The 43-year-old tenant of a storage unit where 266 cannabis plants worth more than £200,000 had been discovered was jailed for 21 months.
Wesley Meaden, of Llewelyn Court, Rhyl, admitted cannabis production at Vale Road, Rhyl.
Judge Rhys Rowlands at Mold crown court said Meaden had been seeking to help his stepson who had a drugs debt.
“I note what you said to the author of the pre-sentence report that you remain of the opinion what you did was done for the right reasons,” the judge told him.
Prosecutor Jemma Gordon said the offence occurred between January and June and the second man had been jailed.
Police discovered Facebook messages between Meaden and him, showing involvement.
Ryan Rothwell, defending, said Meaden had been in the army but discharged after an injury and unable to find work since.
