I have used this system for 5 or 6 years, and it works pretty well. My plants are kept moist all the time and any extra water drips down into a sump tank and gets pumped back to the plants. It's all on a timer, that has 15 minute on off settings. The first part is the timer. Because if you...

I put a russet potato in a clear plastic container with a dish of water. It had sprouted potato tubers(I think that's the right term) but I waited too long... it now has roots and white fur. Is there a reasonable change I can still get a plant out of it, or should I just start over?

In Bernoulli's equation, you have static, dynamic, and hydrostatic pressures equal to a constant. In one sense, I'm wondering if the dynamic part of the equation explains this since -> Pressure = (1/2*rho*velocity^2) and pressure can be expressed as a force / unit area, therefore, an increase in...

Hi everyone, hoping for some quick help. I’m trying to get the chemistry right for an aquaponics garden I’m building. I screwed up pretty bad the first time and just swapped out almost 100% of the water (there was a residual 2-3 gallons in the bottom of the growbed). Last night added in about...

I have looked all over the net and can only find descriptions of how to use a dividing head, followed by countless numerical examples. There must be someone on PF who can give a short algebraic description of the way they work. Machinists as a whole, don't seem to want to present the topic in a...

I have tried this a couple of times but no successBefore you buy materials, you need to work out how much you will need. As such, you need to calculate the following: the circumference of the pond -A the perimeter of the garden the patio area -b the lawn area (minus pond area) the pond area- a...

What I did: x = Emily's garden's width x+4 = Emily's garden's length y= Sarah's garden's width 18 = Sarah's garden's length y=x+4(as stated in problem) x/x+4 = y/18(as the two gardens are similar) Which means that x/x+4 = x+4/18 Now I can't seem to find x

Here's another question I'm finding it hard to get started on: " A garden is in the shape of a rectangle, 20 metres by 8 metres. Around the outside is a border of uniform width, and in the middle is a square pond. The width of the border is the same as the width of the pond. The size of the...

Hello, More seriously, my grandmother does not have this in her garden. I am looking to know what it's imply if normal citizens were to get hold of little quantities of these. I am an interaction designer who needs to understand a few things about nuclear physics in order to validate some idea...

Hello, I am confused why when we turn on a faucet on small, the water doesn't accelerate out of the tap like you would expect from Bernoulli's equation where a reduced area means a high velocity. It seem's like the faucet only regulates flow rate but not the pressure. However, if you connect a...

I'm planning on starting a salsa garden to make fresh salsa this year. My garden has nine 4'x4' beds and is located in Virginia. I know we have some people on this forum that do this and was wondering if anybody had any suggestions on what to put in it and how many of each plant to grow. Also...

There's already a thread on conventional (terrestrial/earthen) gardens, so I thought I'd start on water gardens. I was visiting a local nursery last week, and they have a really water garden set up (about 2 m x 3-4 m) in the shape of an irregular oval. Anyway, some members have posted...

I found this problem in Erwin Brecher's "Journey through Puzzleland" and I find it baffling. There is a garden 55 yards by 40 yards. There is a diagonal path through the garden 1 yard wide. How long is the path? Notice that it is not quite a 40-55-11-root-185 diagonal because ALTERNATE "corners"...
