Forty I'm not sure if you're replying to me or 303 - if you go White Widow you'll be happy. I don't know 420-seeds version but White Widow is an amazing strain. Potent.
"you can leave lights on 24/7 and they still BUD?"
Yes, they flower after a certain time regardless of photoperiod. I kept mine in 24/0 for 5 weeks in my veg room then put it in 12/12 in my flower room. 20/4 is whats often recommended but they flower under any split. Taiga is excellent to grow, not a bit of trouble. Hopefully the high is as nice.
