Hello everyone,

I'm currently propagating a few philodendron/anthurium/monstera cuttings on my dorm windowsill in cups of sphagnum moss covered with plastic bags. The only issue is that my roommate likes to keep the room kind of chilly (65 degrees) and I believe this is slowing the root growth of my cuttings. Some of them just will not root.

Anyone have any ideas as to how I can cheaply warm up my cuttings on the windowsill without needing to change the temperature of the whole room?
Thanks!

Make a prop box with a lid you can open and close and get a grow light that will radiate heat

It would also help if you provided photos of your props so we can see the size we are talking about

There are heating mats made for plants.
