Check the 4-4-4 mix you plan on using, any amendment mix worth its salt will have kelp meal in it. Find another mix if it doesn't IMO.Well I’m not so lucky. Canada eh!
Bail peat $35
Perlite $40
Humis $10 32 litre bag
Gaia green 2 kg tubs Are $25-$30 ea
Gaia 444 10 kg $50.
I’m thinking the cheapest way is a cup and a half of 444 with 4 cups rock dust per cu ft. Maybe a cup of kelp.
A non-cheap part of Canada I guess. Here in Ottawa Valley area in Eastern Ontario, farm supply seed & feed outlets are your friend. Canadian Tire often has sales on the Pro-mix bales, especially this time of year. Redflagdeals is a good site for watching. Ritches seed & feed sells those HUGE bags of perlite for about $26 with all taxes in. Alfalfa pellets are even cheaper by the 50 pound seed bag. I don't use Gaia green or anything else that is manufactured/processed and comes in plastic tubs, so I can't comment on that one. I just don't see the need with my grow style. No idea what "humis" is, or why I would need it either. I'm a very simple grower. LolWell I’m not so lucky. Canada eh!

The extra price is because it takes a very special super soil to properly circulate in a hydro system. Lol /sSome dickhead at the hydro store wanted to sell me a homemade “super soil” mix for $15 a pound.
Ya thanks. That’s US$ here in Canada it’s a little more then a dollar a litre. So that 10g bag here would be about $50.Heres a place that sells no-till living soil in the U.S. Thought it might give you some idea
1.5cuft for $27.99
1 yd for $375
