PC grow box Northern lights or short rider

I have a 27" pcgrowbox but i was wondering if the nirvana northern lights would fit in it or if i should go with the short rider. This is my first grow, so i don't want to have to do anything complicated and make it curve or something

which one should i go with

Either strain will fit, but the northern lights will require more training and trimming, which it sounds like you don't want to do. Low rider strains have been grown successfully in PC cases, but don't expect a substantial yield from any strain in one. If I were to ever grow in a PC case, I would set up a seperate box for vegging a mother plant, then flower clones in the pc case, so you could harvest more often, and not have to wait months in between grows.

My opinion would be to spend a couple hours reading up on these forums and any questions you have will most likely be answered already. Good Luck!
