help please newbie

hi,
i have 6 plants in a good sized sealed off plastic room i made for them in my kitchen. I have a fan up top blowing out of the room for exhaust and a small door for myself to get in towards the bottom for new air to come through. The ventilation works well. I am running a 600w above them. I was wondering if it would be beneficial to buy some small flourescents to throw underneath my plants to get some light below and under the tops. What do you think? any suggestions are appreciated. thanks.

More light the better IMO

but some t5s for the corners

i bought daytime flourescents 8 of them 2 for each corner. taped on my pots.

blue fluorescents hung in dark corners of a flowering room that is predominantely hps are benefical as a mix of light spectrum is good.

whats important is that a 600w lamp will cover an area between 0.75m and 1m square so if your space is bigger than that you need more light. saying that as stated extra light is always good it follows that what you get out is equal to what you put in. if you are thinking about placing light underneath then this is pointless plants absorb there light from the upper surface, they vreath through stomata on the underside and you may dry them too much.....
hope this helps
