Advice for growing in opaque pots?

[NewBloom]

I'm transferring a cym to s/h soon. Finding a suitable tall, clear pot is proving to be impossible on the ground. I have the orginal, bottom draining plastic pot it came in and might have to wind up using it if finding a clear pot doesn't work out. (I've checked the food storage and office supply sections of WalMart for containers that could be repurposed. No luck there.)

My concern with the opaque pot is that I won't be able to see how the PrimeAgra is wicking or if there are any root problems beginning.

Have any of you used s/h culture with opaque pots? Is it a challenge to do versus the clear pots? Your advice would be of great help.
