Looking awesome I have a similar setup I am working on hopefully it turns out this nice.
Aphids have gone down alot but still an issue, I am no longer angry at the lady bugs for hanging out in the corner, they had their orgy and are back to eating aphids. I saw something strange on my hydro tub so I took a look and found a bunch of lady bug eggs, took a look at the side and found more eggs. So in 4-10 days should have some really hungry larvae on my hands. Should be the final days of the aphids.
Nature, got to love it... And yes Neem oil is awesome. I think of it as salad dressing for my growing plants.
Good to hear them ladybugs are smashing those aphids, lazi!This here thread coupled with something I witnessed yesterday in my own backyard--hypoaspis predatory mites going to town on fungas gnat larvae--has truly inspired me to try predatory mites against my broad mites this season. Something's really gotta give!
