Drip system experience assistance please.

So I have 180 plants in my flower room.

I have a 300 gallon reservoir to be fitted with an automatic shut off, this reservoir
will be atop of a very sturdy cabinet. Within the cabinet will be (4) 55 gallon barrels.
The reservoir will house only RO water and will release water into the barrels when I
need to mix fertilizers. Barrels are easily removable for cleaning between fertilizing.

The cabinet will be conveniently located at the end of my rows. I have 4 rows of plants
with 45 plants in each row. Basically i would like for this drip system to be able to
last a full 48 hours per fert mix, giving each plant just over 1/2 gallon of water per
day at max. I am also trying to keep my run-off to a minimum.

My main question.

I've been looking at several different emitters. Just wondering which have shown to have nice even dispersal and won't just allow the water to pool at the base of the plant.

Thanks for the help.

nice set-up. i have had success using drip stakes and opening up the flow valve all of the way - 2 per plant. You will have to move the stakes every week or so to prevent pooling/erosion.

soaker hoses! they emit water all along the hose, so you could wrap the base of the plant with the hose... go to home depot and look at all the emitters, they are many different kinds... they come in different flows too like 1 gallon per hour, 2gph, 3, all the way up the 4 gph... so you could go with one 4gph emitter, two 2 gph emitters, or four 1 gph emitters... whatever you want to spread the water out over the root zone... if you have a total of 4gph emitters, then you would only have your pump on for 7.5 minutes for each plant to recieve .5 gallon (approx.)

i run my drip system without emitters and make every spaghetti line the same length so each plant gets the same amount of water (a lot)... However there is a ton of runoff, but since it recirculates the plant drinks the amount of water/nutes it needs during the time the pump is on and then the rest goes back to the tank... a problem you may encounter is during the life cycles of the plants is they are going to all require different amounts of water...
