Yes I have heard of these and yes I have grown it myself.

I can say it was an interesting grow. It did indeed take about 8 weeks from seed to harvest. What is nice about this stuff though is that it is an autoflowering strain, so it even flowered under 24hrs of light, that's why it doesn't take long. After about 3 weeks in veg it starts flowering on its own.

The potency was okay. I'd say a 7 out of 10. It can be high producer if using the right lighting and conditions, and person can easily produce a gram per Watt. I'd say buy them. Only for a resonable price though. I would pay no more than $50 for 10 seeds. It is not worth anymore money than that, but it is fun, and so easy to grow, and stays small. Good luck.
