Carrying anything more than 10 to 15 6" cubes (rockwool) becomes obvious when you leave the store. Making several smaller trips is obvious too. Hydro stores are watched by not only Law Enforcement but other not-so-pleasent folks and I want to avoid all that if I can.

I know a grower who gets terrific results using Rockwool cubes exclusively. The 1" for clones and the 6" for growing. Very large yields in less than 90 days and extremely good quality too.

I am hoping that the mix of Peat and Pearlite will avoid the two characteristics you mentioned. Just as cement, sand and aggragate mix is much better/stronger than just any one of the components by itself is. (for making concrete)

Just looking for advice if anyone has tried this.

thanks,

Max Blast Reviewed by Max Blast on . Home mixed growing medium, Pearlite? I am currently using rockwool cubes and a drain-to-waste system but for my next grow I would like to make a change. Is there any reason I cannot use a mix of Peat Moss, Pearlite and/or vermiculite for the growing medium? What mix should I use and what steps are necessary if any? Any precautions with such a mixture? Is straight Pearlite a better choice? :confused: I just do not like coming out of the local Hydro store carrying a big load of cubes. :cool: I have no problem getting big Rating: 5
