Excellent plant food.
I bought this as the 1 litre bottle is almost empty. The price per litre is much cheaper and will last nearly a year. This plant food has given my container plants a real boost.I've used it for 2 months,and despite the frequent heatwaves my plants are in full bloom,healthy foliage.I'm very pleased.

Good product, don’t use too much
Good product helps the grass to grow. All I would say it don’t use too much as it can cause ph imbalance in your soil, leading your lawn to go yellow

Love it.
This is the best purchase I’ve ever made. The quality of the feed is very good, and you only need a small amount for the five litre can. My flowers are looking happier and stronger now. It’s a great value for money, and I’ve been using it for a month now, and there’s still plenty left. The smell is fine, but that’s not the most important thing to me. I love the size and design of the bottle, and how they made it is incredible.

Easy to mix and use, good value lawn and vegetable plant treatment
We’ve been using it for some weeks now to feed our lawn and vegetables and have really noticed the difference. Previously our lawn was patchy but with this treatment the grass seems thicker and stronger and green. It’s easy to use, measurements are given just follow the instructions.

Good product, flawed bottle design?
Product seems good, plants respond well when watered with a liquid seaweed solution. However I find the integral measuring reservoir difficult to I use and therefore won't be buying again.

livraison très rapide, dans un carton, gros bidon à bonne odeur maritime et j'espère que ça va fonctionner après les autres (sucre de canne et guano^^) pour mes plantes d'intérieur peu résistantes pour l'été, et pour leurs feuilles bien trop petites. En tant que bretonne, j'ai confiance dans les qualités des algues, que je vais mixer en brumisant fish-mix de biobizz, un essai écolo à voir...Essai qui fonctionne parfaitement, que je fais tous les samedis : les plantes adorent, droites et bien vertes, avec bourgeons sans arrêt, je recommande cet engrais que je reprendrai dès que vide!

è dotato di un dosatore sul tappo che garantisce l'esatta misura d'uso nel miscelarlo in acqua. L'etichetta dà le corrette indicazioni. inoltre evita sprechi, anche se occorre porre attenzione durante il versamento perché la bocca del contenitore non ha una guida di fuoriuscita. Nei vasi di fiori o piante ornamentali è eccezionale. nel mio caso i risultati sono visibili già dalla prima settimana. Un po' meno per le piante dirette nel terreno per le quali forse ci vorrebbe un'innaffiatura molto copiosa usando questo fertilizzante che lo rende poco conveniente. Però dove l'ho usato, alberello di limone in aiuola o pianta di rosmarino direttamente a terra etc. ho rilevato che in maniera parziale, c'è stato un buon rinvigorimento. Non sono un esperto per cui lascio ad altri i confronti con altri prodotti.

El envase es tal como se describe. Primero hay que llenar la cavidad donde se aloja la dosis, que se consigue desenroscando el tapón y apretando un poco el envase. Es fácil. 👍 Llevo dos semanas usando el fertilizante y aunque es un poco pronto para juzgar sus resultados, parece que funciona. Estoy dispuesta a ponerlo a prueba con un rosal que me he encontrado hoy literalmente al lado de los contenedores de la basura. Cuelgo la foto. Hoy día 15/07/2021 le he dado su dosis. Volveré en dos semanas y os paso nueva foto. Voy a probar de ser lo más objetiva posible. He calculado la dosis según instrucciones del fabricante. Como veo que el rosal esta muy paliducho, le daré una dosis de recuerdo de aquí una semana. 😊 👌Escribo esta reseña en fecha 29/07/2021, es decir: han pasado dos semanas. El rosal que me encontré ha recibido dos dosis de fertilizante en las cantidades recomendadas por el fabricante. A parte de ello, lo he ido regando a demanda. El resultado es muy bueno. El resto de mis plantas, también han rejuvenecido, y un olivo que pensaba que estaba muerto, ha rebrotado como si de un milagro se tratara, después de dos meses de no dar ningún cambio. Espero haberte ayudado a encontrar el fertilizante que andas buscando.
