Hrothgar

@Puffer_Bill, thanks mate ;)

@Hrothgar, i grew 4 plants under 315w Amare SE300 in 1m² (looks a bit like your setup), the cheese gave between 60 and 100g, its not dry yet so I cant tell. Very fast growing big spearhead colas.

@Puffer_Bill, @@Spaceman said it all. Currently using 250W Phillips HPS Gro+FLO at 40 cm away from leaves. Thanks for the positive vibes. Update Coming soon.

@@Spaceman, thanks bro, what do you have to say about the yield amount ?

@James, Thanks ;)
