Little spider on outdoor plant

Hey guys, so this is my first out door grow, I've done a few indoor but my mate moved and gave me a plant so sort of have no idea whether to keep this spider or not.

2 days ago I spotted this little spider and moved him off the plant, angry little bugger he is too. I noticed his back today, putting his front legs up every time I go near.

I just moved the plant back inside to a window because it's been a bit chilly and I'm not sure whether to kill him or let him be.

Thats not a spidermite its a normal spider it should be ok. spidermites are very very small you need a microscope to see them clearly

I don't think it will hurt anything but check your plant really good for other bugs cause sometimes spiders/bugs. Will set up shop on plants because there's food for them .....so check your plants for bugs real close if you don't see nothing and your new pet doesn't start making webs I say name him and let him stick around full time. Lol

He is still there, and one of his mates has moved in on a clone haha. These plants are indoors under 12/12 lighting now, decided I'd do what I know haha. I didn't think it was a spidermite just wasn't sure what to do with him haha.

He doesn't seem to make bad webs, just between leaves as he moves around. I noticed some small white specs that look like whitefly larvae and theres a small issue with ants, I sprayed all their nests outside with rid and now it seems they want to move into my scrog box.

The whitefly larvae I've just been shining an l.e.d torch through the leaves looking for the telltale shadows and picking them off with tweezers. They aren't too bad but if they return I think it's time for some peroxide spraying, about 5-6 weeks left in flower I think so hopefully I won't have to spray anything. No signs of living whitefly.

Plants seem healthy regardless so not too worried about the spider, whitefly at this point would butt**** me though.

spiders are great predators of the asshole insects. let it be....unless you are scared of spiders

I'd also let the spider hangout. Makes my job of managing pests much easier.

I actually hate spiders haha, normally they send cold chills up my spine but these little guys amuse me haha. One of them little money spiders moved on yesterday, I was very amused by his side ways walking until he jumped and I couldn't see him.

I think I may have a gnat problem, lack of air flow most likely, also have a caterpillar issue, well iv only found one but don't want it to be a problem.
