Light ???

It is. If you look at my light in my cab I cut four big flaps in the reflector to let heat go through. I didn't need it after exhausting outside.

You will see a big difference even with the other lights when you exhaust outside. You will most likely not need the portable a/c.
Trust me the A/C is needed. I bought it because it's cheaper to run this in the grow room which is a spare bedroom than to be running the entire house at a certain temp to keep one room cooler......so I have no regrets on the portable A/C that was coming regardless........

We will see. I think you will be surprised at how much difference exhausting outside does.

Ironically the ones that hate it the most are land races
Do you think after so many years of people breeding that maybe some of the strains have evolved so to say to prefer indoor type lights? And maybe this is why these strains do not like the UV because that starts to mimmick more the outdoor world? Just thinking out loud here.......

Yes. They acclimate to where they are growing. It is why some strains breeders reccomend only indoors.

One not ridding the heat from the house and two not hardening the plants to the UV.
I think I'm okay on the first in terms of excess cooling capacity, although it always needs to be accounted for.

On the second, that's good advice. My plants will not have seen UV and will therefore need a transition. I think that a few 15 minute on cycles for the first few days, then adding more for longer as the cycle progresses makes sense on many levels.

I suspect that strains that come from higher elevations will do better.

I suspect that breeding with that light on will also help as strains acclimate over a few generations.
Nah, it's just that the plants themselves need time to acclimate. Some plants are growing more vigorously than others and can adjust more quickly. Certainly strain plays a role but I doubt there are strains that simply can't handle it.

In another part of the same veg space, I have two COB LED modules; each runs 4 CXB3590 3500k CD BIN at 54W each, for 225W. That 450W mops the floor with the 550W of the Mars Hydro LED in veg mode. It's not even close. Everyone who looks at them side by side- because they are- agrees.

It's just fun to play with the unit.
How can someone say it blows it away when they both would grow pretty much the same , IMO would like to see pretty sure daily difference is unnoticeable,, weekly ?? may be one stretched more then the other ?? ..
You got any pictures of actual plants?? and lateral branching difference ? just because it looks bigger does not mean its better ..
what you need to do is test this grow 2 plants exact strain 2 weeks from clone compare height, lateral branching, how many bud sites , and most importantly root size as in growth ,, One may grow better in a certain stage yet when it comes to bloom the smaller one or the least likely out performed the bigger one , I seen it numerous times

You wanna do that, by all means get yourself the rig and the gear and test it. I've already made and shared my own judgement, take it or leave it.

The more salient question to ask would be, "WHY do you think so?"

My answer would be that the Mars panel suffers from;
1. Less efficient chips
2. Poor light distribution
3. No lenses
4. Relatively inefficient spectrum output
5. Plants apparently need different nutes than under other lights

Better is better. In this case, a lot better! This unit has proven to me that my investment in COB LED lighting was indeed money well spent.

That wasn't directed to you. I don't think.

I'd say all of them can acclimate to it.

I just meant that strains that are from higher elevations have been exposed to higher amounts of UV for generations.

Its supposedly why places like the Hindu mountains have good weed.

Now, my COB LED chips make no UV so it makes sense to supplement with it. I'll start with 2 x 4' Agromax (is this the highest UVB lamp?) per trellis. I'll let the plants tell me if that's enough to make a difference.

It is pretty much common knowledge here that blurple lights are inferior to cob and even t5.

This site doesn't sensor its members. The reviews of products, even from advertisers, are honest.

Other grow sites will ban you if you speak badly of their sponsors products.

It is also known that on other sites where members are growing huge plants with them are being a little misleading. They run double or triple the panels. Then someone goes and buys one and wonders what's going on.

It is also very well known that the makers if blurple lights are dishonest in their marketing claims. They claim outrageous numbers and claim a 3-400 watt panel can replace x amount of hid watts.

Then you have companies like advance on amazon ripping off a legit company.

From what I've read the agromax pure UV is the best UV light. They claim more UV than reptile bulbs.

I know you have to shut them off or cover up when working around them.

For this reason I plan to have them on a separate circuit so they can be timed and shut off as needed.

Of course the mars hydro LED gets destroyed by top bin CXB. Are you kidding me? We're talking about the difference between 20-30% efficiency and 50-60% efficiency, and you really expect them to perform equally?
