Organic aeration to add to your substrate blends
Key benefits
Orchid bark is an excellent organic aeration medium to add into substrate blends. From fine to large it can be used in bioactive grow bins and chunky aroid mixes respectively, with endless possibilities in-between. We even grow some orchids exclusively in bark. Just be careful not to overwater as water retention is long-lasting and a dry surface in pots can be deceiving.
Fine Grade: 2-7mm

Fine grade orchid bark receives excellent ratings for quality and value. Customers said "great quality for the price" and praised accurate sizing. Popular for creating custom substrate mixes for indoor plants and orchids. Occasional minor concerns: one shipment arrived slightly wet with traces of mold. Overall highly recommended.
Good quality and I like the size of this, not too chunky so good for finer mixes
Exactly what I needed.
Great quantity for the price and no mold or white dusty areas. The description of the size of the pieces is exactly as described. I have found that the size described from other sellers are wrong, which leads me to manually cuttinf up each piece for the size I want. I think I am now addicted to mot only ordering plants from growtropicals, but also different substrate materials because I like to make my own mixes depending on what plants need repotting.
Making up my own bespoke potting mix for indoor plants, great purchase.
Second time buying. Prefer it to the medium grade. This stuff has been great so far.
Great product, really good quality. I bought to mix more into the other substrates, and this is a good quality bark.
Shipping was quite quick too.
Great little peaces of bark and well packaged, although it came slightly wet and had minor bits of White mould at the bottom, but I generally would recommend this product and the people behind it, thank you
Excellent quality bark, moist but not soggy and none of the splintery bits.
Great quality. Nice size bark. Very happy
this is good quality fine bark. Have used some as a top dressing on an existing pot. Used more mixed with other ingredients. Happy with the results.
I initially was weary as trying a new online plant shop can be scary but GrowTropicals have exceeded my expectations. My plants were packaged so well and arrived safely. Not to mention they are sustainable!?!?!?!???! Love that. So yeah, I will 100% be ordering again.
Good quality
Excellent quality bark.
Perfect
I haven’t used the orchid mix before but it looks like a good quality mixture
The bark is finer than I expected, but the bark is high quality as always :)
My order was delivered fast and the quality of the product is excellent, my only concern was that I ordered fine lava rock and it's not the same as the order before, it's bigger and is like a medium grade maybe a mix up but still 5 stars
Great quality product. Wouldn't buy my substrates anywhere else!
Really happy with all planting mediums that I received. Shared some with friends and will need to re-order soon.
Fab product and quick delivery
Yet to use it, but I'm sure my orchid will love it.
