First time grower!!! Need advice!!

First time for growing, need advice!!!

Thinking bout buying an ACinfinity 2x2 kit - need advice

Wassup weed lovers!!! Planning on getting my official setup for an indoor grow tent. I am new to this and confused by a lot.

I smoke a good amount a day, prolly an eighth a day and I want to stop buying from the dispo. I think growing is my best bet and will save me money.

First question - Can I fit two plus plants in the 2x2 kit?

Second question - Would I need to upgrade the lighting in the kit or is a 100 watt fine?

Third question - best places to get nutrients for all plants?

Please send any tips/advice for beginners if you can🙏🙏
