COBs are too pricey and difficult to handle (multiple tiny lights bolted together).
It's so much easier to just buy a single fixture that works well.

Yeah maybe in a few years. At the moment COBs are just too DIY oriented and the pre-built fixtures are a lot more expensive than CDMs.

- Prebuilt fixtures are pricey only because of the components.
- Better efficiency means less cooling. A LOT less cooling than DE.
- Better spectrum means better buds.
- No lamp replacement, means no slowly degrading lamp invisibly costing even more efficiency.

I'd use the same fans with COBs as I do with 315w CDMs.Any questions?

I think CDMs have a pretty good spectrum already, and they keep their efficiency better than standard HPS.
I can't afford COBs, but I can afford CDMs.

They're a transitional step. I did the same.

I still can't get anyone to build me one like @legallyflying. I just need a six footer.

Yeah light penetration / light intensity would be a good question. LEDS always lacked that. You can't beat dual 600w fixtures w/ MH n HPS DE's and 860w allstart CDM bulb powered by a 1k badass ballast on a parabolic. All on 240v.

I bet we know the same people; I'm running an 860W CDM Allstart lamp on a badass, too- only I'm doing it in veg.Yeah light penetration / light intensity would be a good question.

I promise the COB LED rack is pushing out way more light than your motley crew of dim bulbs! Lol j/k! You should see it, seriously.
Sounds like alot of A/C would be needed for that unless it's a huge roomYeah light penetration / light intensity would be a good question. LEDS always lacked that.

Well mostly freebies since first grow indoor in 20 yrs 9 autos, 4 are unknown as is the one in bloom they were Buddha auto fem. other 4 autos are a afghan kush freebie, free dark purple, free amnesia, and Twins Alpujarrena these were on sale one Pineapple Express auto one week had hull issues. The 4 photos are free afghan valley girls. Plan on putting them outside in two three more weeks, alone with the smallest autos.
Soil is ffof with perlite, vermiculite, teaspoon blood meal, bone meal per gal. Added 5 6 grains of 33% nitrogen on outer edge of bags. Root bags 5 gal and 3gal
Using half dose cal mag each water no nitrogen due to blood meal and 33%. Half autos I did not it add the 33%. Just test.
Afghans photo use same soil mix.
Plant in flower same soil added jacks half dose of 10-30-20 first week l flower added small tablespoon of age old dry fruit this week 2-26-20. Not right close lol. Water with ca mag other as well with autos. Plan on same does ever other week last two weeks age old only.
This is close. Just got to decide who goes out and who stays.

550w of LED has more penetrating power than a 1k gavita hps, the efficiency and lack of heat definitely beats HPS.
