I would put diatomaceous around the entire exterior of the building every 3-6 months. Then spray an average bayer or home defense bug spray on the exterior. Running sterile would make it very hard for aphids to live. Hard for anything to live in an h2o2 environment. I add it every 3 days. Also, bayer "imid" or imidichloride would keep aphids back for good. Can only use it in veg it has a lengthy half life. That shit works wonders. As for fusariam, im sorry to hear thats the issue. Keep it clean, thats for sure! Grow looks amazing otherwise very well done!
