Hello. Nice looking plant, by the way.
I think all spiders help somehow (except spider mites) but if the have to be moved don't hurt them.
I would to talk about the main issue the aphids. The best way I have found to deal with them fast is squish them with your fingers. Yea- Yuck right, but here's why -
The aphids have a mouth part that is like a cork screw. It's hard to pull straight out. If you get in there and break that cork screw the aphid can't feed even if the aphid lives. You can devastate a colony just by squishing them with your fingers. Then just a light spray of water to wash away the crushed bodies and juices. But I don't mind smoking the dried bodies of aphids if all they have eaten is cannabis. Second choice - A strong spray of water can dislodge them and break their moth parts but the young ones live and might climb back on your plant. You can use a spray bottle set to jet spray to knock them off. Please look into getting some Lady bugs or some Lace wings from the garden center to help. You have to order them then go pick them up. If you have aphids now it will be a problem all summer long. In Canada the government has banned Neem oil because it contains heavy metals so don't get on the part of the plant you smoke or eat. Good Luck. Chuck.
