and a few more

1) the outside of my fruiting chamber

2) the inside of my mother area (wasted closet space with a 40 inch high ceiling)

3) the axial fan i bought at the grow store (about $30.00 USD)

4) my new 'door', without fan and ajar

5) with fan installed and shut

very ghetto i know but until i added my makeshift door i had ongoing heat
issues with temps regularly running in the mid 80's, with the door added my
temps run in the low 70's now so well worth the bother.

anyway, i know that none of this is applicable to your situation, i just wanted
to show that you are only limited by your own imagination, your own need,
your own situation and your own willingness to keep digging until you figure
it out.

good luck and if i can help out, just let me know.
