It's not a soil mixture I'd ever consider attempting, but I could make a wild ass guess. I'd start with the soil being the largest part of the mixture, say 80%. Then I'd guess at the cow manure being 10%. That leaves the other two to complete the mixture. I've never seen blood meal or bone meal, so I can only guess the volume. Together, the two are basically providing N, P, K and Ca. So, it's a question of how much of those nutrients you need to add to the Promix. Because those nutrients can easily be added at any time, I'd start with lesser amounts to avoid nutrient excess.
I'd have to go back and read the directions, but I'm pretty sure that the blood meal States a teaspoon or 1 tbsp , per liter of soil. Because the pro-mix already has nutrients and the cow manure, I'll probably cut the ratio of Blood meal to a half of its ratio.
If you knew that, why did you ask? Of course, read the directions. It's better than me wasting my time trying to help.
Bone meal isn't available right away it needs to break down first same with blood meal but the blood breaks down faster so add those at the start mixed in. The bags will have basic instructions for how much to add to your mix but remember you can always add more nutes if needed as a top dress but taking them away is much harder. It seems like your trying for organic? If so and you have yet to buy the promix they do have one that is organic called "promix premium organic vegtable and herb mix" it was the same price as the one you have shown here. Very close in composition but all organic. I think you will want to add some perlite, lava rock or pumice for better drainage. Also you will want to find a source for potassium as your plants will want much more of that towards flowering.
Thanks, I was thinking using the bone meal for some top dressing drawing flowering.
Ignore my organic comments it doesn't matter what promix you start in if those are your nutes. I also can't really help with those. I am not very experienced with synthetic stuff. I have heard its not ideal to mix organics with synthetics as it creates a lot of variables but hopefully someone who knows more will come along. Happy growing!
It's legit, I am messing around with craft next run in my super soil
If you are using synthetic nutrients then there is no reason to add bone meal.
Personally, I use Seabird Guano (0-11-0). Animals that are fed GMO grain and get pumped full of antibiotics can still have their bones used for 'organic' bonemeal. Sure, there is no calcium in SBG, but I also use crab meal which contains calcium, magnesium, nitrogen and is made of chitin... chitin triggers an immune response in plans because it is what insects are made from.
I second that.
Now would be a good time for bloom boosters, IF your gonna use them. You can use a synthetic version like Flower Power or an organic version such as banana water and bone meal/seabird guano tea.
It’s is all I use. I amend when I flip to flower and when I chop down plants. It gives my soil 2 weeks to break down the craft blend then new clones go in and 4 weeks later I’m back flipping to flower. I’ve ran the same soil for six or seven cycles. When the stuff in my small tent finishes up I am going to do a cycle with 3.0 recipe in sip pots. I will amend the soil when I start and only feed it water the entire grow and with using the sip pot I will only be dumping it down into the reservoir. I just want to show people this does not have to be complicated.
