My inadvertent record is 2100 g wet, or 15 oz dry in a DWC system.
It was inadvertent because a single WorldOfSeeds NorthernLights x BigBud refused to start flower until 10 weeks after sprouting.
At first, it was one of several plants in a 3 ft x 3 ft tent.
But after the others were harvested I let it have the whole tent to itself for several weeks.
Finally, I couldn't afford anymore time, so I harvested it about 2 weeks early, after 17 weeks total.
It is actually quite good, making me wonder about whether all our trichome harvesting rules are really correct.
The name was appropriate, because I've never had bigger buds.
