I don't know abou
T the sand,I can only vouch for stuff I've used.i mentioned the bio premix as it has everything in it,makes it a lot easier than buying bags of 10-15 different products to amend the hot mix.ive used this pre mix numerous times,with no deficiency.ewc are a must,and beetle frass is excellent.I also use a cheap box of fish blood and bone meal.once you've mixed in some of this to a good mix mate your laughing pal.after harvest,I pull out big roots,break it up,and throw it back in the soil bins for another round.i just throw in some frass and worm shit every few runs to beef the microbes and N levels bk up ready.honestly pal,that
bio bizz stinks of hoss shit but it works.adds all those extra goodies like rock dust and crab shell and lots of other goodies.if you add neem cake,it has lots of N extra for growth,but it will keep all those nasty bugs and critters at bay too. Good luck pal,even though ,you can see my plants already,been growing with these few products for the last 18 months or so.had the best bud I've ever grown from it,and the more I get it dialled in,the bigger and stronger my girls get. When you have the stuff ,pm me and ill help you mix it all to the same amouts.you'll need a tarp,and a couple of bins with lids to store it.
