What you think? Made cheap.
cardboard box ($10 from UPS)
tape(had it at home)
coat hangers(had at home)
screen door mesh or some time of mesh ($9 at home depot)
extra cardboard/wood/anything to make frame around mesh (had at home)
muffin fan ($17 radio shack)
so about $36. Many don't even use a fan to pull air in so you could go even cheaper.
here are some pics. a bit blurry sry.
1st pic is screen on top of coat hangers
2nd pic is holding screen seeing how cheaply made it was hah
3rd pic obviously muffin fan
4th pic hole for air to come through
didn't put the hangers up that the bud will hang from. waiting to see lengths of my stems first.
