I have had 4 flushes from some blocks recently using pasteurized straw only (5 lb blocks). It's cold ( 55-65 Deg F ) in my tent, being that I get fresh Winter air from a vent pipe going into the garage which has very low CO2 and blue oysters like it a bit on the cold side. My opinion has been that this strain are very strong growers. Very satisfied!

Really happy with how this performs! Great growth on day 2! 5 stars!
