Hi
Looking to start a new experience with a.cob led grow ,probably a bunch of 50w ,probably 6-9
Wanted to ask a couple of questions
are driverless LEDs useless as some people go on ?
Quite confusing as the grows and articles based on research show otherwise
Also is this due to the efficiency e.g run to hard therefore running way hot.?
If not then why?
Which cob LEDs should I get ?
Are epistars a good bet ?
Also would 4 full spectrum.2 cool white and 3 warm.white be a good set up ?
I've seen millions on eBay so can't really distinguish but some direction would be great
And if standard driver LEDs are the way to go then how efficient can they be if running them adequately soft ?
I ask this as some.of the driverless LEDs I have been assured are about 50% ,e.g 50w cob =25w actual light lumens
Hoping to have a decent discussion about this
Also if standard cobs with a driver are the way to go can someone please help me sourcing some of these ,the ones on AliExpress and eBay are like 90lpw ,what's the point , live in the UK btw
Thank you
