My indoor zippers broke, could I leave it like thi...

No it won't cause you problems with growing plants up to Flower. Post Veg air will flow freely in and out of the tent, thus the smell will escape. You can fix it with duct tap as a temporary fix.

[McGyver opening theme] Duct Tape is your best friend until you fix it. ^^ No light should disturb the sleep of your plants at this stage (it could lead to an undesirable return to the vegetative phase).

Try and repair the zipper. This happened to me on a backpack and I used a pair of pliers and squeezed the zipper back into working order. Like others have said the light leaks can cause issues if the plants are Photoperiods, Autoflowers don't really matter. The other thing is that if the air in coming in without a prefilter more dust and pests can get into the tent easily. www.youtube.com/watch Good Luck!

It will cause problems when the light leaks in to the tent on night-time. The plants require full darkness, and even a smallest leak of light in to the tent may prevent the plant from flowering at all, or even stress them from females in to hermaphodites. If I was growing autoflowers I wouldn't stress it that much, but with photoperiods it's pretty strict with lighting.

You can still manage autos with light leaks but photoperiods are gonna need better. If those ladies are photos you might be able to limp through duct taping the gap until you can get it resolved.

It will create problems if there’s light leaking in the tent. 1 candela is enough to trigger photosynthesis. 1 candela is the intensity you get from a candle at 1 meter on a sheet of paper.
