Unfortunately because its a cupboard room its not very big, and i can't put in venting.

The size is about 8ft in length 4.5ft in width and about 2.5 metres high.

Slightly raised platform kind of area inside the room not included in the length its about 2ft wide and about 4ft up from the floor.)

Bit of a crush i realise.

Im growing: Arjan's Ultra Haze No:1 ( Toked it at the 2006 cup)
Kali Mist ( Toked it in Amsterdam)
G13xHashplant ( G13 amazing strain.)

Also Im not entirely sure how much i should be watering them at this point?

Thanks.
