Howdy, was a member years ago of The Garden's Cure, if anyone remembers that old forum site.... Anyways here now and thought I would post up a grow. Barney's Farm-Runtz Muffins at 4 and 2 weeks flower respectively.
I grew out 5 Runtz Muffins not too long ago. Watch for herms. Some male flowers here and there. Slower growing and leafy with fairly dense nugs. Not great tasting or resin monsters any of them. Fairly uniform. Kinda blah. Left me disappointed. My last straw with Barneys.
I did pluck some balls off the lowers of the Runtz x Layer Cake now that you mention it. Maybe about 5-10. Never came back. It was the only plant I had going at the time in a 2x2 so I let it ride. Glad I did though, turned out nice.
