My first grow ADVICE would be LOVED

So this is my first grow set-up, couldn't really call it a grow room. So here's a picture and I'm all ears to any improvements that could me made upon, advice, etc.

Keeping in mind I have almost no more money to invest into this setup.

It's just one 150 watt HPS lamp, and oscillating fan, and a soil pot. The table the pots are resting on is height-adjustable.

It's in a very large, very spacious garage; however, I cannot convert more than this tiny space for growing purposes.

Any tips?

you need to enclose the plant will reflective walls, it will greatly improve the efficiency of your light. Since you have a small light you should also look into LST. You could also add some CFLs for a little added side lighting for cheap. If it were me i would surround the plant with 4 walls painted flat white, pull the top of the plant down until it was horizontal with the ground, add a couple cfls to each side and start flowering.

Remember to spray the floor area with a good pesticide, I use Home Guard from Lowes. I see a new post here everyday, with a newbie grower asking for help with Spider Mites and Pests. Spider Mites can ruin a grow, and they are attracted to Soil, Humidity, Plants, Water, etc.

get three carbord displays like the ones u used at schools for presentations , 4 dollars each and enclose that bitch they have the in white and make a hole for the fan to go in and coverthe top wit a diy reflector, add co2 by talking to her.

Explain this pulling the plant horizontal with the ground.

I'm sorry I should have included that it's already on 12/12 It's been flowering for about 3 weeks already has a nice looking top bud and many flowers with lots of white hairs. Another concern was I let it grow really big I'm worried about the weight of the buds cause sometimes it causes my plant to bend like this....

Not sure how clear the attatchment is but it's like my plant is turning into the leaning tower. I usually just face the fan to blow it back the other way...best thing I can think of.

the twisting/bending is just her response to constant wind. She will be fine with just rotating like your doing.. And the pulling horizontal to the ground is called LST low stress training. Do a search there are some really good people on here that really show step by step grows.
