re-using soil worth it?

thank you for your answers all ! When I asked the question I also thought about the soil as a waste and what to do with it. Going to the recycling park brings costs and I think, according to the answers I got, I won't take the risk to have bad yield and just buy new soil.... I got the idea after flushing thoroughly to use the old soil for my apple tree's and japanese maple tree's in my garden. I still have to transplant them and my garden soil consists mostly of sand soil... Best to mix it with this peat moss.. :-) I wish you all succes with your grows and harvests !

If it helps I re-use mine in my veg garden where the veg are not too particular about how the nutrients are stacked. Also I fill my oudoor weed grow holes with old soil because the rain and reconnect to momma earth balances it back out in no time and its still a great "blank" medium. Waste not want not! Stick Buds!

Das Problem liegt meiner Meinung nach in der Struktur der wiederverwendeten Erde 🤔 Ich habe festgestellt, dass ich bei hohen Anteilen Wiederverwendeter Erde eine schlechtere durchwurzelung der Töpfe hatte. Der Ballen zerfiel jedes Mal sehr leicht und die Erde war pulverartig 🤔😄

GreenOrganicGermany, very interesting that you use 70% fresh... According to Biobizz, mixing the old with 30% fresh soil and worm hummus is more than enough.

hi mooncat, no repotting or transplanting. Just seed in soil. So the plagron super mix isn't suited for seedlings. Just like I thought. What about the plain worm casting/hummus mix? That one should be much lighter.... Will it give the same yield and fast growth??

Ich nutze ebenfalls wiederverwendete Erde. Vom Grundprinzip behandelt ich sie genau wie du, ich nutze Zum Aufbereiten Wurmhumus dazu etwas Garten und Pilzkompost. Das ganze lasse ich etwa 6 Monate ruhen. Zur Verwendung dann Perlite und Kokosfasern hinzugeben. Allerdings habe ich bei der erneuten Verwendung die Erfahrung gemacht, dass es den Ertrag negativ beeinflusst, wenn man ausschließlich wiederverwendete Erde nutzt. Die besten Erfahrungen und so mache ich es seit einigen Jahren ist eine Mischung aus 70% frischer und 30% wiederverwendeter Erde. Da sind keinerlei Unterschiede festzustellen. Also meinerseits😁👌

Repot/transplant? I mean ,,recharging,, your soil takes like 2 weeks+ If you dont want to wait just mix your old light mix with the Plagron in a 3/1 Ratio wait till your plants are big enough and go for the opposite for the final soil.

Plagron Super mix is another product which already contains worm hummus but comes also with elements: Feather meal, bone meal, Guano Peru, nature phosphate, maerl, bentonite, basalt, seeweed meal, lava meal. Organic NPK-fertiliser solution (1-2-0). 1,2% Total nitrogen (N) of which 1,2% organic nitrogen, 1,6% water-soluble phosphorus pentoxide (P2O5), 0,35% water-soluble potassium oxide (K2O). Those extra's are actually things you need to make super soil.... Mixing my Biobizz Light mix with this product could be too much I guess??? I use autoflowers and could be that the seedlings will die off quickly... Should I stick to only plain worm hummus?
