What do u mean?Today I watched few good reviews about the COB's. They're starting to get down 50W to 40 and even 25W after heating.
You get these COB's in 20W, 30W, 50W, 70W, 100W and even 150W but the 150W I only found as cool- or warmwhite.
As Crazy sad - the problem is then u will have heat everywhere and not just on one spot - so it could be a challenge.So I'm a computer engineer and I have a lot of old CPU coolers with fan. Also these COB's are really cheap as you said so I will have a COB setup almost for free
I can't tell u if they will safe u some money - because in real nobody knows how much light these COB's really emitter....or in other words, I dont know anybody with a proper meter to test it.What do you think about the grow room plan?
Using T5 lights for clone is smart choice or should I use 2x50W COB's there too?
Maybe u should use a 400W HPS and then a few COB's to cover all the edges ? This would save some kW/hI'm thinking to switch all the lights to COB's few in few month.
12 COB at Bloom and 10 at Veg are will be enough for this setup without HID's?
I wish I also have a hole room for it
