5L jerry cans as hempy buckets?

[OneMorePuff]

I'm planning a coco/perlite hempy run using 5l pots.  It'll be a pheno hunt with reg seeds so I don't want the pots too large as I don't know how many plants I'll be flowering out in my 4x4. 

 

I'm thinking about using these 5l plastic jerry cans - 

 

 

 

Obviously I'd need to cut the top off so it's flush, and put some duct tape round the outside to block the light, but I like that their tall narrow size means I can get them in really close together side by side under the T5 for vegging.

 

Plus I'm cheap so 16 for £20 is attractive, especially as the the ones I don't use as hempy buckets I can use for mixing up nutes, storing RO water, that kind of thing.

 

I'm assuming the tall narrow size isn't an issue for hempy buckets, as I see people doing them in 2l bottle and getting good results? 

 

I guess I'd just start them in a small starter pot of coco/perlite or root riots, and then once they're rooted out, straight into the 5l hempys so the roots can start working their way down to the res?

I use five litre square bins from the pound shop , works well.
