How Many Plant?

Hi guys. First timer here.
this must surely sound ridiculous to you guys, but my grow closet is 37 CM deep (1.2 feet), 42 CM (1.3 feet) broad and 170 CM (5 feet) high - and my question is naturally; how many plant i can grow there?
Does have anybody have experience with this sized closet before?

I hope to grow 4, but even i think that might be impossible, so i guessing 2 tops.....But some feedback would be highly appreciated.

I use a CFL 105 Watt with reflector and have white walls.

wow. small space. but small spaces are my thing. see my grow journal.

i had 4 plants in the same size space but, i used LST to keep them low, also. if you have five feet in height, this is good. get tall, but narrow plant pots so the roots can grow down but not out.

if i were you, when it came time to flower, i would strip all the lower and side shoots and just concentrate on the main cola. that way you could raise the shorter plants on blocks, if needed, and the 4 colas would receive equal light. good luck.

Its good to hear from an expert. it brings great comfort to know than its possible with so little space as your grow. Mine even looks a bit bigger.

Im thinking about concentrating on two plants - how many cola's should a try and go for?

- do you have any other small-closet-grow expert tips?
e.g.:
how many gallons/liters where your pots?
