I love Yumbolt.
Hands down one of the most underrated cultivars out there.
I was lucky enough to get some before he crossed it to Skunk, which he told me him self at a trade show.
My last few pre 2000 seeds were all female so I had to cross it to my only male at the time which was a Shit from Mr nice.
I'll get round to them next year as I really do like this strain.
It's shame to see Tony's web site these days, it looks very dated & very little info on all the fem offerings. Not really interested in fems mind but at least he's honest about not making them himself. I wish he would get back to making regs.
