Well i plan to grow 5 plants in as small a space as possible

That statement has no meaning to Hermie.

You can grow fine herb on a 14" tall stick. Check Oldmac's posts to see that.

You can also EASILY grow a single plant so big you couldn't light it adequately with that 4 x 4 foot Sylverstar.

Hermie sez: "Build the biggest box you can light and ventilate properly, then fill it up with herb!"

There's a lot to read here. You prolly need to research a bit before ou spend $ on stuff that won't work well for you.
