is it safe to reuse the soil of a harvested plant? say for example i have a plant that has gone 9 weeks and i cut it to harvest. is it good or bad to re use the same soil? why or why not?
it is quite alright and I do it all the time. I do use 1/3 old soil to 2/3 new soil as a rule of thumb.
Listen to this man here. Many growers have learned over the years the value of saving what you can, where you can. Pennies soon mount up.
thanks and i can easily go buy it but im just asking the questions that come to me so the more i know the better im off. I think ill try to do both and see the difference.
imho the pennies you save using old soil, will be spent on replacing the nutrients that aren't there anymore.. never tried it so it's just my .02
i hear you and it makes more sense to buy soil and start fresh but i just wanted to know it was ok do it the other way. thanks for the info and ill be sure to buy new soil when i start over.
i'm sure it's fine man.. just don't know how much cash your actually saving is all. Also if your gonna do that just inspect the soil really well for critters and stuff.
And make sure to flush it thoroughly first, since salt buildup that might not bother a mature plant could overwhelm a new sprout,
You only have .02 because you are always buying new soil. August is right. You will spend the same amount of $ replenishing. Plus you would need to deroot the old soil. I reuse 100% of my old soil. Just not for my mj. I built an above ground garden in the back yard. (its below ground level for now) I just mix a couple bags ($1 a pc.) of top soil with my old dirt,and spread it in my garden. I don't waste any soil and it grows some kick ass veggies.
