Light ???

To answer with my limited experience with indoor light spectrum. I started in my new flower room last year with 1 Hortilux 400w Blue Metal Halide and 1 Hortilux 600w Super HPS.

It looked beautiful in there. And it even darkened my uv sensitive glasses. However even when I put the 400w Super HPS in place of the blue (it seemed to lose light much faster than my other bulbs) the plants responded to the higher lumens immediately.

Now I know plants don't use lumens except for PAR but you could see the accelerated growth and vigor. Also the runs last summer started to grow bigger and more potent to smoke.

Now with 2 600's the yeild and potency is much higher. And more consistent. I believe that to be because of good penetration.

Also most things I read say you can only get better results with the right mix of red and blue and the wattage of the blue has to be equal. I think 2 to 1 red to blue is recommended by the universities. I am sorry I did not check my facts before posting.

I am going to say lumens are a real good way to tell if you will have enough light with any agricultural lighting.

They sure did look better to my eyes with that sunlight bulb in there. I want to put a 400 MH in between the 600 HPS hoods.

When I ran round vertical silos, I put 860W CDM Allstart lamps in them. I got up to three in one, 96 sq ft. Did good, too.

COB LED is way better.

I'm sorry to hear that? The kitty liter I use is simply Calcined Clay, no scent, no odor control, it helps aeration, it retains water and it slowly adds sulfur or IOW creates a sulfur rich environment
Using calcined clay is one of the best tips I've gotten here on RIU. I even put 100 lbs in my garden & it's kicking some serious butt.
WAY better than perlite.
Thanks RM3!!!

Quick question: I normally run UV all the way through flower. (4 lizard lights in corners of tent)
Would it be better to turn off UV for the last week? I'm halfway thru week 7...
