Filling a tent how do they water?

I’ve been looking on a few sites of people’s setups and I came across one where they had 30 plants in a 2x2x2m tent with 4 lights I think.The tent was full I mean there was no room for a person to get in there at all. All the plants were in soil and hand watered but my question is, how the hell do they manage to water them all when you can’t get in there and reach them all?

Some ideas here. Keeping in mind its a coco site.


For my res...i prefer stir pump with waterfall. No airpump.

You can open the tent wider than just the door. Also, they might have a pump and water each plant individually with a hose.

I like the plant dollies. I think I paid 30 USD each at a hydro shop so they're not real cheap but nice quality casters and construction. In my 4'x4' tent, I reach in and rotate 4 plants around for watering and bonus is you can rotate your plants position in the tent each watering.
