Subcool Supersoil UK version a few questions.

[Duggy]

Dazed.. I have the plagron bat guano 3-15-4. I think using it alongside other P sources at 1/4 dose may be better which reduces concentration and brings more diversity of ingredients. I havent seen a need to add epsom as there seems to be sufficient Mg in the lime and a little in the silica clay which maintains a higher % of Calcium which is desired...

Blue, if we can get this down between us (and when I can, I will totally be the guinea pig lol) how cool would it be to have a solid go-to mix for us UK'ers, with easily accessible amendments, that works under LED!

Phew, so, all that being said, could we experiment?! I have approximately 50ltrs of the soil mix I listed above, should we ditch that and start again or would it be worth amending it with what (the general consensus) is missing?

Dazed - I'm certainly interested in watching how it goes - i think the list of ingredients would need to be vastly trimmed down in order for me to give it a go (i'm self confessed lazy), but if it works well i cound be seriously tempted.

My water PH from the tap is a dissapointing 7.8 PH - which i think means ... TLO or Organic or whatever, i'm gonna need to get my PH somewhere closer to 7 (or less) in order for anything to effectively grow. That's certainly the impression i got from reading the canna BIO section after considering BioTerraPlus soil and their Bio range of A&B, Rhizo and Boost.

The thought of just adding water from the tap and getting glorious results is the dream!

well if you got 50 Litres of soil Id personally get a base similar to the EWC,Organic soil(your soil is fine id imagine too),perlite,and some coco..then you also have several amendments on hand..

and honestly I dont know how much 300g is as far as compared to a cup..various things are processed more than others and the weight will be various through the measuring.so if you could get that worked out for me that'd be great LOL! but you can experiment but you'll need a base more than plain soil for texture and leaching of products n so forth.but you can essentially add more body(Base) to the soil and work the amounts to cups if ya can and add some more of some and less of others and the mix should do fine.gypsum is nice and the pellet lime is good too.those three things ,should help you avoid any PH issues.

I myself have a PH swing seasonally since I run my tap (well water) from an aquifer and seasonally it changes..especially if you brew simple EWC teas with an ever so small pinch of guano to boot..no more PH issues..LOL! then even with high PH in your water less than 8? noo problem..mine was right about the same actually.

but those are you two choices imho bro.

Excellent brother! Well, I think its' best to start a fresh batch, I'm not running anything for a while anyway, my friend can decide if he wants to amend the current mix and see how that goes or wait for a new batch to cook. Going to keep it super simple again, but this time with the gypsum, oyster shells and silica and a half cup more of the egg shells. I'll reduce the amounts of the 1-10-1 guano a little too. I'll work out the amounts and post them here before I do it, just to get the second opinion from you guys before I mix.

Thanks for the help

 

[Eyes on Fire]

Sounds like a winner bro!

Hey all! So just waiting for the last few bits to come for the amended soil mix. Here is the proposed mix with addition of RAW Silica, crushed oyster shells, Gypsum and Humic Acid.

I halved the amount of Hoof and Horn and Bat Guano, added some more coir and perlite.

Whats everyone think?


50ltrs Allmix
20ltrs Coco Coir
20ltrs Perlite
4lbs/2kg Worm Castings
4lbs/2kg Leaf Mold
10oz/300g Bone Meal 3.5-17-0
5oz/150g Bat Guano 1-10-1
5oz/150g Hoof and Horn 13-0-0
10oz/300g Seaweed Meal
2 tablespoons Volcanic Rock Dust
1 tablespoon Mycorrhizae
1.5 tbs Powdered Dolomite Lime
1/2 cup Egg shells
1.5 tbs Epsom Salts
2 cups Gypsum
2 cups Oyster shell
1 tablespoon Humic Acid
75 ml Silica(?)

Hi Dazed
That list is very impressive you really know your stuff now dude.
Will you have to feed your plant through its cycle?
Or are you trying to create a medium that does not need any kind of feeding.
Now thats something i would like to get into, did you see that brand of soil that claims your plant will not need to be fed.
I think Eyes on fire made a post on it somewhere.

Hey mate, this is something that hopefully won't need anything but rainwater and some molasses. I think adding molasses during flower really helps, and maybe once in veg.

I read an awesome piece on molasses a few days ago http://forums.strainhunters.com/topic/7879-3-little-birds-molasses-manual/ , lots of great info. I didn't see the soil Eyes posted, will try to find it. This is basically sub cools mix but with UK amendments, if it works, I'll post links up here to where you can buy the products. Going to use this thread for the grow journal when it happens.

Going to 3 tier the pots so; bottom 1/3rd soil mix, middle 1/3rd Allmix, top 1/3rd Light mix. Or something like that lol.

Compared to mixes by the likes of @Eyes on Fire , @DubV , @Duggy , @A4 etc, this is really basic, but that's what I want - and we all know the variety of products in the UK is very small compared to the US, with this mix, the products are easily accessible here.

Going to get mixing tomorrow hopefully!

EDIT: just thought I'd add that the molasses is to provide sugars and potash,

Anyone else any opinions before I get mixing?

 

[DubV]

My brother Dazed So just looking at your mix, I would make a few adjustments. First off, your aeration is too high. This will cause cal/mag issues. Your aeration level should not exceed 30% but should be as close as possible. This number is always determinant of you start base mix like Allmix. By adding coco and perlite, the mix will be way to aerated. Also remove the lime. No need for it with the oyster and gypsum Also if it were me, I would up the volcanic rock dust up to 1/2 a cup minimum. Working with what you have and can get, this should be a pretty rockin mix but make sure to let is cook at least 2-4 weeks before using. Hope that helps and much love my brother
