Your pump is not pumping the water. check your fuses to see if you have a blown fuse. Your may have to replace the pump if all the fuses are good. -Also,check the routing lines from the reservoir to the pump and to the sprayers to see that they are in working order.
It is best to take a spray bottle full of distilled water (because the chlorine in tap water will kill them) and just spray the container or soil until it looks moist. How many times a week depends on the size of the pot or container.

70 ml if it is full.
1/3
Rather than filling the container completely with water then emptying it, filling it 1/3 full, shaking it and emptying it 3 times will result in a cleaner container.
pour water into it until full, then pour that water into a measuring cup.
Irregular objects can be volumetrically measured with three simple tools; a scale, a container large enough to contain the entire object, and enough water to fill the container. If you fill the container with water and weigh it, fully submerge the object in the water and remove it, compare the final mass of the container and water to the container full of water, the difference between the two in grams is the same as the volume of the object in cubic centimeters.
Assuming the container is full at 1500 liters, the container's volume in cubic feet will be about 53 cubic feet (52.9720005, more precisely).
if your melting wax in a glass container be sure you do so at 125 degrees. get a deep metal pan, fill half full with water, heat the water, put your wax in your glass container and put the container in the pan,WATCH IT CLOSELY.
Coolant container will say if it is pre-mixed or full strength. If full strenght, mix it 50/50 with water. Pre-mixed coolant can be added "as-is"
A hole.
1/2 distilled water 1/2 antifreeze to the full line in the overflow container.
