Bio bizz light mix

[Kobayashi]

I’m using Biobizz light mix with Biobizz grow for my first grow, I want to keep it all organic if I can. I read somewhere that the light mix has a pH of 6.1-6.2 so you should water with pH 7.0-7.3 rather than 6.0-7.0 as stated almost everywhere else. Something about the compounds in the medium correcting the pH at the roots on its own. This would be great for me as my tap water is around pH 7.0-7.4 which means I wouldn’t need to use non organic pH down. Does anyone else have any input/experience/advice regarding this? Thanks.

If your growing in soil you need to keep your ph between 6.0 and 7.0 going in an coming out. Not just 6.0 or 7.0. You have about 10 points to work with. Not hard to do at all. Good luck.

PS. FFOF is supposed to be around 6.1or 6.2 also, the last two big sacks I bought were between 5.0 an 5.5ph, way to low for soil, so you can't go by what the bag or company says , that's why you better always double check the PH of the soil also, or else you will have either stunted or very slow growing seedlings.

All organic? Then I suppose you are growing outside?

[Kobayashi]

No, not outside, just using organic medium and nutrients. The reason I ask is that someone quoted an email from bio buzz saying they recommended watering with ph 7.0-7.3. I just wondered if anyone was doing this with good results. I suppose I should just test the run off and see what I’ve got.

This is what Ed says about pH - 'Most nutrients the plants use are soluble only in a limited range of acidity, from about 5.5 to about 6.5 in mineral soil and 5.6 to 6.4 in a hydroponic medium. Solubility also depends to some extent on the type of soil, planting mix, or hydroponic medium.' So I guess if your pH is above 6.5 then your nutrients are not being absorbed by your plants. Save some money by not using nutrients.

Having a look at the biobizz website they say you shouldn’t need to ph your water unless it is outside the normal 7.0 - 7.3 as their soil will automatically correct it. My run off stays at around 6.5 regardless of what I put in.

If you keep it between 6.0 - an 7.0 you will be fine, my plants seemed to really like it around 6.3- -6.5. Coming out, plenty of buffers in soil. Happy Growing
