styrofoam beads instead of perlite in hempy system?

[PoTSD]

Hi. WHere I live I need to buy huge quantities of specially ordered perlite and vermiculite. I am interested in trying the Hempy bucket indoor method and looked on line and saw that styrofoam can be substituted for perlite. Does anyone have any experience with this ? Advice? Perlite substitute ideas? Thank you

Find out what they are made of before you buy them. Some of them are starch based and biodegradable and will dissolve in contact with water.

thanks for that awesomely quick reply. I was thinking of simply taking old packing material from our recycling center and bashing it down to beads

never heard of styrofoam being used in a hempy, but it might work okay

in the WOH thread, they talk about someone who had used the foam from an old sofa and had good results

BTW you don't really need vermiculite, as many of us have grown with straight perlite

Let us know what you end up doing, I would be interested in hearing

I will and I thank you for taking the time to reply also

Perlite is made by mining a volcanic obsidian type rock, crushing it, superheating it, and it pops like popcorn into like 15X it's original size. So it's a 100% organic material. Sometimes you willl see a slight Nutrient NPK analysis on a bag like 0.04-0.01-0.06.

Typical elemental Chemical analysis is all things a plant can use, (like oxygen or air !) doubt if styro allows exchange of air into the pellets or your coffee cup would leak.

Silicone: 33.8 %
Aluminum: 7.2
Potassium: 3.5
Sodium: 3.4
Iron: 0.6
Calcium: 0.6
Magnesium: 0.2
Traces: 0.2
Oxygen 47.5
Bound Water 3.0
Total % 100.0


Styrofoam is made from petroleum, and invented by Dow Chemical. I don't think my plants need petrochemicals, but you may be on to something.

Perlite is dirt cheap.

Nuff said ?

Styrofoam can break down easily into little bits that work there way into everywhere. there are bound to be issues.

Mr. V you're most probably right but here I can only buy 100liter bags specially ordered. I am talking two plants.. Its not ideal, but like they say.. Necessity is the mother of ....who? Thanks for the reply

Clean River Sand is a better option

for a Hempy clay hydroton balls are the best

or crushed wind screen glass if poor

good luck
