Im about to start growing using homemade ebb and flow. I new to this so i need some advice. I heard you need to sterlize all this equipment tub, pump, etc. What should i use and for how long. My seeds are about to pop so i need to get started on this asap. Is there anything from hd lowes, or anyplace that i can get the stuff to start. Sorry i have just been reading but not sure. Im using rockwool, clay pellet, any tips.
