I am intending on doing an indoor straw basket grow. Unfortunately I am short on a tote that will house such a gigantic basket so I'm forced to use polypropylene bags to keep in the moisture and manually open the bags to allow FAE. But my dilemma is stagnant air, I know straw is highly succeptable to contamination for that reason. Are there any ideas on how to keep decent FAE while being housed in the polypropylene bag without the expense of my straw basket falling victim to mold? Will cutting slits or holes in the bag while running a fan indirectly be sufficient?
