710 ml bottle (off the top of my head)
I tried lights on, no real issues.
The only burn was on young seedlings and a very sensitive cut.
Lights out is the best bet, tho.
I had a recent thrip infestation heres my opinion
If you didnt bring them in from dirty cuttings or a medium then they probably are coming through you intake ! I had to screen my intake well and the problem went away instantly. with that said yes spinosad is the best option to take them down but u need to find where theyre coming from but id also recc. a bomb for follow up to get any remaining. Also get some blue sticky traps to be able to tell if a population is amounting.
there one of the easier pests but they do cause damage and are vectors of other nasty shit
ewwwwwww bugs
oh yes ! one more thing people tend to fail to mention.
if youve had these guys for a good time they have definitely dropped some nice eggs for you in your medium waiting to hatch later on !
you need to not only attack them up above but also need to hit them with something as a root drench to get the future gen.
good luck
Spraying at night cycle? Have you tried lights on or full sun? Any wiff of burn?
I kept meaning to come back to clove oil, never got past "a few drops" in a kitchen sink spray. Drowned out in the other noise.
Please let me know how that spinosad works! Ive been hearing/reading very good things about it.
Zero Tolerance has been a bust for 'em for anyone considering it. Next day after a thorough drenching, there are live thrips on the leaves. Picking up some of that Monterey Garden Spinosad. Hate these fuckers.
