Yeah I'm in california and this year is my first year growing so far I have seen aphids,spiders,ants,praying mantis,lacewings,lady bugs and preditor beetles. Years not over yet either. My solution is diatomaceous earth placed on the dirt around your plants and spraying the leafs with a 1 liter bottle sprayer mixed with a few drops of blue dawn dish soap and strained garlic powder. The soap will kill any soft bodied insects and wash away any eggs, the garlic helps improve your plants health and the smell repels bugs. The diatomaceous earth is basically microscopic glass that kills every insect within 48 hours of contact and can stay on the ground all grow season. Hope this helps any pest problems you may encounter! I know it saved my ass.

west coast cali and oregon... man... must be that elevation and just perfect weather.. i use protekt silica mixed with neem use 1 teaspoon silica plus 1 tablespoon neem oil per gal mixed very well. cant be beaten in my opinion once per week until week 2-3 of flower. DONT KILL THE SPIDERS they are your soldiers and friends. let them web up and eat the other bugs as they do no harm to your plants. i once when i was broke gathered up a box full of daddy long legs in my garage and put them on a 4 foot plant outside and they ate everything . they wil stay until you chop and ther rain wont kill them as they just go to the bottom of the leaves and ride it out. the neem kills everything lol and you gotta have silica in the grow. i add spiders after i quit the neem as too much is not good just here and there and it wont be a problem. im over here in the south where we get the storms lol
big trees normally a good indicator plants will be big too. 
only problem with ordering online.
I am very very lucky to be growing here. . . Can't wait to see what I can grow when I have some experience!
