Free shipping on non-freight orders of $200 or more in the contiguous U.S.
Shipping terms
Pressure regulator for drip tape installations. Regulator is placed on the mainline at the water source where mainline is attached. Works perfectly with the mainline hose connectors that we sell.
Specs: FHT (Female Hose Thread) x MHT (Male Hose Thread)
Inlet pressure max 95 psi, throughput 7.0 gpm
Drip requires max pressure be set to less than 15 psi.
Drip Irrigation
Perfect for tomatoes and cucumbers inside a hoop house, drip can water roots without wetting the plant.
What is your flow rate?
Knowing your flow rate is critical to sizing your system. If you don't know, you can find out by filling a five gallon bucket at the point of connection for your drip irrigation. Time how many seconds it takes to fill the five gallon bucket.
(60 / Seconds to FIll) * 5 = The GPM or gallons per minute of your water source
Example (60 / 15 seconds to fill bucket) * 5 = 20 GPM
Feet of Drip Tape Required?
A 30" wide bed should have 2 to 3 lines of drip tape. For quick absorbing soil, sand, or tightly spaced crops, three rows makes more sense. The rule of thumb is for every 12" of bed width, a line of drip should be added.
Multiply number of beds X drip lines X length of bed
So for a 100' x 30' hoop house with eight rows of 30" beds, the calculation would be
8 beds X 3 drip lines each bed X 100 feet of bed = 2400 feet of drip tape
Drip Tape Water Needs?
How much water flow is Needed?
You would multiply the water needs of the drip tape X feet of drip tape being used
Continuing our example
( 2400 feet of drip taope / 100, the rated length) X 0.6 GPM (8" Spaced Tape)
= 14.4 GPM to irrigate the entire 30 x 100' hoop house
- 8" Spacing Flow for 100' of tape at 10psi is 0.6 GPM.
- 12" Spacing Flow for 100' of tape at 10psi is 0.4 GPM.
If your flow rate is less than the amount needed to irrigate, then the drip tape must be zoned. This means dividing the hoop house into sections that will be irrigated seperately.
Supplies Needed
- Drip tape - total length based on calculation above plus 5% for creating end of lines
- Main line - Enough to use to head the drip tape. This would usually be the width of your hoop house plus the distance to your point of connection
- Drip tape barb fitting - You need one for each line of drip tape
- Filter - If you are on anything other than city water supply
- Pressure regulator - Drip tape requires max pressure be set to 15 psi
- Timer - This will allow daily timed irrigation which is needed inside a hoop house.
- Mainline pipe cutter - makes straight and clean cuts in poly pipe and drip.
- Fittings - Mainline fittings to bring pipe to your water connection to your hydrant and those needed to zone your system. This may include elbows, tees, swivel connections or couplers
