About to start a new grow need some advice

Hey people I've not done a grow now for a while and wantsome advice. I have two 600w lights and a 2.4m x 1.2m grow tent and 2m high.

I want to fill it up and have a decent size grow but also does the soil used make a massive difference? I used from a gardeners place like a fairly standard one I'm guessing and I used all bio bizz neuts throuought the grow. I want nice big buds and would like some recommendation on what i should go dodown how many plants should I fit in this size tent?

Also pot sizes, I know the bigger the better but what would be a good size? I've used buckets in the past with holes in and I have some pritty big ones too

I am more than likely going To grow white widow and more than likely from greenhouse seeds

Sounds to me like you have room for 18 plants, I grew 9 in a tent half that size and barely had enough room. I liked the 5 gallon smartpots better than buckets and think that soil quality is very important to the grow. Good luck shenko, if nothing else you're about to learn a lot about our favorite plant!

I've done ww a few times and I do like it but obv there are people out there who are a lot more advanced at growing than me so a few tips are good. Should I just use bio bizz or is there a lot better ones which will make my yeild bigger? In my 1st grow I ever did I used mirical grow and my plants seemed to grow bigger and better than using bio bizz then bio bizz in flowering, I need some decent neuts
