I built this cabinet to house a mother plant or 2 but it could be used to grow right throutgh to flowering.
The cabinet runs very quietly and I have used a 5" TT fan and connected a speed controller this makes it even quieter for near silent running.
The running temperatures are very good never going over 80 but are usually around 75 ish which is nice and gives some room for when the box gets filled up.
This is going to be used for cuttings and the mother plant.
I'm running a 250 cfl lamp in there but plan to change it for a 300 in time. There is plenty of height there and the humidity is quite low that will increase with time when the girls grow.
Air in is passive as the fan is so fowerfull active air in is not required. the fan is located in the upper part of the cabinet and the chamber is sealed up and packed with rockwall tightly to remove any sound.
There is a second chamber for attachment of a carbon filter if needed at a later stage.
This project took me 2 days to complete and was pretty straight forward.
As this was just a test cabinet i now plan to build a larger full size wardrobe model for flowering using nicer furniture for this.
Let me no what you all think? any Sugestions ect.
Will post more pictures of fan etc at a later date ok.
