I recently bought grow big hydroponic but I am growing in soil. I would exchange it but when I looked at my reciept I realized they did not charge me for it. Does anyone know if I can use it in a soil grow and what the dosage would be?
I would think it should be ok. And I would probably use the same dosage as the soil version (1 teaspoon per gallon). Most of the nutrients I use have both hydro and soil instructions on them. The main difference being that hydro is all about ppm and reservoirs, where soil is about watering every 3-5 days.
You can use that but, the NPK value is about 1/2 the soil fert. I would start off 1/2 strength with all FF nutes and add or cut back depending on how the plants respond during the grow.
