Interesting because if MH has a "negligible" amount than that would mean that sunlight also has a "negligible" amount of UVs...

(using your 5w out of 1000w as a base)

Realistically if youre going to claim the "need" for supplemental UV you must also proclaim the "need" for CO2 levels to be ~1500ppm.

Comparing 5W of UV (A and B combined) to the sun is odd. You do NOT need 1500PPM of CO2 till youre at 86F and pushing past 1500PPFD in lighting ( and trust me not many people are). After that its needed, till then its all based off of having the normal amount of CO2 and that temperature for max output... Of course it does help in a sealed room because that way you maximize the CO2 usage...But its only so you dont have to use a carbon filter really.

Thems the numbers, you just dont get a good use of the CO2 without the higher heat and light output. Which you wont be getting from a gavida unless you have alot of them running close.

I have the graph that shows this in my signature.

How in hell are you cooling a 5400 watt room using just fans? Summer months? Wtf???

Yes easy I have 4 large fan all together about 5300cfm and draw the cool air from under the house. Not mush I can do on very hot days I just turn the digital ballasts down but that are days over 40. Most of the time over summer the room wont go over 32. Over here where I live no one uses ac they all use large fans to cool the room and it work fine

Wish i could get away with a 5000 or 6000 watt room without air conditioning. Here in the Mindwest U.s.a. there is just no way around it except the middle of winter.

Nice charts man. That SE hps looks like one of the best options there at 2 foot, being some are dropping lower then that.

Ill stick with the cobs all day, but the side by side will be the determining factor after I get them tested. Should be the end all when it comes to yield/TCH/quality/CBD/GtoW ratio and everything else.

Have you ever had bud tested?
Click to expand...
No but I was out of product my first run before I could test! Which is a good thing lol. So I would guess it was mid at best like around 20% or so nothing crazy. I will have everything tested in Ann Arbor or through a connection that owns a dispensary. But I did have the test results from one plant in my garden when I got the clones that was 28% which I would be happy with.

It was tested from the plant that the cut was taken from so should be close.

I think likely we'll see them be distributed more to major big box outlets and the price come down substantially. Gavitas for ~$250 at home depot...that sorta thing. Generally when a small niche company gets taken over by a bigger broader company the quality doesn't improve but the distribution base gets wider and price comes down. Who knows though it would be nice if they continued advancing their tech in the process. Another problem I see with cobs is all the builders and users are most interested in chasing new tech than improving price points on existing modules. I believe the Cree that came out before the 3590 (CXB 3070?) or Vero 29 can be put together quite cheap and would still work great but everyone wants the new latest and greatest. Now everyone is about to move on from the 3590s and start chasing the Citizen 1825s. Give it a year and 3590s will be dirt cheap but nobody will want them and few will be building them.

on the contrary I'll be building them, sorry but you are missed informed . the 3590 is almost 40% more efficient than the old chips. and when you invest in a bunch you do pay short money for the chips. and best of all all you need to do is pop out the old chip and pop in the new chip . two minutes and done with the new technology. led is the best lighting period when it everything so why wouldn't they be the best to grow with .simple logic. gravita DE Is already old technology. thanks for listening
