What up grow community! I'm looking for some help brainstorming a solution to using 2 buckets (1 nutes, 1 silica/calmag) with a single 1/2 inch feeder tube. Currently I have a pump taking my nute mix out of a 10 gallon bucket and filling my 1/2 inch feeder tube that is running the top lip of the flood tray with twelve 1/4 inch drip lines ported off of that. How would I go about adding a 2nd water source to the same tray without: running a 2nd feeder tube around the lip, moving the tube from pump to pump, or using manual stoppers that I switch back and forth daily to supply the alternating feedings. Any help is greatly appreciated. Thank you!
