Originally designed and developed for the Atlanta Botanical Gardens (hence ABG), this has been the go-to mix for vivarium and terrarium enthusiasts for years.

Our ABG mix is based on the original Atlanta Botanical Gardens substrate recipe. It is fern fibre based and designed for long life span. ABG is designed for long term use in humid vivarium because of the following qualities:

Fast draining – it's a porous airy mix that doesn't get bogged down.

Moist but not boggy – the components, whilst fast-draining, do retain moisture well to prevent root dry out.

Nutrient retention – whilst the mix itself isn't nutrient heavy, the components hold onto nutrients well, ensuring a good growing cycle.

Minimal compaction – due to fibrous components, it's very resistant to compaction over time.

Long lasting – ABG can be used for a number of years before needing to be replaced.

  • We always aim to make sure our customers love our products, but if you do need to return an order within 14 days of purchase (not including plants*), or any items are damaged, we’re happy to help. Just email us directly at hello@growtropicals.com, and we’ll take you through the process. 

    Please note: we cannot be held liable for any packaging costs should the original packaging be discarded.

    *Unfortunately we cannot accept returns of undamaged plants as these are perishable items and are not saleable upon return. If a plant is damaged, we will compensate for this as per our live arrival guarantee.

  • When placing your order, you can choose from three dispatch speeds to suit your needs: Economy (prepared and shipped within 4-5 days), Standard (3-5 days), or Express (dispatched the very next day). Please keep in mind that "dispatch" refers to the time it takes our team to prepare and pack your items before handing them over to the courier, not the total delivery time.

    Shipping costs are based on your total order value and will be calculated at checkout, with free shipping automatically applied to all orders over £60. For a full breakdown of shipping prices please see our help center here.

    Additionally, to protect the health and quality of our live plants, orders containing plants are exclusively shipped Monday through Thursday. This careful scheduling prevents your plants from being stuck in a dark shipping depot over the weekend, ensuring they arrive at your door vibrant and healthy.

The moss seems too big and personally too much I feel.

Hi Jitesh,

I'm really sorry to hear that you're not happy with the quantity of moss in
our ABG mix.

If you could send us some photos of the mix, along with your thoughts, to
hello@growtropicals.com, we would be more than happy to offer a resolution
this for you here.

Although I’ve not used it

Although I’ve not used it yet, I can see it is a high quality ABG mix. It was expensive but I will be buying more as I doubt I could find an equal alternative.
