Chunky Potting Soil (Designed For Aroid Plants)
Kaz
Happy plants!

My plants seem to be happier already! And great not having to find all these ingredients myself, to make my own. Service is fast & efficient also. Definitely feels like a more premium soil for my plants’

Thanks Kaz! Love hearing your plants are already feeling the difference. So good not having to muck around sourcing all the bits yourself too. Stoked you’re happy with the quality and speedy service!

Thanks Glenn! Love hearing the pH Down made such a difference—nothing like dialling things in and seeing the plants respond. Appreciate the recommendation and your support, legend!

Green Planet Pro Cal (1L / 5L)
resmond.
Green Planet PRO CAL

Green Planet PRO CAL is a top tier liquid Calcium Magnesium supplement that provides superior bang for you buck. There are many great Ca Mg products on the market, but the Green Planet PRO CAL is a mainstay in my horticultural toolkit. Besides the ease of use and simplicity of the product, one of its greatest advantages is its low nitrogen (N) content, which means you can continue to supply vital quantities of Ca Mg right up to the final week(s) before harvest whilst letting nitrogen levels in the plant and media deplete naturally in the final weeks of flower, resulting in superior quality flowers. Ca Mg is an absolute must (especially for coco media) and if you are looking for a quality product to use in your next grow, Give it a try, you'll be more than satisfied!

Thanks bud! That’s an absolute ripper of a breakdown—love the detail. Spot on about the low nitrogen too, makes a huge difference late in the game. Appreciate you sharing your knowledge and backing the Pro Cal, legend. Happy growing! 💪
