleep well knowing that if they ever fail it won't be a problem.

She should be able to adjust to it but it might take her some time. Can you dim your driver?

I never worry much about the bottom leaves. It does look like she is responding well to the 1/4 strength nutes. Have you looked into "mainlining" as a training method? Four main colas would fill your space very well. I also grow micro in a 20"x11"x29" space. I have found it is just enough space...

Check out tasty led. They have a three cob lamp using top notch components.

If you have a little electrical knowledge you could add diy cob leds in a little at a time. Maybe start with some 3 cob bars on each side and drop the 600w then add a couple more bars and drop the 1000w and add back the 600w. You'll know when you hit the sweet spot for the plants and the power bill

The light sphere that catches the photons is not the reflector you guys are describing. To replicate the light sphere you need to change the surface that is catching the light (the plants) and train them stadium style to reach up around the edges and grab the light that would be hitting the...

Are you talking about red party bulbs?

Sounds like a good plan. If you end up upgrading later you will have wasted every dime spent on it though. Why not buy a little vero at a time until you hit your end goal?

You could also leave them at 6-8" and dim them a little. I'm running at 4-6" and 42w, although I'm getting a little bleaching too.

You might have better luck asking sunlight supply for info about their HID products than asking us.

Will the 730nm induce stretching if left on?

Could be bad wire as well. If the wire was stretched at anytime it could have broke inside the casing. Time for a continuity check.

Those are different reds (730nm far red) for lights out. If you run them all day it has been said to induce stretch.

I understand it uses that light more efficiently but I still don't get why you call any light outside the curve a loss. Does the plant reject that light or adapt to its environment and use it?

I am having a hard time understanding what you mean by losses to the McCree Curve. Does the plant disregard these photons or just use them anyways?

Just use it as it is. The plant will be ably to use the light even if it's not the perfect spectrum for flowering. I have seen great flowering results posted by growers using mh the whole way and they were frosty as hell. If it's bright enough to grow coral its probably bright enough to make...

Would the spectrum chart found on the data sheet showing relative power be fairly accurate if comparing 80cri and 90cri if they were the same bin?

I didn't imply anything about the 80cri. I think mixing both cri variations of 3000k might be my next route. I was just saying the McCree Curve isn't a hard rule. It is what the plant is most efficient at using but the plants don't disregard extra light when it doesn't match the curve exactly...
