Has anyone ever used this brand? Stumbled upon and decided I need one considering I’ve never use any sort of fertilizer for my houseplants (and yet I’ve owned plants already for 4 years now). Was a bit nervous to do it to my plants so decided to test it out on my small spider plant (I have too many spider plants lol). Does it works well for you? Are your plants thriving more with or without fertilizer? My best friend used to have miracle gro brand before he found out that it was rather killing his plants (he used the brand for years and has recently made a switch).
