i dont know if its possible, it seems kinda dirty but i have some trees that went hermie and the roots are are probably not deep into the rockwool.

i have a 3 inch cube on top of a hugo 6inch cube. would it be a bad idea to re use the rockwool?


i ran out of blocks and i wanted to throw some other sh*t into 1212 but i dont have the 200 bucks to buy a box of rockwools right now.

thanks in advance for any input

i try to buy them by the box. the 6inch hugos come 48 to a box.

do you do 12/12 in the 4 inches too?


i was thinkin about rinsing them real well but i'm probably just gonna wait

My concern is that there would be nutrient residue at a level too high for new plants.

lol, I am a re-user of rockwool! Every time I pull a godammed male trying to grow those "special" non femmed seeds I just repot that shit into the next pot. I use it also all oer the place, and have I have cut cubes lying about. Lol.

pretty much to sex I use a 4 inch cube and let her veg a month and usually I get preflowers by then. Then I stack it on the 6 inchers.

This is as far as I ahve got in my rockwool pyramids. They work great but I am moving to dwc as I want some trees as I am legal and prefer a 4 in veg and 4 in flower formula for my ladies.

Once it gets too dried out tho it is worthless. You will notice that flat overly hard look that wont "wash out". Let that go.

hey fireman i use both 4x4 & 6x6 but by the time i go 12/12 i put 3'' mat under blocks works killer i flood once a week or 10 days depending on moisture content i might try the new 8x8 blocks designed to grow whole plant start-2-finish but hard to argue with success im having with current method i see no harm in re-using blocks if nute level isnt high & no roots grew into them rotting roots could really cause problems

i like to call them donator plants instead of mothers. Mother fuckers. Lol. I have this donator in dwc and these others in rockwool blocks and I let this donator just sit there for 3 months or so in dwc and I could not have done that in rockwool. Also I could cut the roots if it got bigger than my place. I know I could just remake the donator out of clones but then I would not get to flower a 3x3 tree in dwc either. I am switching over to dwc for all my plants really tho cuz this is so fun.

I kniw this was a rockwool thread but I am so happy no more rockwool in a way. A mess is a mess. If I needed a medium then it will always be rockwool. Pyramids do work.

thanks for the rep.
