So far the Green Crack is the only one.

As far as yield and easy to grow the GDP is excellent. Ny Sour Diesel is another excellent yielder and great smoke.

My favorite smoke is the OG kypronite....not a great yielder....but truley AAAA grade....

Purple Dragon.....I have some really good ones hanging right now...should be very good.

I have gone totally organic.....I have an inspector comming to the grow room on sunday to certify my grow space as Clean Green Certified Organic......have not used any advanced nutrients, or synthics, sprays or anything for over 70 days now.

It all bat quanno, kelp, fish emulasion, seaweed extract, rock dust.....etc...etc..etc......the medicine is still flused....but the taste is awesome.
