Any bugs, spider mites

[Weezard]

And, da spider mites n aphids.
An' in a week, dere great, great, grandkids!
Nematodes in soil and water
Treat yer girls like critter fodder.

Is it possible to get any types of harmful bugs when growing indoors
specificly in a homade tent/wordrobe mainly bubbler/dwc or type of ponics?

In a word.
Yes!

And without predators, they are prone to proliferate.

Spider mites will ride in on your clothes, hair, under your nails, on the cat, airborne.
Ants will walk in and bring aphids with them.

Store bought soil can come with fungus gnat, white fly, and thrips. No extra charge.

Why do you ask?

An' shucks, son, us farmers expects a li'l trouble.

Just be prepared.

Aloha,
