    This plant food made my succulents explode with growth! They are suddenly huge rosettes trying to push each other off the windowsill and I’ve had to remove some as not enough space. Been good for all my plants. Couple important things though! It says it has seaweed in it, it doesn’t… It smells like fish skins and molasses I think.
    So yes it is organic and yes it works and as long as you mix it fresh and use it all straight away it won’t smell to bad. However, if you leave a small amount in your watering can in your kitchen or living room, you will regret it badly! By the next day, you will be looking to clean your drains mistakenly :-) also I found that as others have said even though shaking the container every time, when it gets to the end, there is a lot of sludge at the bottom... And then I made the biggest mistake ever! I added some water to the container and shook it well using only some of the stuff leaving the rest in the bottle. The next time I went to get the bottle out from the cupboard it had a blown up into a bulging balloon threatening to bust the lid off as obviously the contents were fermenting very strongly! Needless to say, it was very gingerly taken out to the bin and thrown in before it blew up in my face :-) I would use it again, but I won’t make those mistakes again. Organic after all is organic and is much healthier for us and the planet. It would have been nice to actually have had seaweed in though as my tomatoes would have appreciated that.

    I was really pleased to find this product at the original purchase price. I paid for a monthly then fortnightly subscription. There were some mild fluctuations, but overall 4 x 1 litre units would cost between £20.50-27.20 - suddenly in June, the price skyrocketed by another £7 so now the cost per unit is almost £9. Great product, but no longer value for money from this vendor so subscription has been cancelled.
