Fanleaf's Huge 42 COB Array Build Plus Other Builds

Half , these were flowered under veros and 600 watt hps. I have 9 vegging that's going under the 24 veros tomorrow. I gotta transplant into bigger pots and let veg couple more weeks. Thinking about shutting down the 3x3 till fall, I got way too much smoke, I still have 75% of last grow. Everything is personal, I can get rid of it quick when I start blasting lol. Need to order some citi chips, fan sent me program for citi, need to open it up and play with it.
Well you did a great job. I always end up with more too. Even giving it away to fellow patients doesn't make the pile smaller with a new pile always brewing in the tent. I still have some Dr. Grinspoon from last summer. Can't even smoke that insanity train.
 
UVB/UVA Question:

I can add an AgroMax pure UV T5 4' to my current grow as soon as the fixture comes into the shop I ordered it through, hopefully tomorrow. I already have the lamp.

In your experience what is the best schedule to use this light?

I saw where FanLeaf roasted his face (ouch) with one of these and will heed that lesson.

The Green Cracks are really stretching now but I figure I have at least 4 weeks or more to go.
 
I had a cow solar storm with uvb bulb. They only recommended 2 hrs a day from around 4th week of flower till end.

I'd say way less than that. Put the light up high and maybe 15 minutes a day tops. That stuff will quickly fry your plants. I only use mine for after the Grow. I put it in the tent during dry to ward off fungus and spores.
 
And yes. Yes u can.
Running the SE at 1400ma will give you 50w per cob. I always use/recommend the 1 cob per square foot rule. I run my chips at 1400ma dimmed down 40% and 24" away for veg and at about 20% dimmed at 12-16" for bloom. Max power and cold temps for the last 3 weeks.

Hey Jimmy... would you use 4000k on all 32 cobs or mix it up?

I would go half 4000k half 1750k. Or maybe 3/4 4000k and 1/4 1750.
The 1750k gets you that 650-700nm wavelength you can't get from most chips.

It extends right into the 750nm and infrared area.
 
Clw, damn spell check, I type then send, I need to start checking before lol. You'll have to play with the uvb, like jimmy said start high. The clw uses 17 inch bulb not 48 inch, 2 hrs didn't hurt any. I have 4 of the agromax pure uv also, going to use 3 of them for next grow.

I want a cow solar storm. Sounds amazing.
