I recon that it can be done.

Just get pots that aren't that tall.

Try and make them the biggest volume possible, but with the least height.

So, let me try this mental excercise:::
23.5 inches... let's take it down to 20 for "lee way".

Let's say you get a 8 inch tall pot...

Then leave 8 inches between plants and the screen...

That's 16 inches.

Now, you've got 4 inches for your lights and canopy.

Hard? Definitely.

Possible? Also definitely.

I say go for it!

If you get pots that are less than 8 inches tall... well, you see where I'm going.

Go for it!
