oh cmon i colored it and everything.
it dont matter if you do it in techni-colour dreamcoat stylee, it wont work.
1. An air tight box will never work for a start, plants need a constant supply of fresh air rich in Co2 in order to breath, grow and give you bud, and to prevent mould/fungus.
2. You need an extractor fan on your "bent pipe" to pull the hot stale co2 depleted air out of the growspace, especially if you plan on using a hid light, but its still necessary even with low power "gay" cfl's.
3. You need at the minimum passive intake holes low down, at least twice the size of the extractor fan being used, these will allow fresh air to be pulled in by the negative pressure being created by the extractor fan.
4. if you want to filter the odour from the air your extracting then you also need to rig up a carbon filter to your "bent pipe"
.
5. FORGET THE BUCKET OF WATER. :LOL:
Im cracking up laughing here, thats made my day.
