    Q: Is this soil good for a container Meyer lemon tree?

    4 years ago
    2 Answers
    • A: HP PRO MIX is a high porosity soil meaning it dries out quickly and requires A plant to be watered more frequently. Typically every other day so this as an only Material wouldn't be good for a lemon tree

    Q: Can this product be used for cannabis seedlings ?

    4 years ago
    2 Answers
    • A: While it is one of the best soilless media for cannabis, the high porosity which provides a quick wet/dry period makes it less than ideal for seed starting and seedlings. While using Pro Mix for I simply mix in a large amount of worm castings which not only provides lots of nitrogen and minerals, but also helps it retain moisture for longer periods between watering making it better for seedlings.

    Q: I’m replanting a 5 foot ficus tree that has outgrown its current pot and this seems perfect. Will I need to mix it with any other type of soil or will this do on its own? Thanks!

      A: Hello rgrth, this product contains sphagnum peat moss (65-75%), perlite, limestone for pH adjustment, wetting agent and mycorrhizae. You could add some coco fiber or compost to help retain moisture. Thank you.

    Q: Can Pro-Mix HP Growing medium be used as a soil amendment in the garden? We have heavy clay soil (almost solid clay) so need to amend it - particularly for aeration.

    • A: No ,I would suggest you don't ,better is to use compost & peat moss & sand .Short term it works but you end up with just the vermiculite ,after a couple of years, and as that breaks don it affects plant growth

    Q: What is the Ph of Pro-mix HP with mycorrhizae?

    3 years ago
    1 Answer
    • A: With the lime that is already mixed in it keeps it right around 7 (neutral) - if you add some organic matter ie. leaf mold, worm casings they will bring it down slightly to the perfect pH for cannabis.

    Q: What’s the difference between this and regular peat moss?

    5 years ago
    1 Answer
    • PRO-MIX Expert

      A: Hello Winnie, Regular Peat Moss contains only 100 % roughly screened peat Moss. PRO-MIX HP is a ready to use professional horticulture grade mix. With its high perlite content, PRO-MIX HP provides a great growing environment to growers looking for a significant drainage capacity, increased air porosity and lower water retention. The added benefit of fibrous peat moss and coarse perlite makes this formulation ideal for growers who require a superior-quality product adapted to their needs for watering flexibility and crop seasonality. It contains Peat Moss, Perlite, Limestone, Wetting agent and Mycorrhizae. Thank you.
