Sorry for the dumb question, but what is "Roots soil or equivalent high quality supped up grow soil"?

I'm guessing that's just a brand name of soil available wherever Subcool lives. Most of the stuff (brands) he uses isn't available here (or not where I live).


Glad you bumped this along though. I'd forgotten this thread existed.

have a qestion for ya mate. when changing to bud after dark, does going into 12 12 with the metal halide or whatever u use to veg, make your plants any different from doing it under the hps . have found that everyone does the change under the hps so i have no experience with that . like can you go 12 12 with your veg lamp and then into bud after the two weeks or do you have to go straight to hps for good yeild. i would like to know as i have no access to clones, am starting from seed and dont like the idea of having a mother plant always sitting around and want to only put females in my setup . Have trouble with genetics so have to sort peoples fucking shitty crosses out my big mix of seed

8 Bags Roots soil or equivalent high quality supped up grow soil

25 pounds Pure Worm Castings

½ cup Azomite trace minerals

2/3 Cup Sweet Lime IE Dolomite

1 Kilo Bone meal / IE 5 Pounds

1 Kilo Blood meal ( I use a bit more bone than Blood in this recipe)

1 Kilo Bat Guano bloom formula preferably Fruit bats

3/4 cup Epson Salts

The Perlite and Coco I happen to have and it will make a better mix but it is not necessary.



Ok gentlemen, I may have worked out a way to make this great mix in aus.. i do apologise if someone had already stated this..


Bone Meal - phosphorus source

Blood Meal - nitrogen source

Epsom salts - magnesium source

lime -calcium source & pH buffering

Bat Guano bloom formula - nitrogen & trace elements


I havent worked out what worm castings do and at the moment can't find a replacement for the base..


any help or sugestions would be great...


Subcool - thank you for sharing your recipe.

I have recently mixed up a batch of this soil using the best replacements I could find. As a disclaimer I haven't used any of it yet so I hope its not too hot but I'll know in a couple weeks



I used Niks Mix as a base. Has the same Coco base as roots with similar additives. Buy it or find closest distributor from Niks Mix


Worm Castings: Cheapest source I could find Scrap Ltd.

Apparently highest quality fairly expensive though Wormtec


Blood and Bone meal is available from Bunnings and most gardening centres. Try get a pure blood and bone meal not one with added potash etc


Dolomite Lime is the same as above


Fulvic and Humic acid powder at NTS


The only source I could find for powdered Guano is also NTS


I added Kelp Meal, as its in Roots but not Niks mix. It's available from a couple sources, but varies in price greatly Wormtec is expensive but sells smaller amounts

NTS about $70 for 25kg

Urban Gardener Shop is more expensive, but has a range of other products, like worm castings diatomaceous earth hydro equipment etc


Azomite can be found at Living Apartment but from what I gather you can use a volcanic rock dust product such as at Urban gardener shop volcanic rock dust


Any questions just ask
