Automatic irrigation
Rabidrejectstarted grow question 3 years ago
I bought a dustbin with a lid as bought a water pump, tubing, 4mm connectors and 4mm plastic sprayers that are meant to be controllable by screwing a lid.
It’s not all 4mm tubing. The flow is so weak and I can’t figure out why. The pump has a big enough flow. What a let down :(

die schläuche dürfen keine windungen nach unten oder oben haben. die pumpe ist sicher nicht stark genug um zb. 50cm unter den tröpfern das wasser raufzusaugen... stellst du den wassertank jedoch höhenmäßig über die tröpfer in den töpfen wirst du feststellen, dass der wassertank, auch wenn die pumpe aus ist, kompett leergesaugt wird (saughebereffekt) - kann man mit einem rückschlagventil jedoch verhindern. Alternative: wasserspiegel im tank ist auf ca. der der tröpfer und du nutzt direkt an der oberfläche einen T-Splitter, der ca an der waseroberfläche des tanks platziert ist und #1 schlauch zu den tröpfern, #2 schlauch ganz kurz halten und in den tank zurückrinnen lassen (verhindert dann den saughebereffekt ganz sicher). Weitere Alternative: Pumpe kaufen, die auch tatsächlich die pumpe mechanisch schließt - somit kann kein wasser mehr nachlaufen...
hatte genau das selbe problem und habe es dann so gelöst

bummer ....
my 5cents ...
maybe you have an airlock ... try bleeding the air from the line - open the furthest end and let the liquid flow out freely. then plug it and try again.
depending on the scale .. you may need an air relief valve ....
also, try rigging it with a manifold without the nozzles and see if it is any better ... then you can just adjust (reduce) the irrigation time
good luck

The tube diameter sounds fine, is the pump connected to constant pressure? Or is it a submersible pump? Is there any one way valves in the plumbing? I know with submersible pumps wont pump well if its getting air

The problem in plants when I supplying CO2Hello! After adding CO2, I noticed problems on the leaves of my plants. Grow in coco+perlite, water with 1100ppm solution, 1000ppm co2 in air. Drain from the right 1400ppm and 1800 from the right. Is it related to co2 and irrigation system?
