You won't be growing any plant seed to harvest in 7 weeks sorry to disappoint you.
I wasnt counting on it, figured its unlikely. But why are multiple seed venders claiming false times? Gelato says 7 weeks "seed to harvest" for nyc diesel auto. Just found another vendor, same strain claiming 45-50 days "seed to harvest" which would suggest it could be as quick as 6 1/2 weeks. Are they all just straight up lying? Is it really impossible for "any plant" to go that fast seed to harvest?
Btw, im not arguing with you guys. I absolutely believe there is nothing that fast, im just curious why these reputable seed companies have to lie about. They really are stating it word for word "seed to harvest".
I do think "at least 10 weeks from seedling" is a bit of an overstatement though. Maybe for the average auto, but there has to be some faster than that. I grew thundefuck for 3 years in dwc. From a rooted clone i went 10 days in veg and 50 days in flower, 3 to 4 oz per plant. Very few amber, but definitely not immature. If a photo period can go rooted clone to done in 8 1/2, how can a fast autoflower need minimum 10? I realise thats still very far from 7 weeks seed to harvest, but minimum 10 from seedling sounds excessive for a fast autoflower
