I haven't used Build a Bloom, but I've seen Jeremy use it. He used it as a soil drench. I think that's the safest, most beneficial and most effective method to use it. It has vegan non-gmo soy aminos like what I use alone and with other ingredients. It helps to chelate the micronized minerals and make the phosphorus, potassium and calcium more readily available.I've got Build a Bloom but don't want to use it in the res. Ive got a couple plants started in RS bags ill use it regularly with, but wanted to try it as a foliar feed with the EBjrs
You can apply this to the top 'food bank' of your EarthBoxes. The easiest and safest(trying to keep nutes out of the rez) way to add, is to make a wet slurry of compost with Build a Bloom water mixture and apply the slurry on top of your food bank. I use this method when applying my homemade J. Best time to apply is when the rez is empty and a short dry time. I usually apply EWC first and the slurry on top of that.
This keeps the 'engine' of the EarthBox going with biological activity. Foliar feeding has its place. I just saw a difference in your girls. That's why I asked questions.
