There are just 4 holes punched at the sides.
1. Don't they need holes at the bottom too? I'm suspecting water might be pooling at the bottom, since the tomato plant's leaves are warping.
2. Since it's a plastic bag, would making more holes just make the bag tear apart easily? How to make holes safely?
3. An earthen pot allows breathability, so to simulate a similar effect for a grow bag, would it help to take a pin and poke tiny holes all over the sides of the bag? (not too many that it'd make the bag tear, but just enough to allow some aeration)
