    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.

    u wont cut back in yield using the t5s during flower if u have scrog up because than penetration doesnt matter all of your buds are even getting light i just finished my grow using 2 t5s worked great!

    Scrogging is the way to go with T5 and flowering. Just use the proper spectrums. I'd personally go with the HPS though for flowering. T5s are absolutely wonderful for vegging though. Theyre low heat. Low power. No noise. They'll surprise you with their veg power.

    My t5 fixture has white light bulbs for veg and more f a red light bulb for flower. So you can flower with it im sure. Definitly better to go with hps or something stronger

    150W mh. For veg(low heat, great penetration). Hps for flower. I like to keep things uniform. T5 seeds and clones. I remember when i tried using spot lights!!! I've came along way since.

    IMO you should only choose to flower with T5's if you want quality over quantity. Yield is possible but it takes a good grower to get it. It also cost a bit more to get the right bulbs for the spectrum. You can see what is possible in my sig links
