How to make a Unistrut rolling bed for your indoor garden

Shoutout to Collective Elevation for the inspiration and Greg Larson for the additional assistance. Here's my attempt at making Unistrut rolling beds using a 4x8 flood tray and a Grassroots 4x8 which we sell through our website.

Setting the spring nuts with the spring downward will hold it in place correctly

Using the corner brackets help square the bed box just 4 outside corners 16 spring nuts 16 bolts it is worth the expense. Deep nonslotted is stronger you will have to drill the caster attachment points. Nice work tad

for loading in the spring captures, loosely bolt it to the upper piece 1st, then pull it down to slide into bottom slot, you can then slide rail into position and tighten off. if you need heavier gauge uni-strut or without the "speed" holes all the way along, electrical wholesalers stock it.
