Spikes and layers are areas in your soil that have enriched nutrients.
Today I’m going to amend my 6 gallon planters with fresh compost and some Gaia 4-4-4.
Then I’ll be mixing up some fresh compost, fresh ewc, kelp meal, fish bone meal, coco coir, Gaia power bloom and gypsum. I will use this mixture to make a 3” layer on the bottom of my planter. As well I will have 4, 2” by 8” round holes filled with this mixture that are placed around the planter. These are the spikes.
As the plant matures the roots reach the layers and spikes for that extra nutrient blast.
Along with my 3/4” topdress of fresh ewc at 2 and 4 weeks of flower, the girls are provided with ample nutrients to finish up nicely.
