Spliff is right some of the hardest buds I've ever grown were fast buds gorilla glue. THey were very large, skunky AF and hard as a rock. I don't know why people bash FB, I've never had nothing but great buds from them. I've grown Mephisto, a lot of night Owl, Ethos, Rocbud Inc, Gas reaper and they're all producers of hard nugs. Depending on the grow room temp. I have a cooling issue and my grows in the summer arent as hard as my fall/winter grows. I just can't afford to keep that grow room cool running 3 X3-500, 0-500 true watts. I think the BTU's are over 2200 each so thats 4600 btu when plants are budding and the lights are cranked to 100%..I keep it under 89 and a few fans but I can still tell a difference between summer and winter grows...If you haven't grown Banana Daddy from Ethos you are missing out. Its by far my most popular strain. People are begging for it all the time..It too has great bud structure and the high is phenomenal ..It energizes you and is very euphoric and if you're shy, youi won't be for long. It gives everyone the urge to talk a lot...People love it...OH I forgot I have a California lightworks solar 500 in my 3x3 where I will usually grow autos but use it for photos when the urge hits
