Anyone have a good ratio of soil medium to Perlite? I've been having issues with poor drainage/ water absorption and want to add my own Perlite. I can see tons of people are clearly using a high ratio. I would appreciate all you fine people feedback.

Hey gardener! You need to mix about 30% perlite or coco to aerate your mix. Good luck to you, bella ciao!

Depends on the composition of the soil mix really. 20% is prob standard for soil. some need higher others less or none. You can also mix in coco coir, about 10-20% to improve water retention along with the perlite.

I use Pro-mix premium potting soil, which has some perlite in it, though they don't tell you the exact ratio and I found the soil's drainage last grow left something to be desired; I had no issues related to it, but to avoid stagnant water only being slowly absorbed by the soil, watering/feeding could take as long as 15 mins in the last weeks. The same company also makes pure perlite, and for this grow I bought a bag to mix in some extra. I didn't need to add much, but they don't tell you how much is in the premium potting soil and you can't really estimate the ratio when its already mixed in. But I added an extra 15% of perlite to 85% of their potting soil with an unknown amount in it already, and after mixing it all up, watered it just as I would water a plant in a 3 gallon: I put 1.5L of water into it and it absorbed it like quicksand, with a small amount running off at the end. Their recommended ratio, if adding it to soil with none present, is 1 part perlite to one part soil for an outdoor grow, and 3 parts of soil to one part perlite if growing indoors. I used less since their potting soil has some in it, and just adding in an extra 15% of raw perlite greatly improved drainage.

This is what I found on the net How Much Perlite to Add? Add 10-20% perlite if you want better water retention and don't plan on using a lot of extra nutrients. This is because a lot of extra perlite can cause the nutrients leach out faster from the soil as water drains through easily. Add 30-50% perlite if you plan to use a lot of added nutrients or supplements and are looking to get the fastest growth from your plants. maybe 20-30% would be pretty safe spot! 👌

Hello.. Hope you are well.. It is entirely up to u.. I wud personally use a ratio of 2cups soil to 1cup perlite myself as u know u have more oxygenation in ur roots while still maintaining easy operation to ur soils needs.. Remember u will need to start ur feed program abit earlier than usual compared to just soil grown tho.. Stay safe n gud luck.. 👍🍀
