Have you sucessfully grown cannabis in the past? Do you have any practical growing experience? Don't you think that after what you've already been told that you are likely barking up the wrong tree?

If all you want to do is dick around with the ladies, I'd say go for it, as it will be a learning experience regardless of outcome. But if you are in need of the best meds you can grow...this experiment will set you back a few weeks or more. Stress and 'training' delays harvest dates.

Just because you are growing vertical, you will not cheat the 'grams per square foot' goals, in case that's your objective. But it is a great way to lower yield and delay harvest, IMHO.

Good luck with it, But if these are your meds, I'd learn to optimize my grow before attempting an experiment with the wrong equipment.
