Was it similar to the original ? I would gladly run something 20 weeks plus to be able experience that again.
Mine took 13 weeks of 9/15 light. It could have gone another 2 weeks I guess. 10,000 K fluorescent and a little uvb bulb at the end for 2 days.
I never had '72 CG so no idea, but I ma guessing this is legit. I had '79 CG and it was crap compared to this. It did have that incense smell to it, but was pulled early with white seeds and more density that this '72. This '72 has a bit of the incense but is more complex, not really that 'church' taste or smell.
People that did have the early CG seem to agree this is legit. 90% of people that smoked CG back in the old days had a more indica type than this. Heavily seeded as well.
This stuff weighs almost nothing, explaining why it went away. Money rules the world.
All the phenos are quite potent but I think this last one was the most potent. Runt plant so I did not clone it. Oh well.
