Quarantine grow of OG Kush and Gorilla Setup : 3.3'x3.3' grow tent 4'' Fan and carbon filter 300W of VERO29 DIY COB LED SCROG Net Nutes Greenleaf Megacrop Greenleaf CalMag Greenleaf Bud Explosion Mykos extreme bennies Had a rough start, my cheap PH pen broke the day I made my reservoir which resulted in my seedling being in 5.0 PH solution. Getting a new pen was pretty slow because of COVID19. The poor babies mutates and looked like shit. After 5 days of being in the corrected reservoir they look much better but are pretty beat up. The sativa phenos of OG Kush are looking pretty bad.

I've noticed that LED manufacturers are tending to change over to the new COB LEDs .What are the advantages of these new lights over the old standard LED grow lights? if any?
