Well poop...thought I had my last clone doing better (if it survives it will be yet another testament to the hardiness of this unknown bagseed strain lol) and when I went to inspect it this morning I noticed that now it has thrips. I'm 99% sure they are anyway...pics are on the last page of my journal (page 16 for future reference) for reference.
Anyway I went to the hydro store and was told that the neem oil itself won't kill them and that I need to go a dual-action route with neem AND Azamax to hit them in all parts of their life cycle. Makes sense...I was short cash although I could have purchased the Neem oil; I just wanted to come back home and do some more reading first and see if I had some alternatives.
Right now I don't see too many, I think I only saw about four or five different ones over three plugs (tossed one plug, have two left, probably tossing one of those too) and killed one with my finger. So they're not a major problem yet but I do not want to let it get that far and I'm quite worried about them spreading to my flower cabinet in the other room...if they haven't already, I can't check for a few more hours.
I found this thread on diatomaceous earth and thrips and it sounded promising. Has anyone else used just D.E. with success on thrips?
Aside from being able to treat the problem it would also allow me to make a protective ring around the flower cabinet to help reduce the chances of them spreading there...if they haven't yet. I have used D.E. before in herbal gardens and to fight fleas, quite effective stuff ime.
As that thread leaves off they are discussing what D.E. does to soil pH and consensus was it goes up...makes sense given what it's made of.
Can I coat the exterior of the plug my clone is in with D.E., like when you roll food in a flour mix before frying?
If they are in my flower cabinet can I use it as a foliar spray if they're in the leaves since I'm three weeks in to flower and my buds are just starting to get some body to them? I like the idea of wrapping the base of the stem with D.E. coated gauze.
