Watch my first babies grow, help me out (Pics)

Around a month ago I bought some Nirvana Feminized Big Bud seeds from Gypsy Nirvana and after 2 weeks slowly building a small grow cabinet I got started.

Im using a 125w cfl for my veg stage which I will start flowering at around 5-6 inchs as my grow cabinet is only 25 inchs high. Im thinking my only option is some lst'ing or to do a scrog.

My main mistake so far was growing them for the first 10 days inside a cardboard box with no reflective material inside the results of 10days growth are in the first two pictures below.

Now 14days into growth and just 4 days in my cabinet they have grown so much and fairly quickly.

Any advice or tips will be a big help to me, im a newbie and could do with these plants producing some bud as dealers around here sell some shit stuff and paying £20 for a henry is starting to get annoying.

I have a 150w hps but maybe I will just go with a 200w cfl for flowering as heat issues will occur my cabinet is very small only measuring 20x20x25.

I have a powerful 120mm pc fan for exhaust and passive intakes.

a 150 watt HPS will put out less heat than 200 W of CFL, and will be doubly so if you can remote the ballast, which usually isn't too hard, just lengthen a few wires is all you really gotta do.

Your grow space is pretty small, your going to have temperature issues from the radiant heat more so than from direct heat, hopefully your fan is up to the task, get yourself one of those remote temperature gauges and make sure things don't go over 30C (85F).

Read this a few times too https://www.rollitup.org/view.php?pg=faq

your third and 4th pic are interesting. how are they already so bushy?
this is mine about 5 to 7 days in (it has only been on 24 hour light schdule for almost 2 days now)

Dude I have no idea how they are growing bushy already but it suits me fine in a small grow space.

lol,
i hope mine starts to get bushy. its just really damn tall for some reason... today it has been in a 24/7 light cycle for 2 days now... so i'm hoping within a week i'll notice more bushy-ness and less height.
anyway your plants look good

So far so good dude, keep up the good work, i've just started my first grow, check it out if you like, could keep in touch about the grows dude

My plants are finally growing rapidly, My grow space is very small so I was thinking of starting the flowing very soon.

id give em atleast 2-3 more weeks min before flowering
