2 to 3 weeks I believe is average for pistels, if you haven't left it to veg long enough to mature. The proper way is to leave it to veg until you see proper pre-flowers, that way once put into 12/12 it should pistelate almost immediately. Or at least within days lol
Big Bud is a commercial strain from the 80's and not high grade. I started it cos I didn't have anything else and wanted to fill my space and it also was a freebie when I bought my Fruit Punch. Aye the yield should be huge compared to the others, but sadly not as strong, as tasty or as expensive to sell. It sells as standard.
The other one that I have started is similar to Big Bud (Budziller). Except the Budziller is proper high grade and set to be the most potent out of all my strains at 24% THC and easily worth £250 an Oz. The yields I'm expecting to be similar to the Big Bud.
Something for you to think about? Only cost me 7 quid for the one seed
I should get plenty of clones out of her too.
My intention with Big Bud, is to keep me in smokes for a while, while I'm waiting for others to harvest
