    • Jon,

      Been my experience that Roundup and broad leaf weed killers will not harm Moss.

      Here in Oregon every store in the country sells special Moss killer liquids and powders and they work , sort of.

      Spray a test area and wait a couple weeks, if no burn or other harm your'e good to go.

    • Spectricide has a product called Weed Killer for Lawns. We've used it in flower beds to kill clover and other weeds with no harm to the flowers or shrubs, mostly groundcovers where the clover is coming up through it.

    • I wonder if there are some chemicals I could use that might make it easier. I've never tried Preen. It would be fine in the gardens, but I wonder if it will work in the moss areas without killing it.  A lawn weed-and-feed would take care of the clover and broad-leaf, but again, not sure what it will do to moss.

       

      Now I can get back to extending the lighting project and repairing some more structures.


      Jon- in my experience, lawn type weed and feed does not usually kill off clover. I've had success using a product from Ortho that is made specifically for clover. You mix it up with water in a pump up sprayer. If you have a lot of clover, it might take two applications to kill it all. If you are trying to kill weeds that are mixed in with your moss or other plants and trying not to kill the moss, you could try a broadband killer (grass and weed killer), like Round Up (I use Spectrum 'cause it's cheaper and I'm cheap). The trick is to saturate a paper towel with it and wipe it on to the leaves of the weeds that you want to kill. This method offers you more control than spraying it on. I should mention that it may still affect the moss because the poison that you wipe on to the weeds will work it's way in to the root system of the weeds. If the weed roots are in contact with the moss..... well, things could happen. Your mileage may vary. Oh, and Preen is a pre-emergent. So you must apply before weeds start growing. If you've already got weeds, it will not kill them. It will only prevent new weeds from germinating. Hope this helps. -Kevin.

    • Just spent 6 hours over the last two evenings on my belly in the front yard weeding. My neighbors think I'm nuts pulling grass, clover and broad leaf out of the moss I panted around the railroad. Wet spring and early summer really gave them a boost - I couldn't even tell the moss and real plants were there

      John or Kevin, where on facebook is Kevin's lighting project. I would like to check it out. Thanks, Pete

      Kevin's photos are on his "wall"; posted on June 20.  This is a link to one; but you may need to be a "freind" of Kevin to see them..

    • Chris, thanks for the tip. I'll archive the info for the future.

    • Cliff,

       

      The dealer is VERY REPUTABLE too.  Still a good personal relationship type of guy.

      Cliff the only part you are off is: "10' of this tape would be 7.5mA" , I'm pretty sure that everyone assumed you meant 10 INCHES, not 10 FOOT.

       

      Thanks Greg, good points. However, the 11.5" (the "nominal" 1' length; my tape is cuttable at ~2.9" increments) length drew .75mA. Hence, ~10' would be 7.5.

       

      At least, I thought it would be linear. So I just measured a full roll (~16') of warm white at 9v off a dc power supply, but it pulled only 5.8mA (at 9.1v). Go figure. But then I hooked it up to a new 9v battery, and got only 0.55mA (at 8.2v)! Maybe the battery can't discharge fast enough for higher demands? 

       

      Here's the battery test,

       

       

      Here's the test running off the power supply.

       

       

      You can see that the battery-supplied method is quite a lot dimmer. But, that's 16' of tape, so maybe shorter lengths will be brighter. Also, since it's puller much lower amperage, I'd think the battery would last that much longer. 

       

      Chris, those look like reputable products. Here's the el cheapo stuff I've been using,

      Thanks Cliff. I was hoping someone could figure it out. Sounds like a 9 volt battery will work fine as I usually run my passenger trains two or three hours in the evening. I've had problems with Aristo's pickups on the streamliners off the track, shorting out the track and shutting down the power supply. I'm moving to battery for some of my engines, including eventually my ABA F-7's, so apparently my thinking about changing out the lighting in the streamliners will work. Thank you again for your information.

      When I converted my Aristocraft C-16 to bats, I discovered that one of the tender trucks was wired backwards.

       

      I think they face all the tangs one way to wire them and some get turned around when installed. Only shows up on trucks with wired pick-ups.

    • If you are using LED tape, check this place out.  Much cheaper than MicroMark

    • My experience with this "LED tapes" is that 9 volts is not much difference in brightness from the rated 12 volts.

       

      Cliff the only part you are off is: "10' of this tape would be 7.5mA" , I'm pretty sure that everyone assumed you meant 10 INCHES, not 10 FOOT.

       

      I'd say your estimates are pretty good. Found some people that measured this and got 10ma for about 50 hours. I think these were Duracells.

       

      Now, the internal cell voltages will drop to about 1.25 volts at 50% discharged, so you will be at 7.5 volts at 50% discharge, which might not light off the LEDs.

       

      So factoring the voltage drop, your estimate of 33 hours seems pretty right on, since 50 hours probably will be too low in voltage to fire the LEDs.

    • Rich, I'm glad you asked, since I've been wondering about it as well. And at the risk of derailing John's thread (but hoping to add some data points to it), I did a quick test on a 11.5" long piece of "warm white" tape. This will be different from whatever MM sells, but hopefully it's similar.

       

      A 1' nominal length draws ~.75mA @~9V. It was bright enough to start to bring on a headache.

       

       

      9v batteries vary on mAH rating, but let's say they're 250. 10' of this tape would be 7.5mA, so hours would be  33. If you get LiOn rechargeables, they're at 600mAH, so 80 hours. 

       

      Your mileage WILL vary...

       

      Greg, am I off here? If so, I sure hope it's not by more than one decimal place... 

       

      Cliff 

       

      PS: the illumination still looked great at 7V. But down around 5.5 to 6V, it cuts out.

    • Cliff, that might be helpful. I just purchased a roll of leds from MicroMark and want to use 8-12" segments in passenger cars powered with a 9 volt battery in lieu of track power. From your experience would a 9 volt supply be adequate or do I need to consider an alternative plan? I plan to use the remainder in structures with a conventional D.C. power supply. Thanks.

      Nice railroad Dan. I'm envious of your Kansas green. One of the reasons I went elevated. Tired of the dirt and weeds. Looks great.

      Thanks for the complement. But the green is definitely Kansas, not any skill of mine. You could grow anything here without even trying. Heck, if I didn't pull seedlings out of the layout and have the lawn mowed regularly, the big tree in the yard would create a mini-forest in a couple of years. It's hard to prevent things from growing: I have to work hard to keep ahead of the weeds, grass, and even the spread of plants that I actually want to grow. All that alyssum was self-seeded from last year's planting and it's taking over. Last week I looked out and noticed that the gazebo was completely covered :-) You can sort of see the roof (dark gray) in the lower right of the photo.
