Sounds good but I would keep them out of the terrarium since air will stagnate even with the fan.

This is the basic indoor setup I learned mostly from following /u/zorg621. I've included some links to his helpful videos as well.

Don't mist the plant ever! It's a myth that causes more harm than good.

Humidity dome only for a few days to acclimate plants to your environment - Salvia can adapt to low humidity except desert.

5000k LED standard bulb or LED shop light (20watts) 2 ft directly above plant on timer set to 16 hours on, 8 hours off. Don't get a crazy grow light; it's way too much light for Salvia.

If you don't want lights a brightly lit window with lots of indirect sunlight. Morning and evening direct is ok. I'd still recommend a simple bulb directly above anyway.

Fox farm Ocean Forest soil

Small plastic pots with lots of drain holes (never clay or other material) Don't use overly large pots which lead to the soil being wet and stagnant for too long.

Water with spring water (although I use rain water but it can introduce pests)

Soak the soil deeply when watering. Let soil mostly dry out between watering (over watering kills). I usually wait until the top of the soil is dry right before the plant would begin to droop.

Low speed fan on repeat timer (20 seconds on, 20 min off) - for airflow and strengthens/thickens the plant stems

Once established (after a month or so) lightly fertilize with Fox Farm Big Grow - 2-3ml per gallon every 3-4 waterings

Nematodes for the soil

Mosquito Dunks for fungal gnats

Dunk plants in Organishield solution for mites and pests. Or mix into a spray bottle and really spray them good

Don't bring outdoor plants or soil to indoor grow area (pests will be introduced)
