Genuine product and service

My plants are already responding to silica and grrenspace fertilizer with more rapid stronger growth. Feels like silica has been something vital my plants have missed till now. Value for money is terrific as it makes 100s of litres. Service from Dr Greenthumbs has been awesome with Scott answering all my questions and delivery was so fast!


Absolutely LOVE! Must have for variegated plants like monstera Thai and albo. Since using GT silica I’m getting beautiful leaves with no browning! My other plants are all putting out new leaves too and loving it. Shipping was fast and easy, and I appreciate the follow up making sure everything went okay with the delivery from Dr Green Thumbs. Will be buying from here again

So far so good, great shipping!

So I can’t give an in depth opinion on the fertiliser as I only just started using it, but I finally made the plunge to start using growth technologies fertilisers and a ph testing kit (I grabbed this and foliage focus plus a ph testing kit) I’ve never used this website before but they have the best prices and range of products and I’m so glad I did, they were shipped quickly and arrived quickly, and after one lot of watering 70 indoor plants and change a hydro plants water nothing has keeled over so fingers crossed it works out!
