Hi all, I'm an old school farmer back in action now that my kids have moved out of the homestead. I always used HID lighting but figured I would try LED's with my training wheels grow. It's been over 10 years so I ordered some old favorites ( I like the classics ) but am just using the free beans for this test LED run.
I ended up going with 2 600W Maxbloom CREE 6X lamps and a 5 X 5 Gorilla Tent. I only have 1 600 up now as I'm only 3 weeks into vegging my seedlings. 2 X Blueberry, 1 X White Widow, 1 Amnesia Haze and a Neville's Haze. The Neville's Haze looks like a runt but the other 4 look great, just as good as when I used Metal Halides. Actually I would say better as they have the shortest inter-nodal lengths I've ever seen. They are also showing nice thick tree trunks for stems. Oh, I'm growing in Coco for the first time. I usually use Ebb Flow or DWC. Just wanted to try it out. Also using Advanced Nutes Coco formula.

I currently have 1 lamp about 24" above the plants. Seems like they are not needy at all as I see zero stretch. The veg dimmer is all the way up. When do I introduce the bloom spectrum? When I go to flower? Or do some folks use a bit of bloom dimmer and if so why?

Thanks - Ned
 
In my country we have an old saying: If a device has a turbo button, use it ;)

Once you're beyond the seedling stage and in proper veg, crank it up to max - more light equals faster growth.

I think these grow/bloom spectrum switches/dials are BS, use full spectrum all the time, and full power for maximum PPFD on the plants.

I really like your take on lights. You seem to know a good bit about them. "full spectrum all the time", "dials are BS". Give a man a knob he will turn it!

This has been our philosophy and science/design all along. No knobs, full spectrum all the time. Just like the sun!

Hi all, man they look so good on just the veg dimmer I haven't tried to introduce the bloom yet. My seedlings are about 3 weeks old and they are looking great. Very very short internodal lengths, super short and bushy. Nice fat stems getting woody. I intend to veg them another 3 weeks then flower. Great point about the sun though, I guess it has no dimmers LOL.
 
My philosophy is full power on all channels. If the plants don't like it, back off the power if it's adjustable, or raise the light if it's not.
