Some say don’t top but some growers can get away with it. There are so many personal views it’s hard to get a consensus. Just ask about lights/nutrients/IPM ect. and you’ll get the gambit, who's right and who's wrong? I say experiment and learn from them.
I just ordered 5M for around $20. I think its cheap insurance, not a complete IPM program but takes care of what I can’t see in the soil. I use blue and yellow sticky traps to tell me whats crawling/flying around.
My worm bins, 5 gal buckets are outside because of the smell and I get lots of bugs/critters. I don’t want to use this for my indoor plants because of eggs/larvae. How do you handle castings raised outside?
