Peyote Critical - UK outdoor

Last year I stuck some plants in the ground too early and we had a 2 week long frost late in May. I wrapped them up but the only one to really survive and flourish was a Peyote Critical. When I harvested her, instead of the roots spreading out like normal there was a 24" tap root running 2" under the grass straight toward a black compost bin and forking toward another compost bin in picture 2. I got 8oz off it and it was a beautiful smoke, uplifitng and strong without couchlock. Pictures 4 + 5 are from just before cropping last October. So this year I moved the compost bin and stuck another Peyote Critical in it's place. She's 14 weeks old and gonna be a beast, if the weather is ok. I mixed in some bonemeal, mycorrhizal and guana when I planted her and occasionally chuck a bit of magnesium her way but the rest is down to nature.
