I am hoping that three rows instead of two will not make it too difficult.. I was planning on running 8mm white tubing down to a T splitter over each row of 3 plants then running 3mm tubing Down to a 4 way splitter then a Y splitter at each plant with 2 carrots per pot.. Thing is the distance from the 4 way splitter will be longer for the outside row of plants.. Will this be too long a distance for 3mm tubing? Should I only use 1 carrot per pot with drippers? It is to be a gravity fed system and I noticed that they sell different kits for gravity fed systems so is that what I need? What's the difference? I don't think they supply a pressure reducer in the gravity fed kits but they do recommended using them in gravity fed systems so do I need a pressure reducer? What size rez would you guys recommend? How high Do I need to keep it? They recommend 3 feet apparently.. Is that above the ground or above plant level? Will it be OK to run the line into the inlet hole In the tent which seems very low and is on one side of the tent (not in the middle) or do I need to add another hole in the middle & higher in the tent? Thank you
In regards to your blumat questions:
Best to run the 8mm tubing across the top of each row of plants, or on the floor of the tent. Each blumat carrot comes with a 8mm to 3mm tee, so you can just add them next to each pot. One carrot will be fine for each 5 gallon pot, but I recommend three distribution drippers.
You do not need the pressure reducer when using a gravity system of this size.
The rule of thumb for res height is one vertical foot above the soil level, for every 10 horizontal feet you wish to travel, so three feet would be fine. Also, it is ok to run the tubing through the hole on the floor. There will be enough pressure to bring the water up to the soil level surface.
You could get away with a small 5 gallon res if you put a float valve on it, or are willing to check it every day. But I would want to use something larger, at least 20 gallons.
