This is my 2nd soil grow, and my first organic. Thought I'd run this by you all before potting up. This is the mix they're going into for flowering

A 18 litre mix.

7 litres compost (peat free)
6 litres potting soil
3 litres vermiculite/perlite mix
1 litre bat guano (3-15-4)
1 litre worm castings (Plagron)
1 0z garden lime
Mycorrhizae fungi

All comments/suggestions welcome. Not too sure if that's the right amount of lime, apart from that I think it's good to go....
Thanks
 
look similar to mine .. tho my bat guano is 2-15-2%

is that "garden" lime .. Dolimit lime ? or sumthing similar that is easy and quick relies ..
I use Mearl here (Oceanic Lime) from Plagron ..

but look good .. dont think you will get problems with that ..

btw
I also add a few ts of Epsom salt .. mostly Bc. I have it and also just to make sure it have enough sulfur/Mg

p.s. :D

in my veg. mix I just use less Bat guano and instead add some blood/bone meal .. and also some Kelp/humid acid/vitamin B.
 
Mycro's in flowering? A waste of time if you ask me. I only inoculate seeds or a garden patch that's just been heavily tilled. If plants are outside and already in flower, other organisms will already be present in such large numbers they will out compete whatever you throw in. Inside they might have some limited success, but indoors organics don't do as good as synthetics. I love organics, but that's the truth. Outdoors organics all the way, indoors, synthetics usually have an edge.
 
I also hate guano. It might be "organic" in the strict since of the word, but it isn't organic in spirit. In other words, harvesting guano is not sustainable or friendly to the environmental. For these reasons and a few others, most organic growers don't use bat guano. It seems the only people who do are cannabis growers who don't really understand all the reasons for going organic other then it makes their bud taste better.

the reason it is unfriendly to the environment is that the bats use the poo smell to tell where their cave or home is. In Austin they have a bridge over water where bats live under. if they poo where they live it will just all be washed away. wouldnt that be the same as taking some? i use bat guano right now but plan on switching to a vegan source of P. it is just a thought.
 
Cheers guys, I only found that out yesterday, and had ordered the stuff already. I like a guilt free grow as well so it won't be on my shopping list again. At the risk of sounding like an old hippy; nature was kind enough to produce such an awesome plant...well, we know the rest.
 
I would replace half of the perlite you plan to use with ground oyster shells. I and many others have great results adding this to our mixes.
 
i also made a soil about 20 days ago. i used a local brand of potting soil that has 5 different composts blended together, perlite, EWC, some ancient forest compost, dolomite lime, guano(0-12-0), bone meal(6-9-0), epsom salt, and i added some all around veggie fert(2-7-4) the company is jobes. dont know how well it will do. gonna be transplanting some plants into it pretty soon. maybe next week. i will be watering with a basic tea with no nutes everyother water. might add some top dressing of it to some plants.I use it for 12/12 from seed but start the seeds in small cups before transplanting them to this soil. i need to start making another batch. and am looking for ways to improve it aswell.
 
What's the benefit of oyster shells? Calcium?

(Edit) I've found out it's used as a PH buffer in aquariums...same idea?

It's the change in odour that would confuse them I reckon...ever disturb a crusty cow pat/compost/cesspit?...phew!:spew:

It is a stable, long lasting source of Calcium and provides the similar aeration/water holding capacities as perlite.

I actually don't use any perlite in my mixes, just oyster shells.

I get mine from Tractor Supply co.

Really cheap, marketed as chicken feed supplements.
 
Thanks everyone! Oyster shells for me then. A source of calcium, does perlite's job, and a sack of chicken feed on my shoulder won't raise any eyebrows as I walk through the one horse (house? lol) town I live in...
