T5 tubes have a better light spread than MH but MH is most suitable when you want an open top tank. Not to forget, MH is harder to mount(ceiling), so I opted for an easy way out.
I would be great to post the plant growth result of your 70w MH and venture bulbs because I was told that not all plants grow well in MH because of the spectrum unless you buy expensive ones like arcadia bulbs.
