What supplys should i need ??
For starters? pH meter, TDS/TCC/EC meter, water, seeds, a growing medium, a good pen and some paper, lights, research, information, patience, time, and the notion of being ok with failure, some containers (based on the seeds you'll be using).
im not trying to go big i just want 3 or 4 plants .. Ive watched hours of videos on youtube and im lost ... Do i Need an Exhaust fan ??
You will need an exhaust, not only to move bad air out, but to control odor. They will start to smell.
even if they are in an open environment where they get plenty enough air ??
Yes.
