I got it at a hydro store but I have seen it at Home depot or you can order it on amazon. When I use it I don't measure it lol. I just grab a 5 gallon bucket and pour a splash of both in it. Don't worry about it being too much cause you are diluting it with lots of water.
I use this
with
you don't need to use the recharge. I just use it if I'm lazy to making organic compost tea for my plants/trees.
I don't grow lettuce or spinach. Everything up in the pics i provided, I use for my thai basil, coriander, mint, vietnamese mint, cuban oregano, peppers, etc..I just dilute the bloom or grow with a little more water cause I think the recommendation might be a little too strong for the herbs.
For herbs I only use flora grow
For fruits I use both flora grow and bloom
But I also give my plants chicken manure, potassium, and dry up egg shells. Worm casting is important too.....in a pot or in a raised bed
Have you heard of comfrey tea fertilizer?
that stuff is the best for plants but literally smells like poop...It smells terrible but damn the plants/trees love it and my neighbors hate me.
