Pineapple Express Auto - When will it bloom?

I don't grow autos but I got a free seed, Pineapple Express. Description says it takes 70 days to bloom but when do these typically start blooming?

It's under 24 hours of light with the rest of my veggers. I've read in the past that autos wont necessarily bloom if they are getting that much light. I'm just curious how big it could get and if I should transplant it in the future. I started it in the container it is in now, which is about a gallon. I want to say it's been three weeks but I started it after I started a bunch of other seeds that are now over a foot tall. The auto is only about five inches tall (measured from the cotyledons).

I've grown G-13 labs Pineapple Express 90 day autos on 2 occasions. First time was inside in a 7 gallon Smart Pot using 18/6 the whole time, veg & bloom with 400w T-5 fluorescent, replacing 4 of the blue lights with red after bloom started. Around day 20 it was 5 inches or so tall. Day 35, it was 1.5 feet. Day 35 or thereabouts was the first time it started to show flowers as well. Harvest at day 93. Yield was 110g, just under 4 oz. I LST'd it to look like a reversing S curve, still it was 2.5' high

I've got one in my outdoor garden right now in a 5 gallon smart pot, been outside since day 1, today is day 91. It's 3.5' high, but it looks like the yield will be a little less, say maybe 2.5 oz. The tops look like they're ready, but some of the lower nugs still need a couple of days.

A lot of people use 24/0 and claim good results. I've used 20/4 with some 60 day AKR's, but have never tried 24/0. I don't know, I'm old school and feel there's dark at night for a reason.

FWIW...In the future, plant your autos in the pot they will finish in. DO NOT TRANSPLANT THEM. Every time you transplant shocks the plant to some degree. The plant is going to automatically finish in a set period of time. You just decrease your yield by stressing it unnecessarily.

Good luck

That's why I started it in the gallon container so I'd only have to transplant it once if necessary. I'm very gentle with transplants. Wasn't sure how big it would be getting and I'll be surprised if it gets that big (over 3').

My regular photoperiodic plants I want finishing around 2.5 ft and they'll be in 4 or 5 gallon containers. This is all indoor though. Thanks for the input.
