^^ Great post, Coba.

I have a quick question about re-amending recycled soil.
I have 2 5gallon buckets mostly full (~9 gallons) of used ocean forest. Half of it was straight out of the bag used for about 1.5-2 months and plants were healthy when chopped (males). The other half was used for a full flower run and I think I added a little coco and perlite, extra ewc and maybe some high p guano to that one not sure it has been quite a while.
Anyway I usually just buy a 1.5cu ft bag of FFOF for $20 and just toss it into outdoor beds/planters once I use it. A bag lasts me 1-2 runs depending on number of plants and size of grow bags (micro grow).
I could keep getting a $20 bag of fresh FFOF every 1-2 grows but seems about half the time lately they have been coming amended with root aphids for free.
I can get a bag of amendments for a 1.5 cu ft bag of soil for $18.60 shipped and the bag includes:
"Super Soil Amendment for 1 Large Bag (1.5 cf) of Soil Mix
Approximately 3 lbs of organic fertilizer soil amendment, with the following ingredients:
10 oz Bat Guano (1-12-1)
10 oz Bone Meal (1-15-0)
10 oz Blood Meal (13-0-0)
8 oz Potassium Sulphate - Potash (0-0-50)
1 cup Kelp Meal
2 tbsp Epsom Salt – Magnesium Sulphate
2 tbsp Azomite
2 tbsp Endo Mycorrhizal Fungi (134 spores/g)
2 tbsp Dolomite Lime
2 tsp Granulated Humic Acid
(add to the mix ~6lbs EWC mentioned below, which I have about that much EWC left hanging around)
This mix should be combined with 1 large bag (1.5 cf) of high quality organic potting soil mix and approximately 6 lbs of organic earthworm castings to create a long lasting “super soil” that will take your vegetables, flowers or herbs through the vegetative and blooming stages. Best if pre-mixed with water at least one month ahead of planting to allow the fungi to become established in the soil and the fertilizers to begin to break down. Make sure to keep moist until planting. Note this mix is too hot for seedlings, as it will burn the roots. You can transplant seedlings after a good root system has already been developed, or you may place the amended super soil in the bottom of the planter, and place your seedling in a layer of un-amended soil at the top."
Do you guys think this amendment mix would do me well if I mix it with the used FFOF and water with a compost tea or lacto bacillus and keep moist/turned for about 6-8 weeks until I need it for the next batch? It is roughly the cost of a new bag of FFOF which may or may not come with pests included so I am thinking I might like the option of trying a recycled amended soil mix, which I have been wanting to do for some time now anyway.
I guess I am just looking for a go ahead or not to purchase the amendment mix and start composting it. But if its not a good mix I might pass, it would cost me a lot more to buy amendments separately, though I would get more of each but I would use so little of each it might not be cost effective in my situation to build my own amendment mix.
Just dont want to buy it if its got bad ratios of amendments or anything that stands out as bad to you guys more experienced in re-amending soils.
So how would I fix these issues? Perhaps filling the whole container with the amended soil was an issue and I should have cut it with half LC's Mix #1?
I like fish meal and fish bone meal over bone and blood meal. The differences is that you may get a higher mercury count (and possibly low levels of radiation if sourced from the Pacific, thanks Fukushima) and a few other potentialities, but if you've ever looked into industrial slaughterhouses you'd never buy blood and bone meal again. I'd much rather substitute the fish by product for the cattle byproduct. Cattle are injected with hormones, vaccines, other unknown chemicals, they are neglected and stand in puddles of their own shit and blood their entire lives in cages with only 2" of moving space for them. I will never support that industry and besides, I truly believe because of the aforementioned that fish byproducts are of much higher quality than slaughterhouse byproducts.
As for the Karanja, it is not a substitute for blood and bone meal, but is the exact same thing as neem meal. I'd not skip on neem or karanja, ever. Both are amazing pest repellants as they contain the compound azadirachtin.
Insofar as azomite, use 1-3 cups per/cf. If using your own crab shell definitely wash it of all salts before adding it to the soil.
Also, don't add myco to your soil mix, it's entirely pointless and will do nothing for your soil. Only use myco when transplanting. You definitely could entirely skip on the guano, I don't know many pros that use it. Epsom salts goes the same way.
Make sure you humus source is of high quality as is your EWC. 1/3 compost/EWC, 1/3 aeration, 1/3 humus (leaf mold, alaskan humus, peat, etc).
If using Bone meal, Blood meal, azomite, powdered crab shells, kelp, and karanja meal i'd mix it somewhere around:
Per c/f of soil mix
Bone Meal 1/2 cup
Blood Meal 1/2 cup
Karanja Meal 1 cup
Azomite 2-3 cups
Crab shell 2-3 cups
Kelp Meal 1 cup
Hope this helps....
A simple mix like this will without a doubt get you a high quality product. My current mix has 42 ingredients, some are redundant, but biodiversity is crucial in a living mix. For example, neem and karanja are two different amendments that serve the same purpose, I do 50/50 on those two. 2 amendments, 1 purpose; because I can!
Ya, unfortunately Im thinking Im not going to be buying a bunch of different amendments like I would want to for such a small amount of soil (I use so little). One day when I am running something larger and it is worth the cost to buy a bunch of different amendments in bulk and create a very diverse mix.
I only use myco at transplant like you said. I dont brew as much as I should or would like to but I also try to use fungi and bacteria heavy compost teas.
For the crab shell salts issue, should I have rinsed before grinding into powder? If I tried to rinse now there wouldnt be much left the vast majority of it is powdered and some tiny pieces mixed throughout too. I ended up with 1 cup from the 1-2 crab shells I used. Might not use it now you say this though.
Thanks for the help.
Hmm, I am not much of a chemist, but I am sure there is a way to rinse away that powdered crab shell of salts. I'd probably just buy some if you are feeling a bit overburdened by it. The best website on the net for high quality and by the pound amendments is without a doubt http://www.kisorganics.com . Run by a highly esteemed grower, Kis Organics has the best of organic ingredients and you can choose to buy everything by the lb. Another great face value about KIS is that all the prices you see include shipping.
Here is a mix in tempted to use. Why? Because its what I have on hand. If some one had some input on my concocted mix please share.
1 part black gold potting mix
1 part Fox farm original planting mix
1 part Fox farm ocean forest
1 part large chunky perlite
I also could do 1 part light warrior
I am thinking about cooking for 30 days using a compost tea for moistening. Also putting a seed starting heat matt on the under part of my plastic concrete mixing bin that the soil will sat in for that time period.
Was only going to use a compost tea once a week(the mix is sold by KIS and I have purchased there upgraded compost tea brewer).
My watering method is a vague area for me and am considering 2.5ml/gal Dutch master root zone conditioner along with Flora nova bloom at 1/2 tsp per gal. This mix would be brought down to 5.6-5.8 pH from my municipals 7.6 pH tap water. I would use this mix from veg through flower.
I'm sure there are a lot of opinions and am open to all. The response to this I am hoping will guide me through to a good harvest.
My lights are HGl's SOL series and I am using air pots.
