Just water
I had a little smoke of the ones I did under the sf1000 ( in flower in 5l DWC ) it’s devastating, really devastating, sit down for a bit , headrush , lifting heavy weights may result in dizzy spells ( trust me )
Very curious to how you'll end up liking your lights. I was in the fence about which new panel to get and ended up going with qb288 v2 r. I like how the spider leds are coated. I've subbed up for this run. LM301B are pretty much the best diodes on the market.
