How much harder to grow is PE compared with (say) GT or AA+?
And is the buzz really worth it, compared with those two specifically?
Part of my problem is my house is incredibly dirty. Its a duplex and there isn't much I can do with the overall condition of the property. I think if you had ultra pure air and time penis envy would outperform all other cubensis on a pure weight basis. Me personally I don't see massive differences in mental high of any of the cubensis.
I think the problems I've had with fruiting MAY be bacterial contamination. That's just my theory though as I don't own a microscope. It could be that penis envy is just a moody bitch.
About half my PE bins made it to fruiting. I've also been growing GT at the same time as all this. You can see my thread. GT is at the top of my list currently of real easy to grow kick ass strains. I haven't grow the other one you mentioned.
I'll probably grow PE again but only when I have more room to experiment. Its hard not to be impressed with those giant fruits that you do get. I've heard of other cubensis getting giant fruits but I can't tell what the formulae is to get that result.
