Mass drying in garage

Should be fine though I would try and strip as many large fan leaves off as possible just cause you vut a plant down dont mean it stops giving off humidity and if you have very large plants while drying thats going to push your humid through the roof along with any smells in your garage and dusty damp kind of smells will permiate your bud just like when you dry plants in the loft they get tyhat distictive flavor. My advice if your growing outdoors why not dry outdoors too all you need is a tarp and somewhere to hang it over then string up your plants spaced out leave gaps at either end for the wind to blow through and dry your buds as you grew them :) in the great outdoors :)
