I would appreciate some help about the correct way to flush soil using sledgehammer.
I follow the Foxfarm nutrient chart that recommends flushing with Sledgehammer at least 3 times per grow.
I have read many posts about how much PHd water you need to flush out the sledgehammer.
I’ve read anywhere from 1 gallon 3x the pot size.
Obviously no one wants to use more water than necessary.
I contacted Foxfarm multiple times for their official answer.
And now I’m even more confused.
They insist no rinsing off of sledgehammer is necessary. (See emails).
That contradicts everything I’ve ever read.
Anyone experienced using sledgehammer that could set things straight?
