It better be recirculating or you’ll be running bucket changes non stop. What size space are you dealing with? If it’s just a 5x5 or so then plant count is irrelevant you need to focus on canopy size and just fill that space.
Pros: Great root development, Fast Veg, good yield, simple and effective flush
Cons: if temp or pH are off for any length of time, you will lose the entire unit, takes several runs to get dialed in, more organics=more issues, humidity
Keys: Chillers, recirculating system(Current Culture or DIY copycat), CHILLERS, enzymatic, nutes/ppm/EC, quality chillers and temp control in area where they are stationed.
