Yes it does Cath, you will find black corrugated 1¼" diameter, sump pump hose, that has a wall thickness of about 1/16". Black, re-enforced, corrugated pond hose, that comes in various diameters, has a wall thickness of about 3/16". The sump pump hose will collapse very easily with the weight of a waterfall rock on it. Whereas the other thicker walled type will not. Of course there is a great difference in the cost. Black hose is preferable to that of clear hose, to limit the build up of algae on the inside of the hose, caused by sunlight. "Horton"

RG, Thanks for the info. Aloha

I know you need to replace the tubes every saeson to start the vegetables Not necessarily, but probably. Post exactly what ballast or shoplight you have and the exact make and model of tube. Then we'll let you know whether you need to throw it away. A 20% light decrease would not be noticeable to your eyes but is significant to a plant. You'd be able to see the difference side by side with a new tube but not to the extent that you'd throw your hands up in horror. The light output of all plant lights decreases the longer they are run, also each time they are switched. Historically, as in 20 years ago, every single light lost so much light that it was more cost effective to buy new bulbs or tubes every 6 months than to run old lamps putting out less light. This is no longer true. Modern triphosphor fluorescents (but not the $1 tubes from China) running on electronic ballasts lose about 5% of their output even after 20,000 hours operation, so run them to failure which will be several years even running every day. Cheaper tubes, specialist tubes (wide spectrum, plant spectrum, actinics, etc.), compact fluorescents (the more compact, the worse), and anything on a magnetic ballast still loses a lot of light and should be replaced frequently. The best pulse start metal halides on exactly the right electronic ballast lose about 10% of their light output. Again, not worth throwing them away every 6 months. Probe start (ie. anything that doesn't say pulse start) bulbs and most bulbs on magnetic ballasts still lose enough light to need frequent replacement, and many metal halide systems still sold today are so horrible that you absolutely need to replace them every 6 months. HPS bulbs still lose something like 20% of their output relatively quickly. You should probably replace them every few thousand hours, but check exact specs on any bulb and ballast you have since I haven't looked at the latest data in detail. Lights which have been stored in sensible conditions will keep for years without problems. Excessive temperature variations can cause them to degrade.

Finally a question I can answer. The program PSP was sold by Jasc to Corel, therefore a new name. Try opening PSPX, click on Toolbar and scroll to Tools and make sure there is a check there, to show the toolbar. All the tools should show up down the left side of the program including the drawing tool, which I believe is third from the bottom, and looks like a pen nib. There are drop down arrows beside some of the tools, click to see what they are. You must have an image open for the tools to be active. Hope this helps you - new versions are always a pain until you find your way around. Personally, I never quite make it before the next version comes out! Elaine
