building my new grow... advice and tips welcome

This is my plan if any one has good ideas will be appreciated.


Flower room

Size: 1.5m x 1.5m x 2.7m
Lights: 2 x 600watt hps
Ventilation: 6" intake growlush fan and 6" outtake w carbon filter and silencer
40cm fan for airflow around plants.
Plants: 2 large plants

Veg room

Size: 0.6m x 0.6m x 1.2m
Lights: 130 watt cfl
Ventilation: 4" intake and out 15 cm fan for airflow around plants
Plants: 2 + 1 mother plant

Planning on vegging between 4-8 weeks as hight isnt a problem pluss longer veg higher yield

Any thing I can do to make this any better

Perhaps add some light to your veg room. Maybe 2-3 lil 23-27W CFL's to get coverage if you aren't going to give them more then a 130W single bulb up top.
Just my 0.02.

You might also want to up your ventilation in your flower room a little.

I would like to add more in the veg room but space is abit of issue.
Ill try work somthing out.

How much more ventilation would I need in the flower room?

Why not run one 600w vertically in that bloom space? with 2 in their your heating up real fast. is it a tent? Seriously, check out vertical growing...more bang for the same buck

When doung active exhuast and active intake,the untake fan needs ti move less air than the exhaust fan in order to maintain a negative pressure envuronment.

Your going to have a hard time growing two really big plants with just a 130w cfl. I suggest putting one of those 600w in veg until your ready to flower then move it back. With just that cfl even with a 8 week veg those plants arnt going to be big enough for to cover two 600s

Im adding another 55watt cfl im hoping that will do the trick.

Isnt the general rule to 50 per sq f

Correct 50 per sqft

Im getting about 47 so just under with 185 watt.
Going by the math shouldn't that be enough to veg with

It definetly wouldn't hurt to get some more light in there. But if money is an issue that will suffice. People have gotten away with less.

Money is abit of the issue but mostly space

And if I remove what I have and put a 400 or so ill have to spend more on extra intake outake fans due to heat.

This is the space I have
