Here are a couple tips for you:
Please take your lid (with the plant inside) out of your unit to air out the roots for 20-30 minutes every 8 hours. That way, they will be able to breathe while the bubbler is not functioning.
Please take a cup and manually lower your Grobo’s reservoir volume by 10%. This will give your plant roots some air time when it’s back inside the Grobo, allowing for it to receive oxygen.
Keep the door shut during the day, the biggest thing right now is to not let any extra light in when she is sleeping. Missing out on her usual light is kinda like having a cloudy/stormy day for an outside grower. Not a huge deal.
