They only get water through the Blumats.
I use mostly rain water, but occasionally, if it doesn’t rain for a while I will have to give them tap water but add some sodium thiosulfate to neutralize the Chloramine and Chlorine in my water (I use a “water conditioner” product from my local pet store which is designed to be used in aquariums with tropical fish which are a lot more sensitive to those chemicals than plants).
I haven’t PH’d any water in probably 4 years.
In the past that was because I was using rain water, but on top of that factor that’s actually one of the benefits of growing in Living Soil. Your plants will communicate with the microbial life in the soil to adjust the PH around its root zone to exactly the levels that the plant wants (which will change during different times in your grow and may even be different in different parts of the root zone to allow it to absorb specific nutrients from the soil better).
Nature is pretty freakin cool and smart like that. She’s been successfully growing plants for Billions of years with no person there PH’ing the rain, rivers, streams, oceans, or ground water supplies.
As far as what I feed them, my initial soil mix was approximately:
-1/3 recycled M3 (with the root balls of the previous crop’s plants still in it)
-1/3 Promix (basically Peat Moss, some perlite for aeration, and some mycorrhizae)
-1/3 locally sourced Compost (some from a Compost pile I made myself and the rest from already finished Compost I found locally for a great price)
Then I added Red Wriggler worms, some local Composting Worms (most likely Night crawlers) that I pulled out of my pile, and of course the 13 species Cover Crop (which I eventually crimped and mulched over so it would die and be broken down by the worms and bacteria so that the plants can use the nutrients sequestered from those plants).
I also gave them a Top Dressing at the Flip (which went onto the soil and got mulched over along with the Cover Crop) which consisted of:
-bone meal
-alfalfa meal
-Kelp meal
-greensand
-Azomite
-Glacial Rock Dust
-Soft Rock Phosphate
This was to help make sure they had everything they needed to power through their Stretch/Transition period
Finally I added a “Bulk” Top Dressing at the end of Week 2 after the Flip of:
-Bone Meal
-Kelp Meal
-Alfalfa Meal
-Kelp Meal
-Langbeinite
-Soft Rock Phosphate
-Greensand
-Azomite
-Glacial Rock Dust
-Basalt
This will give them everything they need to thrive and “bulk up/build their flowers” till Harvest.
After I harvest everything I will do another “Veg specific” Top Dress for the next Crop and repeat the process.
It sounds quite complicated but it’s really not. Plus I mix up large batches of Top Dressings for each phase and then only use about 1-2 cups per plant for each dosage/round. So it’s not too crazy time consuming either.
And this is just one way of doing it as well. A couple of my Living Soil buddies use what they call “Avocado Tech” which is basically hollowing out two halves of an Avocado and then blending the “meat“ with amendments in a food processor, then scooping it back into the Avocado shells and putting the shells down onto the soil under each of their plants. The worms then come up and eat the contents and as they poop and crawl back down into the soil and poop those nutrients become available to the microbes Who break the down further and plants to use.
So several ways to do it.
I also brew Actively Aerated Compost Teas (AACT’s) for them every week to two weeks to keep the biology in the soil at optimal levels and to inoculate the leaf surfaces and other above ground surfaces with a protective layer of biology (to help stave off possible pests/infestation as well as pathogens (molds, blights, etc...).
Hope this wasn’t too much information at once.
