Ttystikk's vertical goodness

What are your CO2 levels? Max light +max nutrients needs max CO2 to push your plant to the max. Also, I wonder about the necessity of using lens on COBs used in SCROG. I would think a better spread would even the lighting and the plants would be cooler from not dealing with focused beams of light.
Or it is possible, you just have more light than they need! Imagine that!

Ok so I got a head scratcher for y'all; last run, one of my modules wasn't working and so the plant only had three modules on it rather than four.

That's the new record yielder. Haven't weighed it yet but it looks bigger than two.

Go figure? I honestly think I'm dealing with the plant's inability to handle all the light I'm giving them. It could be my fault, as the final pre bloom veg ran just 1/6 the PAR W/sq ft of the COB rack. I've since bumped the watts of lighting in the prebloom zone up by 85%, hoping to handle this problem before it happens.

Above, I discussed that I ran half the modules for several days, added the third for several more days and turned up the fourth and last only after a full week in bloom on the trellis. Now at day 15, they aren't laying down 'as much' as my last two batches.

Maybe more nutes? I'm easing my EC upward to see what happens. They've been eating a hundred gallon batch down from EC 2.1 to 1.6 in less than a week. So this time their fresh batch is EC 2.3, we'll see what happens.

Plenty of CO2, and don't make the same logical mistake everyone else is. If it was too much light, the very same modules would be burning the plants in my veg area.

I can't wait to see the big reveal on your cob panels and am interested in yield reports etc. But honestly I just don't see how putting that many watts of cob at each trellis is making any improvement over hid.
I mean, if a bare 1000watter can service 4 trellises that's only 250W per trellis.
Can cob produce at 250w per 4x6 trellis?

I did a straight watt for watt swap from HID to COB LED. The point of the exercise was to see what the difference is.

So far I'm getting better light and twice of it. What slays me is all the knuckleheads telling me something is wrong with my lights, when clearly I'm only having problems because they're working so much BETTER. After all, my girls don't shock when they go into HID.

As far as improvements go, there's a noticeable improvement in quality and yield, even while I'm still screwing things up lol

can you adjust the mark/space (pulse width) ratio of your cob's ? less on time would lessen any shock affect without losing any lighting effect

They're just continuously on.

Again, the problem lies with the veg. Not enough light in there leads to light shock when they hit the big time.

Weren't you lighting more than 1 trellis with each 860CDM?

One 860W CDM Allstart lamp ACTUALLY pulls 1080W from the wall, because the mag ballast drives it at a thousand watts and needs the other 80 for itself. 5 of them = 5400W.

24 modules at 225W apiece = 5400W.

Your evading the question :P
You were only using 1 side of the CDM lamps pointing at a trellis or where there trellises around the lamp?
I assume with the cobs you are blasting more watts straight at the trellis?

I arranged the half dozen trellis panels vertically, in a racetrack shape. The lamps hang vertically and bare inside, their omnidirectional light shining on the interior where the plants are trained.

For the COB modules, the panels are flat in two facing rows of three. The modules are in the middle, shining to each side.

Same six trellis panels for the same area, same watts- just different light emitting devices.

Like having to harden an indoor plant to the sun or it stunts them.

Plants don't adjust well to abrupt changes in light.

Grow one under a single cfl and then throw it under t5. It will do the same.

I go from T-5 to 1000 watt SE and DE, never had a problem. Also go from aquarium floro with clones to 8 bulb T-5's, never an issue. I believe its something else. Basically whats been said is a 2-3 month old vegging plant is getting problems on light change. I could be wrong, I'm only trying to help. The OP doesn't like me, but this is one of the best journals going so i watch it.

You may not have problems.

Doesn't mean that its not true. I've seen with my own eyes.

Don't kid yourself; you're nowhere near a significant enough figure in my life for me to waste energy actually hating you.

I just wish you had a better attitude.

All else aside, thank you for the compliment.
