What would happen if i just throw this little one into flowering?

What's up rollitup!! I got a quick question. What would happen if i were to throw a 1 week old hydro plant into flowering?
The reason i ask this is because i have a very small space i am growing it in, and i was told it would triple in size once thrown into flowering.
Here are a pic or two.

I would suggest waiting just a little longer. You can flower it now but you arent going to get much as you will be growing essentially 1 single cola bud with almost no branches. If space is your issue try LST and topping to keep it low. I've heard everyone saying that it takes until the 5th node for the plant to be mature, after growing a couple autoflowers I noticed exactly that... the plant started to flower at node 5 even under 24hrs of light. So long story short I would suggest waiting till at least node 4 to switch the lights.

my guess it wud stunt and grow a little until its actually able to flower aslightly... and the yiled wud be terrible.
i put a plant in at like 4 inches and it never got tallert than 1 foot. and it kinda gre like it was vegging for awhile until it was old enuff to flower but it didnt flowr much

Actually there are a few people that actually do this on this here website. Some even 12/12 from sprout. I can point you in some what of an expert on this. The master Party Cup Grower. SICC Heres some threads. It's not exactly what your doing but kinda close.

Nothing negative. I have 2 plants veg for 1 week from seed then put into flowering as well as freshly rooted clones thrown right into 12/12. Check out my grow in my sig an you will see. Heres a sample:

Day 1 of 12/12



Around day 35, still another 35-40 days to go
