I've got an, since my floor is tiled I'll be using sliders under plant trays to aid moving. Once flower starts I typically have to crawl on hands and knees to feed. This 1st run will be 15 plants so I should have plenty of room
On my first few grow I used plant casters with the larger saucers under them to catch any runoff or drips. To keep them tidy I popped on individual pot scrog contraptions. Basically 3 poles and a larger round top. It helped hold larger branches up and kept the plants intact basically. I used to play musical chairs with the pots with ease. The additions were around $20 each plant/pot but payed itself back immediately with the time savings.
