Hello fellow growers. Just walking down the aisle of our local dollar store and came across these clear plastic bowls. My grow is on my mind 24/7.lol I was wondering if placing these bowls upside down over my seedlings to first week or so and running a tube into the bowls from the top connected to a diy co2 mix. Is this just useless or will I benefit from it. Bowls are not completely sealed so fresh air can enter as well. Just wondering? It would be easy enough to put together. Thoughts ?
