Flexibility is a key virtue of drip irrigation. My wife likes to move stuff around a lot - I tried to get her to plant things in pots and put the pots on pallets so I could just move them around, but she got all puffed up... To your point, you can use goof plugs or just replace the pipe past the filter and pressure reducer......pipe is about a dime a foot, so it's not a big deal to replace once a year. I would rather replace than repair. Home Depot has fair (but reduced) inventory of DIG drip irrigation supplies.

I don't really understand what you are asking, and am not clear on what you mean by 'breadboards'. You're right, you can buy all kinds of LEDs... beads or diodes, diodes mounted to aluminum stars or squares, cob beads (chips on board), square/rectangular arrays, along with a vast array of different wattages, light intensity outputs, and spectrum options. You mention "lots of experience soldering electronics", which will definitely come in handy with DIY LED projects. It is very important to always consider the thermal management (heat dissipation) aspect when working with high intensity LEDs. Most DIYers use a heat sink to attach their arrays. Although, even a heatsink is not enough to passively cool some LEDs, so cooling fans are also incorporated into the fixture design. If wiring in series, make sure you calculate the forward voltage & amperage properly. Most use constant current drivers to power their LEDs (arrays and/or strings). And I would venture a guess that most 3-10w LEDs could be powered with as little as 350ma, up to 700-1,000ma with ease. Some LED producers (e.g., Cree) are currently manufacturing chips/diodes that are very efficient and very intense. A lot of today's LEDs offer a good variety of kelvin temperatures and spectrum choices. If you do a goggle search for DIY LED supplies, I'm sure you can find several suppliers that can meet your needs for a 'killer' DIY project. I would list a couple of good ones, but I think this site kind of views that kind of thing as a form of advertisement. Late note: got it now, just goggled LED breadboard! I've never used a breadboard for any of my DIY LED projects, so I really cannot offer any suggestions. I believe breadboards are being used a lot for the smaller indicator type of LEDs and 'arduino' (for fading LEDs and other possibilities)? I've always used high intensity LEDs mounted on various types of heat sinks, along with manually soldering any wiring for my DIY builds. If I comprehend this right, bread boards require no solder, correct? I guess my main concern with breadboards would be how to go about mounting several high wattage/high output LEDs and how to manage heat, with a large enough size breadboard to make a decent size grow light fixture.

If you are still searching for a 3000K LED lighting option let us know! All of our Warm White Flexible Strips we would recommend for Under Cabinet Lighting are 3000K and can be hardwired/dimmed! We ship the same or following business day, and offer free design services! Please let us know if you have any further questions!

I'd use tape lights for the upper cabinets. I'd also put lights on top of the cabinets that stick up to provide light without the shadows that you see now. You could wire the tape light sections together sequentially or connect each section to a terminal block (example). A driver (example) is needed to power the 12- or 24-volt tape lights but you'll have plenty of space to place one on top of the cabinets. You could run wires inside or behind cabinets to their undersides (i.e., above the counter). You could put tape lights there in channels with diffusers (example) to reduce reflection of the individual LEDs in the countertop. Be sure to use a dimmable driver and use a compatible wall dimmer to control the lights.
