Need advice - soil mix

[firetech89]

High,

Getting ready to make a batch of soil. Does this look like correct ratios, should anything be added or removed?

That looks good friend, however, it seems like a lot of lime to me. Pro mix # 4 is what? Do you mean Sunshine mix #4? Mix it up and keep us posted on the results. It would be interesting to see how it works for you.

Thanks Creeper, yes it is sunshine #4 my bad. What would be the negative consequences of that much lime? I did mix it up yesterday, however don't plan on using it till mid/end of May. If it is too much lime, anything I can do to balance it?

All you can do is wait, friend. Have you ever tried this recipe before now?

I was going to ask the same.. Sunshine#4 is 5.5-5.8 after adding everything the pH will drop. Fresh mixed it will be hot. Wait at least 10 days. Make a slurry and test the pH. Add lime if needed to get back to 5.5-6.
Lime is used as a PH buffer.. It keeps the PH stable..

I have not used this exactly, I have used this one before with great results, the only difference is the added azomite and oyster shell.

The type of water you plan on using will play a big role in how much lime to use. What kind of water are you using?

6.2-6.8 would be better for organic soil.

RO comes out to <10 ppm

Sunshine bag will be 5.5-6. All soilless bags are in this range. It's up to you where you want the end base mix pH to be. Microbes prefer a neutral ph. I feed at a ph of 6.4 using any bagged soliless. There all at 5.5 - 6 right out of the bag.

You will need more lime with R O water. I wouldn't worry, just test the runoff pH and you should be fine.
