    I was going to set up a 400w MH/HPS grow tent for two or three plants, but I'm liking the idea of less heat (means less noise from fans etc...).

    - What would be an equivalent T5 Fluorescent Lamp replacement for a 400w MH/HPS in this context?
    - Can you use T5 Fluorescent Lamps for veg and flowering?

    Thanks guys

    Yes you can use t5 for veg and flower.I would rather you veg with t5s and flower with the 400 but the choice is yours not mine.I would say you need around 8 bulbs if not more to add up to a 400 watt and it still wont penetrate like a 400 hps would.Good luck with your grow.

    Thanks for the info. 8 bulbs it is. You can simply use the same 8 bulb setup for veg and flowering and simply switch to 12/12?

    Do you take a major hit in yield per plant when you go the t5 route vs a 400w mh/hps route?

    Very major.It will probably give you half what you would get using the 400.You can keep the t5s close but they are still floros so they will not penetrate like the 400 will.
