1. Place one of the nutrient tanks under the frame and the trough with the drain in place. Measure the distance from the bottom of the drain to the top of the tank. Add this to the height of the frame from the ground. This will be the length of your short legs. Add two inches to the length of the short legs to get the length for the long legs. Be sure to add in an inch or so of clearance for safety sake.

Cut to of each length:
My short legs are 8"
My long legs are 10"

2. Flip the frame upside down on the fence blocks. Position the legs and hold them with magnets. Note: I positioned the legs lightly inside of the frame so as to give the weld a lower profile. Weld the legs to the frame.

3. Flip the frame right side up, stand back and admire your work!

4. Slide a nutrient tank underneath and a trough with a drain on the frame and make sure you have enough clearance. (sorry for the cluttered background)
