Discover the award-winning power of Growth Technology Silica, the proud winner of the 2025 Tropical Plant International Expo (TPIE) Best New Product Award as voted by 7,400+ industry professionals. Known as "Nature's Bodyguard," this revolutionary plant strengthener provides the missing link in indoor plant nutrition, delivering the natural protection that plants receive outdoors but desperately need in our homes.
Why GT Silica Won Industry Recognition
- Industry-Voted Excellence: 2025 TPIE Best New Product Award winner, recognised by thousands of professional growers as the breakthrough innovation in plant care technology
- Superior Potassium Silicate Formula: Advanced blend of silicic acid and potassium hydroxide in the superior potassium silicate form for maximum plant uptake and effectiveness
- Variegation Specialist: The dream solution for variegation lovers - helps prevent browning on variegated leaves by strengthening the chlorophyll-free white sections that are naturally vulnerable
- Cell Wall Fortification: Strengthens plant cell walls creating stronger stems, better disease resistance, and increased tolerance to environmental stresses
- Natural Indoor Protection: Provides the silicon that plants naturally access outdoors but miss in indoor environments, acting as nature's own plant bodyguard
The Science of Silicon Enhancement
Cell Wall Strengthening: Plants deposit silicon in their cell walls, creating a natural barrier between plant cells and environmental challenges. This fortification results in stronger stems, improved drought resistance, and enhanced disease protection.
Variegated Plant Specialist: Silicon helps slow and prevent browning on variegated leaves - a dream come true for collectors of Thai Constellations, Albos, and other premium variegated plants. It strengthens the variegated portions which lack chlorophyll and are naturally more vulnerable.
Professional Benefits: Reduced water loss through leaves, increased nutrient uptake, improved CO2 absorption, and comprehensive stress resistance make this the ultimate plant insurance policy.
Application Guide for Australian Growing
Hydro/Semi-Hydro Systems: Add 5ml per litre of water for optimal benefits in LECA, passive hydro, and water-based growing systems.
Potting Mix Applications: Use 2-3ml per litre of water for soil-based growing. Add GT Silica to plain water first, stir thoroughly, then rest for 15 minutes before adding other GT fertilisers.
Professional Protocol: Add silica solution, stir vigorously, rest 15 minutes. Add regular GT nutrients, stir again, rest 15 minutes. Test and adjust pH to 5.5-6.5 for optimal uptake.
Flexible Dosing: Use up to 5ml per litre for maximum benefits, or reduce to 1ml per litre for budget-conscious plant parents - any concentration provides significant plant improvements.

Shipping & Greenhouse Collection
Let's Talk About How Your Plants Get to You!
Alright, so here's the deal with shipping - we try our best to send all our plants potted and ready to go, but sometimes due to larger orders or when we're moving through some big changes, we'll send some plants semi-bare rooted. If you haven't come across this before, it basically means we carefully remove a bunch of the soil before packing them up. I know that might sound a bit scary if you've never ordered plants online before, but trust me, this is actually a really smart way to do it! The main reason we do this is because it creates so much more room in the box, which means we can fit way more plants in one shipment for you. More plants in one box = more green goodness arriving at your door at once! The plants honestly handle the journey better without all that heavy, wet soil sloshing around too. Just make sure you've got some fresh potting mix ready to go when your green babies arrive, because they'll want to get tucked into their new home pretty quickly!
Now, let's chat about what actually fits in our boxes. We can safely fit about 4-6 plants in one box, or if you're stocking up on supplies, one box can hold 3 bags of medium plus 1L of Growth Technology. We really don't recommend adding heavy items with your plants though - it just puts extra stress on your precious plants during transit and limits how many we can fit. If your order ends up being heavier than our standard box can handle, we'll reach out to you about additional postage fees. We're always transparent about costs, no sneaky surprises!
When Does Everything Ship Out?
Here's how our timeline works - we process and ship orders the week after you place them. So if you order on a Tuesday, your plants will get packed and sent out sometime the following week. We ship Monday through Friday (because let's be real, we all need weekends to recharge!), and we're aiming to get your order out within 4-6 business days of processing. Sometimes things take a tiny bit longer because we're a small but mighty team, and we take absolute care in making sure every single plant is packed perfectly. Like, we're talking individual attention for each plant here. We don't rush this stuff!
Once your order ships, you'll get an email with your tracking number. If you haven't received that tracking email, it just means we're still working on your order - it hasn't left us yet. Please be patient with us! We promise we're working as fast as we can while still making sure everything is done right. We pack orders in chronological order to keep things fair for everyone, so no one's getting special treatment or jumping the queue. First come, first served, that's how we roll!
The Journey to Your Doorstep
All our orders ship with Australia Post, and here's something cool - they operate 24/7! That means even if your order gets sent out on a Friday afternoon, it's still making its way to you over the weekend. The postal system doesn't sleep, and honestly, that's pretty amazing for getting plants to you quickly. You can generally expect your plants to arrive within 2-7 days after we ship them, depending on where you are in Australia. Metro areas tend to be quicker, regional spots might take the full week, but either way, your tracking number will keep you in the loop the whole time.
And here's the thing that always blows people's minds - our plants are absolute troopers. We've tested this extensively, and they can genuinely survive in their boxes for up to three weeks if needed. Obviously we don't want them sitting around that long, but life happens, mail gets delayed sometimes, and we want you to know that your plants are prepped and ready to handle whatever the postal system throws at them. While we do our best to avoid delays, occasional unforeseen circumstances may slightly impact delivery times, but rest assured, your plants are packed with extra care and are tougher than you think!
Quarantine States (WA, NT, TAS)
We currently only ship directly to non-quarantine states. Unfortunately, biosecurity restrictions make it pretty complicated to send plants to Western Australia, Northern Territory, and Tasmania. But don't worry, we've got a solution for you! If you're from a quarantine restricted state and would like to purchase plants from us, we recommend using Paradise Distributors' concierge service. They're absolute legends and can handle all the biosecurity paperwork and requirements for you. Make sure to contact them prior to purchasing so they can give you all the details and help you out: info@rareplants.net.au
Come Visit the Greenhouse! (Rockdale)
If you're local or just love the idea of picking up your order in person, we've got you covered! Greenhouse collection from our Rockdale location is available the same week you make your purchase. Our opening hours are always changing, so make sure to check booking availability on our 'Visit the Greenhouse' page before purchasing. After you've paid for your order, just head over and book a time slot that works for you. You'll get to pick up your plants AND have a wander through the greenhouse while you're here, which honestly is such a vibe. Just please wear a mask if you're feeling unwell - it's a small space and we want to keep everyone safe and healthy!
Catch Us at Markets!
We do regular markets around Sydney and would love to meet you in person! If you'd prefer to skip shipping altogether and grab your order at one of our market stalls, just email us at info@growinggroundsaustralia.com and we can arrange collection at an upcoming market. It's a great way to chat plants face-to-face, see what else we've got on the day, and save on postage!
