Spider on plant any ideas??

Hi i saw a spider in a web on 1 of my plants tonight, im in the uk, it was small yellow with a black bum and black legs i say small but was able to see it hanging there 3 ft away, ive had mights ages ago but this wasnt like them?? ive tried to get picture but it never comes out right even through mag glass, ive also googled it to see about spiders on our plants but it allways just goes to spider mites, my main question is other then mites should we be concerned about spiders on our plants ???? im now going to search through my plants to make sure theres nothing mitey for sure, i hate creepy crawlies in my area!!!!

Just a guess here. But I'm gonna say NOT GOOD. Even if it is just a spider, you have to ask yourself.....WHY the FUCK did he choose your grow area for his home? Spiders like hot, humid, dark places that have a great food supply. Food supply being other bugs and insects (which should NOT be in there). I fucking hate spiders on top of that anyways. I would go through your shit with a fine tooth comb and make sure it's CLEAN. Remove any and all webs. You DON'T wanna smoke "spider-butt-silk" now do you?

Hot Shot that spiders ass....it won't come back...keep one in your grow area and you won't see any more critters invade....

you sound like you like em as much as me!! im looking but just cant see any thing else out of place, just have to get mrs mop out again and get cleaning,
oh yeah your right i dont want to smoke that, but i might name my next grow that, cool name

Vacuum that little scary bitch up.

looks like that was the only one!!!
now i can get back to killing the plants myself!!!! with my defunct ph pen

Spiders will catch the bugs that may want a nibble some of your leaves.. So it could kinda be like the body guard of your garden to the insect world... but with that being said I have one 2 and i just killed it lol mine was brown and about a 1/4 of an inch. it really liked sunning under my cfls.

I always thought spiders were kind of benificial to your plants because they dont bother them and killinsects that will harm your plants.

I hate spiders. If I kept one in my grow room id be so paranoid every breeze id feel a spider on me. Kind of sick and cruel but I gotta kill them when I see one. All bugs in general except for ladybugs. Lol I always found them cute even as a child.

i just realized the silk shirts and boxers i love so much are just spun out a caterpillar's bum...

That's a creepy ass picture wtf lol

Much misinformation in this thread and a lot of misguided fear.
All arachnids were not created equal. Some feed on your plants and some feed on the feeders of your plants.
Do as you will. In the end it won't matter. The bugs ALWAYS win in the end.

just found one in my veg room that crawled out when i was attacking gnats .... it's chillin in the kitchen now. I'll keep it alive. The fucker is big too but i can only hope that's from feeding on those fuckingfungus gnats
