Correspondence with SureToGrow regarding feeding schedule. My questions to them:
I have an Ebb & gro hydro system. I was interested your product and decided to try it out. I currently have some plants in that just started their bloom phase. The plants were grown in 4x4x4 rockwool cubes for 4 weeks of vegetative growth and then inserted into the Ebb & Gro buckets. I have half in STG Storm Typhoon media and the other half in Hydroton. In doing more reading about your product it appears that STG may require more frequent watering than hydroton. Is that true? Do you have a recommended feeding schedule for the STB Storm Typhoon product? Currently I am watering for 15 mins twice a day during lights on. Also, do you have the percentages of substrate porosity and air space for STG?
Their response:
Twice a day when the lights are on should be sufficient you may cut back to one depending where you are at in your bloom cycle now. If you are more than half way through bloom once should be enough. The air to water ratio of STG is 18/82 when saturated. I hope this helps.
