Dude MH is great but the amount of energy isn't worth it. You keep a 4' 8 bulb T5 close to the canopy that you are maintaining and keeping at an even level: Your results will be CLOSE to using a MH, minus paying for more energy and having excessive heat. I veg the top 2' of my room and flower the lower 6'. The "Dual Spectrum" works still
How do you pay for more energy with a 400w mh vs 432w of t5?
Here´s how i would figure which system to buy.
Do you have excessive heat around your parts and no way to properly went a room?
Then t5 might be for you. (the heat Is the same, but its more spread out.)
Do you have a low space? 4 feet and less in height?
Then t5 might be for you.
Do you dislike constantly fiddling with your plants every day? (lst and scrog.)
Then h.i.d might be for you. (with a light source further away and more space to do everything, gardening is less work.)
Do you have a at least 4 foot tall space that you can went? (whether box or room.)
Then h.i.d might be for you.
t5 and h.i.d are sorta comparable but t5´s are more work to get almost the same. (h.i.d outdoes them.)
