After using the Plant Runner indoor plant food and seeing the great results it had on my plants, I was thrilled to see the 500ml refill. Great value, for perfect looking plants.
I liked the first one so much I bought the refill to use in the smaller dropper bottle. Unfortunately, in refilling the smaller bottle I spilled a bunch on the counter as the bottle opening isn't great (lots spills along the big bottle itself). I suggest using a funnel or better yet, adding a spout pourer like they have in olive oil bottles so it's easier to pour.
An economical refill for my plant runner bottle.
