I started growing a plant in FFHF, the plant only made it about 2 weeks and got about an inch tall but didn’t live. Can I reuse the soil for my next grow?
Thanks!
You can, but if you didn’t ph your water, be extra diligent to do so. May also have to feed sooner.

Agree with @Covertgrower. It will take diligence and extra work. I would ensure it is mixed well and test both pH and PPM. Correct for pH (~6.3 - 6.6) and then correct for nutes (~900) and proceed from there.

Thanks all, the plant that was in the soil barely grew, so I don’t think much of anything nutrient wise was used from the soil. It was basically a sprout and mainly was hydrated by the humidity dome on top using distilled water.

I reuse the soil but not for cannabis.
I will use it to grow other garden veggies or herbs.
Mostly just as a starter mix for tomatoes and peppers.

I started growing with 6 cubic feet of FFOF from May 2018 to present. Many big grows.

Are you reusing the soil alone? Or amending it with anything?
@dmykins All I do is start to adding nutrients about 2 weeks in. I use only FF Trio liquid and powder. This grow I am trying the Dirty Dozen box set.
Since its depleted I do this. Soak seeds up to 24 hours. Transfer to damp toilet paper for 48 hours. Then transfer seeds with tap roots to their forever home. Place in tent. After 2 weeks I will start feeding accordingly. I am now do pH of my water so instead of 8.7 they get fed at 6.5 or close to it.

I reuse my soil for everything but cannabis.
I reuse mine. All you do is use nutrients faster than brand new soil.

I’m running off well water with a ph 6.8 and only used Fox Farm nutrients last year,should I do anything to the soil?
You could add amendments like blood meal, or feather meal.
Thank you,should I also add cal mag to the soil or water it in with my other fertilizer?
