Dr Greenthumbs Root Roids (Root Health & Plant Support)

Root roids run amok

If these root roids don't give me day of the triffids I'll be ok with that so far so good

Thanks Christopher! Love the Day of the Triffids reference—here’s hoping your plants grow wild (but not *that* wild!). Glad to hear things are off to a good start. Appreciate the laugh and the feedback, mate!

Purecrop1

Purecrop1 has been my absolute go to product for IPM and organic pest and mould control for years. Use from germination through to post harvest wash and protect your investment. If you haven't used it before, try it for yourself, you won't be disappointed with its effectiveness and value for money. Quit gawking at the reviews and put it in your cart already!

Thanks legend! Love the passion—couldn’t have said it better myself. PureCrop1 really is the go-to for a reason. Appreciate you sharing your experience and giving others the nudge to get on board. Here’s to pest-free, thriving plants!

Can’t believe the difference

Have been using a high grade potting mix plants have not been happy slow growth and just not looking healthy. So I took them out of pots removed about a third of the old dirt from the bottom and anything that fell off the top and sides cleaned out the pot put turbo dirt in the bottom put a scoop of roids on the bottom and a tad more turbo dirt over it and sprinkled some transplant powder on the soil at about a third of the way up refilling with turbo dirt and then sprinkled another scope of root roids and some powder down the sides topped up with turbo dirt and a slight top dress and just before the top dress another scope of root roids and then covered with about 20 mm more turbo 2 lts of water. I could see a difference in 2 days could see a darker green coming up through the leaves in a week they where no longer sick and now 2 weeks later it’s like a different garden I can see daily grow. Can’t believe how much difference turbo dirt made thanks for your help.

Thanks Wayne! That’s an absolute ripper of a review—stoked to hear the garden’s loving the Turbo Dirt and Root Roids. Sounds like you’ve given those plants the royal treatment, mate! Appreciate you sharing your results and the play-by-play. Here’s to happy, healthy plants and plenty more green days ahead!
