What up captain. How many plants you runnin in there? Do you have pots? I recommend 1 gallons to start - 3 gallons for veg - 5 gallons for flower. How will you deal with runoff? I would consider putting a tray on a stand in there if it will fit. You can setup the table to just drain your runoff in a bucket underneath the table. As far as nutes go, it's all about the base. Start with a solid base and go from there. Try the big brands and see what works best for you. Botanicare pbp and advanced sensi bases are very solid. From there I would add something like bud candy/sweet/humbolt honey - just some kind of sugars - and some type of enzyme ie hygrozyme. Humic and fulvics are great additives but can get pricey if you get em in the hydro store. Keep it simple. Hope it helps.
