Does anybody reuse soil after harvest?

Does anybody reuse soil after harvest? If so, How?

I’m sure @MrPeat reuses soil. I’ve done it by mixing in organic manure etc but my success has been limited


So I read that your suppose to pour boiling water over it to sterilize it then come back and add a lil more potting mix or perlite and peat moss maybe some compost as well. I’m just curious I know soil it’s that expensive but… yeah its not like I can just dig a whole in a my back yard


Yup…I reuse the same soil for years. You just start adding nutrients real fast is all. I do not add anything to the soil except nutrients. :+1::+1::+1:


So once you finish with the plant you dump all the soil in a container or something… what’s your process after you harvest your plant

I chop the plant. Take out the root ball and stalk. Plant seeds. Add nutrients about 1 week after breaking soil.

Rinse and repeat. That is all. :+1:

I have been doing this since May 2018.


Ok wow the dirt I have now is kind of stiff and I did just water it this morning but even then it still kind of stiffed up once I transplanted and it has grown a lot since germination… this is my first grow but if you say I can reuse it… I’ll reuse it… I still might just drop boiling water on it and let it drain before I put another seed in it

You can do what you want. You just need the roots gone. Personally I have never worried once I pull the root ball out. I just made things as I went along. I didn’t join a grow forum till Sept 23rd, 2019 and I started growing May 2018.

You can add soil if it gets low. I was using 5 gallon buckets with it only filled about 1/2 way. I was still able to grow over 7 foot monsters.

I now use fabric pots and the soil is still loose. :+1::+1::+1:


What fertilizers do you use and I’m assuming you don’t transplant either you just drop that one seed and call it a day

I don’t use fertiliser. I use Fox Farm products exclusively. Dirty Dozen with also adding Kelp Me, Kelp You and Wholly Mackerel. I use Fox Farms Ocean Forest soil.

And I do not transplant. They go into a 18 hour soak then transfer to damp toilet paper for 48 hours. Finally they go into 15 Gallon Fabric Pots. I also don’t move my lights either.:+1::+1::+1:

I’m a anomaly when it comes to growing indoors.


So whats your average time frame for plant and you must just grow FEMs only then… right?

I grow Landrace seeds. I have Autos and Photos. But yeah all are feminized except for the Landrace and Regular seeds.

From start to finish about 4 months per crop rotation. I will also grow 2 to 6 plants at a time in a 4x4 tent. :+1:


What’s landrace

A landrace strain, is either a full indica or a full sativa. Not a mix of the two, and they grow indigenous to their region . They are the founders of all hybrid strains we have today.

I use COM Bar Harbour organic potting soil. I reuse it 3x then throw it in the vegetable garden and till it in.

I mix in 1/4 cup worm caste per gallon and 1 Tbs mycos per gallon. After each use. Then I plant a seed or transplant a seedling.

I use Jack’s A and B, Epsom Salt, Fish Sh*@ and MPK in mid-flower. Sometimes I’ll add a molasses tee around week 4 or 5 in flower. Just depends…
