Current top bin LED's beat HPS easily by around 20% and more. An example, Osram Square series diodes in deepred reach up to 3,9μMol/J(watt), a 315w CMH is 2,1μMol/J, a DE HPS has ~1,9 and standard HPS have even lower efficiency. Current Quantumboard v2 has for instance ~2,5μMol/J efficiency and 4 of them with an HLG-480 driver(500-550w max.) are used to replace 1000w HPS with no loss in final yield.So do people generally find it's better to HPS for budding and keep the LEDs for veg. I hear the people saying they are strictly led but can anyone thats tried and used both answer ?
There are lots of vids on youtube(GML show, ...), mate, and here are a lot of qboard related threads.
I would suggest you look at a few...
