Dude, let me tell you about this Botanicare Cal-Mag Plus stuff. It’s like, the ultimate munchies for your plants. 🌿 Effectiveness: My plants were looking kinda sad, you know? But after giving them this, they perked up like they just had the best snack ever. It’s like magic, man. Ease of Use: Super easy to use. Just mix it up and water your plants. Even if you’re feeling a bit… relaxed, you can’t mess this up. Value for Money: Totally worth it. A gallon lasts a long time, and the results are totally worth every penny. Packaging: No leaks, no mess. Just pure plant goodness. If your plants need a little pick-me-up, this is the stuff to get. Happy growing! 🌱 ... show more

  • Good stuff but poor shipping
5 star product but poorly shipped and was leaking upon delivery. The box was crushed and the bottle inside was cracked and leaking. Now I need to deal with returning a leaky bottle. Sometimes, for some things, it's better to go visit the local hydro shop!
