KIT (as of now)
4x4 tent, SF2000 Light, SF 6 in Fan, SF Carbon Filter.

Plan on only growing 3 autos in soil at a time, due to the fear of the smell factor.

Questions

1. Will the SF 2000 be sufficient for the 3 plants?
2. Will the SF 6 in Fan and SF carbon filter solve the smell factor?

Appreciate any help anyone has to offer.

Your light is 200 watts.......it'll be less than adequate for a 4x4 tent. For maximum yield you need double that at least.
A 4x4 tent is perfect for 4 plants.........one more plant isn't going to affect the smell any more than 3.
Your fan size is fine.

hey welcome to rollitup . the 6in filter fan should be fine for 4x4. the light will be alright for starting out ,but you will need more watts in flower in a 4x4
