sir_isOanswered grow question 4 years ago Uh, I dunno.
But I *vehemently* disagree with gmslave about using dawn soap.
It contains a bunch of CRAP.
Methylisothiazolinone (one of it's ingredients) is allergenic and cytotoxic.
The American Contact Dermatitis Society named Methylisothiazolinone “allergen of the year” in 2013.
Other things in dawn soap includes sd alcohol, sodium chloride, sodium laureth sulfate and magnesium chloride.
None of that shit you want on your plants.
