is my first grow room suficent

any coments an sugestions would be mutch apreciated/iv got a 7ft/5ft /6ft high room .im using 600w hps/ intake fan an exaust fan witch both run on a unit so when my room reaches a sertern temp eg 28 degrees they both kick in to cool my room to the setting i desire.my room is covered with black and white sheeting and air tight to stop any vermin getting in and unesesery odours escaping. at the moment iv got 5 little ladys that are 2 weeks old and are doin ok i think i aint giveing them ant newts at the moment going to wait till they go on a 12/12 . i am a bit confused how high to hang my 600w hps from the top ov my babys and how often too water .at the moment im only giveing them 200ml every 2 days and there in 10 liter squre pots. and sugestions plzzzzzzzzz:thumbsup:

do you have the room sectioned off?a 600 watt light works great in a area 3x3or 4x4.also how far you keep the light from the plants depends on your room temps and canopy temps,place the back of your hand over the top of the plants and when you feel heat from the light.a 600 generaly if your temps and ventilation are up to par you can get it to 12 inches

cheers for that mate temps an ventelation are up to spec so ill try to lower my lamp a few inch a day :thumbsup:
