Pro Mix PH

[sharks]

I am using a pro mix as a grow medium. Please advise if this is a soil or a soiless medium. Also what PH should this medium be? I appreciate al help.

Pro Mix is all I've ever used. It is considered a "soiless" mix as it contains no soil (as in black topsoil) Fresh out of the bale it's Ph is low until it's moistened and the limestone can react with the peat to counteract it's acidity. You have to keep it flushed with each watering to the point of heavy runoff to keep the Ph at it's proper level. I don't know what the PH is after wetting but it's good as I've had no problems as long as you keep flushing it.

Frmrboi, Thanks.

What ph is the water you are watering with?

Frmrboi, Thanks.

I don't know, I don't have a tester.
I use rainwater (Vancouver, we get LOTS) which I'm told is 7.0.

Your water, after you add nutes, should be at a PH of 6.5. I would suggest using that Pro-Mix straight out of the bag with no additions on your part.

Hey Farmboi, I'm getting ready to use pro mix - waht do you mean by keeping it flushed. Do you flush with water between feedings? Or you just mean that you let the nuted water run through?

Thanks!

i use promix as well. what there refering to is flushing out the salts that build up from nuting.


water enough so that each time a little water come out of the holes at the botem

no i do a big dose once per week

 

[overmyhead]

no i do a big dose once per week

Thanks. What ppm's is it when you feed? The food that is.

 

[Ghost420]

last feeding i had a ppm of 1250 stepping it up this week

In my experience, promix will slowly drift your ph up. I've had to use Ph down to counteract this.
