First, is to purchase the tubs. I use 22gallon rubbermaid tubs. One may choose to use bigger tubs or smaller tubs depending on preference and use. I can flower one decent plant per growbox. Any brand will work, but I chose Rubbermaid because they lay the flattest and sturdiest when topped on one another. My first growbox is made of blue colored tubs spray painted. These tubs are brown. The darker color the better to keep the growbox dark during the 12/12 flowering cycle.
Each tub cost $7.45 from Wal-Mart for a total of $14.90 before tax.


While at Wal-Mart I also bought my CFLs; each is 26 actual watts (1700lumens). I will need 6 CFLs (156watts/10,200lumens) and these are the biggest you can fit in 22gallon tubs.
A 3 pack costs $7.58. I purchased two for $15.16 before tax.


The next step will be posted very soon...stay tuned!
