ok so here is the follow up for the rest of the build.

i framed out the 2x2 with two more in the middle so that i could have a total of three tubs, i then used the mesh wire 3x10 roll. after i had the mesh stapled down i followed the youtube video by placing spacers on the two center framing, instead of cutting up some 1xwhatever, i used 1/2x3/4 trim i looked at originally using 3/4x3/4, but i felt like i could do more with the smaller one meaning if i needed 1/2, id have it, or turn it on its side and use the 3/4 height. but 1/2" was perfect. i cut these spacers to 15" as well, so the same length as the sides and centers, then i once again followed the video and used finishing nails to hold it down for when i added the 1x3s

from there i cut the 1x3s to 15" as well and centered them on the spacer and ran two screws into it, be careful, even drilling a pilot hole, the spacer may crack. i had a couple that did but due to the pressure of the screw it will be no factor..

finish it out like the video to build it, spacing is pretty arbitrary between shelves, i went with 6 1/2", i am doing a watering system so i can keep it tight, i have about 2-2 1/2 between the bottom of the tubs to the next lower level. i was able to make 6 levels standing 48" high...

now for the most helpful part, the supply list,

16 2x2x8'

2 2x4x8'

1 3x10 roll wire mesh

2 0.5x0.75x8' (square trim)

2 1x3x8'

18 dish tubs

box of 2 1/4 wood screws (get the self drilling ones, saves time so you dont have to drive pilot holes, not one pilot hole was drilled other than for when i was working with the trim)

box of finishing/wood floor nails

hope this helps someone! i had a lot of guess work for sizing and measurements,
