Hey James,, Whats happening..
I reckon dig a Hole for each one and put a Black bag inside it.. so the water doesnt escape into the surrounding soil.. Make good drainage but also so it retains water as I am not sure where you are in the Canaries but some places have more rain than others.. SO check the average rainfall..
I will be coming over in Feb if you are still there, I am looking for a Room and a Partner so let me know if you need any help, I am into crossing strains, producing new Hybrids and various other guerilla moves.
Also use a slow release feed in soil like a powder feed so it give the plant enough nutes other wise you will be mixing every second day outside.. rather use slow release.., maybe mixed with Straw and Perlite not too much straw! Straw is cheaper and it works well!
Good luck..
