Frequently Asked Questions
What is Root Roids and what does it do?
Root Roids is a microbe-packed root inoculant with mycorrhizae, Bacillus, and Trichoderma. It boosts root growth, improves nutrient uptake, and helps plants bounce back from transplant shock or stress. It’s not a fertiliser—it’s biology that makes your nutrient program work harder.
Which plants and grow styles is Root Roids best for?
Root Roids works in soil, coco, and hydro, and it suits most plant types—vegetables, herbs, ornamentals, and edibles. Avoid in heavy-sterile systems. Brassicas may show limited benefit due to low mycorrhizal response.
When should I start using Root Roids?
Start as early as possible—at seedling, cutting, transplant, or first pot-up. Root contact is key, so apply directly to the root zone or media. For single-use growers, transplant time is the highest-impact moment.
How much Root Roids do I use, and how often?
Use ½–1 scoop per litre weekly in soil or coco, or ½ scoop per litre fortnightly in hydro. For seedlings, go lighter (¼ scoop per litre). Water it in well so microbes reach the roots. Stop in coco one week before flush.
Can I foliar spray Root Roids?
Yes—mix ½ scoop per litre and spray at night to reduce leaf stress. Avoid spraying near walls or porous surfaces, as it may stain. Foliar is optional; root application is more important.
Can I use Root Roids in hydro or irrigation systems?
Yes, but clean systems are essential. In hydro or autopots, don’t let Root Roids sit warm for days. Keep tanks small and fresh, use filters, and maintain flow to avoid clogging or biofilm buildup.
What can I mix with Root Roids?
Root Roids plays well with most base nutrients and compost teas. It already includes mycorrhizae, Trichoderma, and Bacillus, so extra additives are usually unnecessary. Avoid using it alongside sterilants like peroxide or heavy fungicides.
Does Root Roids really help with growth or recovery?
Yes—users often see faster transplant recovery, better root mass, and improved growth within 1–3 weeks. It can help reduce nutrient lockout, drought stress, and even cut fertiliser needs over time (if adjusted slowly).
How should I store Root Roids?
Store Root Roids sealed, cool, and dry. Don’t let moisture into the bag—clumping reduces quality. Avoid scooping with wet tools and keep it out of the sun to preserve microbial viability.
Is Root Roids safe to use around pets, kids, or food crops?
Yes—Root Roids is commonly used on food gardens. Just apply responsibly: store safely, water it in after application, wash hands, and don’t inhale dust. Wash edible produce as usual before eating.

I used root roids powder feed, the transplant granules for 1 repot and some basillicus granules.
Have had an incredible root and growth rate. Unlike any combo ive found previously.
Amazing work. Great care has gone into developing these products.

I’ve fitted the filters to both of my taps and no longer smell chlorine when watering and can even drink from the hose happily now!
The plants look greener and healthier and I can safely mix my fabulous Root Roods in the clean water and not have to collect rain water. Thank you again!
Thanks David! Love hearing you've gone all in with filters on both taps! No more chlorine smell, healthier-looking plants, and being able to mix up your Root Roids straight from the hose is a massive win. Cheers for the awesome feedback mate, really appreciate the support! 🙌
T-drops are pretty good, they do work if you use neem oil with it and use every couple of days. I do prefer gnat barrier abrasive granules as they tend to keep them away more long term. Unfortunately t-drops only work short term and is a constant battle and not fixing the problem completely.
Thanks for giving T-Drops a go! You're spot on with they aren't a complete control solution. They're designed to help keep numbers low, not eliminate them entirely.
If you're dealing with a recurring or persistent issue, it's worth looking at the underlying causes rather than relying on a quick cures. Used as part of a broader approach, T-Drops can be a really handy tool for keeping populations under control. We appreciate you sharing your experience and feedback!
