Not sure how to proceed with this strain

[I'mOne]

I have a Romulan grapefruit mom I have been cloning, and I love the smoke. I grew out two more and since I grew them out in a green house they stretched. There are no real bottom leaves. I tried cloning them but they are so far in flower it's not working well. These plants are probably six weeks into flower. The trichomes are not milky yet.
I would like to re veg these and cut clones, flip a clone and breed the Romulan grapefruit plants to each other. The older mom has some clones going now. They are just making root, so are a few weeks out from being big enough to flip.
If I bring these big plants into the house, so I need to slow down the nutriet schedule and bring them in and out them on a lengthened light schedule? Will they stay in bloom if I try this?
I usually put my mommas I plan to re veg on a 16 or 18 hour schedule and they re veg easier when the time comes. I'm thinking of bringing these big plants inside and trying this...

I am not positive of the best light schedule to reveg. I always did 24 until the reverted. Yes this would work. How quickly is another question. I have harvested a plant and revegged it, so there is no "dead line", so to speak. Any time is a good time.

 

[I'mOne]

I may bring them in if it looks like weather is getting cold, if I put them on my 20 hour room I wonder if the flowers will still mature?

 

[Pat Puffer]

No flowers will not. The plant, once exposed to 20 hrs of light will stop making bud and revert back to vegetative growth.

 

[I'mOne]

I had some flowering plants before that I prepared for reverting by gradually increasing the 12-12 over to 13-11 or 14-10 ...it seemed to make them transition easier and didn't affect flowering that I could tell so I didn't know ...exactly how much daylight they would take and still finish the BUDS

 

[Regrowth]

I think I spotted a photo strain before that claimed it could flower with 17 hours light. Someone could correct me.
How much daylight is probably strain and environment dependent.

 

[I'mOne]

Yes I had one freak that started flowering when I dropped from 20 to 16 hour daylight.

 

[I'mOne]

She was an f1 and pumped out lots of beautiful flower that tastes like shit and has no real quality to the high.
Lol.

 

[I'mOne]

Here they are, they re-vegged and one is farther along than the others. I will be cutting clones as soon as I'm sure they are ready

 

[I'mOne]

I went on and cut clones today. We will see how they do. I cut two from the taller plant and four from the lower plant. I'm trying cloning in perlite this time instead of peat moss

 

[Pat Puffer]

Keep your temps up. One crucial facet of the environment i never kept in check was the temps which probably lead to a ton of failure.

80° seems to be the neighborhood my clones root best at. Just personal experience.

 

[I'mOne]

Oh wow...yes it's gonna be cold here for the next week! I have a seedling heat mat under them

 

[I'mOne]

Checked this morning five out of six look perky. One of the cuts from the tall Pheno doesn't look great
