Are you still going on with this bullshit? You can yield way more with 500W of DIY cobs than 500W of DE. Why do you keep trying to equate the 2 when one is clearly a lot better?
(More light...)
The only reason you do this is because you take personal offense to the fact that another light outperforms your DE setups. That doesn't mean anything is wrong with your DE setups, but your judgement is totally based on emotion, not facts. You resort to lying just to make yourself feel better about your own setup. I understand that you like equality, but your equality view gets in the way of the truth. It is what it is.. Nobody is attacking your grow, so why do you insist on getting so defensive. The reality is that nobody cares about your grow or what lamps you use but you. They just want to know which is brighter and which costs more.
If everyone thought like you did, any form of progress would be shunned.
