Oh btw for those that use liquid nutes I have a question. The directions says I only need 2 tsp per gallon so I was wondering if it was alright if I just bought a gallon of water and just add 2 tsp to that gallon and just keep it in the room and use that jug when ever the plants needed feeding? I don't know if the nutes will still have the same effect if it has been sitting in the water for like a week or so. Any feedback?
