i dont use lime what i do is the last 2 weeks flush with ph'ed water! i use hydro nutes the soil is just a media that contains fuck all after the flush it basicly hydro grown in spent out soil the hydro nutes supply all the nutes, but the soil supports the plant from falling over.good im glad to see that im not the only one who is tired of buying soil...40 a bag wow. I thought mine was bad at 18.
9inch bigbud - how much lime do you use and what do you amend with? peat will also lower the soil ph over time.
go through the dirt with my hands and take out the big roots. but as already mentioned they will become compost if you keep reusing it.
I too would be skeptical if my plants didnt do good the round before and then reusing the dirt for the next grow...

Lime(calcium carbonate) is a base, it'd increase PH.i re use soil just watch the PH it will rise the more you use it that is because of the old roots . bring the PH back down with lime or if like me use hydro nutes on soil this will buffer
the soil ph for you. the soil in these pots have been usesd for over 4 grows
ps
if your plants become sick then throw the old soil out and start again with fresh soil and bleech the pots be for reusing.
I've heard of this but it seems like it would take forever and stink the house up like a mother fucker.Just take your dirt, spread it thin on an oven-safe sheet, and toss it into an oven preheated to 450 and bake it for a couple of hours.
Never worry about root rot in soil caused by older roots ever again. Also, say adios to any fungus, bacteria, and insect larvae you may have had sneak into your soil.
Nature reuses soil every second of the day. Marijuana is a great soil reconditioner.
cooking in the oven? are you trying to kill off the bugs? cause that's not the ONLY thing you kill! healthy soil is actually a microcosmic boisphere (too complicated?)...there are processes involving micro-organisms, fungi,bacteria, bugs...they all have a part to play...I have all kinds of bugs(yes-indoor)! my army of spiders are paid in food! my plants have ZERO bug problems; because my soil 'lives'...in symbiosis. .I wish I could bottle my aftersmoke as an air freshner! that's what the hippies really meant by 'kind' bud. the stuff(soil, plants,and finished weed) exudes lifeforce! worm castings? hah! try teeming with worms!not even when it's cooking in the oven? lol
