I would say the 2lbs per 4x4 is closer to a myth and only achieved by certain growers every now and then.
Frosted fan leafs and stems do not count as weight. Damn near every bud I see on here needs trimmed better.
When I pull it out if the bag it goes strait into the bowl. Idc how purprle or frosted the fan leaf is, I want the buds. Hell if you can squeeze the buds and it collapses, I dont want it. . . too much larf your weighing.
The closest I've gotten to 2lbs in a 4x4 was with this strain. I had no co2 and this was a year ago. Ive popped 3 more seeds since and still not this same pheno.
The buds in this pic are what urs will need to be like if u want to hit weight. I had baseball size nugs under baseball sized nugs.
Imma go with anthem and say something is off.
