Depends what you want to do. Yes using the sog style will work in the net pots. Your system is for pot growing not tomatoes. But if all you have is that one HID and you can get the aquafarm buckets then 2-4 aquafarm bucket plants will have more yield than 6 sog plants.
You wouldn't be doing a true SOG without about 4 times the equipment because the purpose of the technique is to have a harvest every 2 weeks.
It looks to me you are just getting your firt grow together
