Container help

Hey guys, I've just found out that its pretty much impossible to dig holes without a backhoe at my site. Just too many huge roots and hard clay. I'm going to have to put my plants in some containers that I've scraped together. I have one really large 20+ gallon container and I am really trying to figure out which plant/strain to put in that one. The strains I've got are the following (1 of each):

Cheese (GHS) Fem'd
Big Bang (GHS) Fem'd
The Church (GHS) Fem'd
Lemon Purps (The Purps x w/ mystery male from Humboldt Co) REGULAR SEED
Skunk #1 (G13 Labs) Fem'd
ColeTrain (Reserve Privada) Fem'd

All my other containers are about 10 gallons. Which strain would you put in the really large container?? I don't know if I should go with the best sounding strain or the strain with the best potential yield, to hopefully pull down a lb off it. What do yall think? Which strain would you put in the largest container? My site is so remote it really doesn't matter if they are in containers. I'll camoflauge them for the heck of it though.

You seem to have mostly indica dominant strains, but you should put the one with the MOST sativa since it will grow the tallest and finish the latest. It looks like Skunk #1 is about 75% sativa 25% indica. But honestly 10 gallons is plenty for any plant, just make sure the soil is good and they will grow find, even in half that size container

Look at smart pots.

They're expensive but a lot of folks are growing monsters in them.

They come in sizes up to 200 gallons or more.(One guy is getting ten pounders in this size.)
