I'm still trying to figure goldmines out and have yet to smoke any of it, but that's due to change real soon.
We've got a goldmine, placed in a 65 gallon bag around June 1st with high hopes, which hardly vegged and went into flower real soon looking like it could get chopped any day now. Buds look braided and sticky. Might be 3, maybe 4 ounces on her. I like the early flower of this one, not so enthused about the finish size.
Another one has a different style bud structure and vegged a bit more, ate nitrogen at a prodigious rate (got a little too green) and has some very sticky and large but fluffy / leafy buds developing. This one is maybe a couple weeks away from the chop. Hoping see tightens up in the next couple weeks.
There's a couple more that have begun flowering too, but not as far along yet. They might be 4' - 5' tall, decent but not big enough to get excited about. Neither of those has the leafy sticky bud of the super green one we have going.
I'm real curious to see how others do with goldmine and what some of the phenos look and act like.
