I use cool whites for maximum light and warm whites to induce blooming.The bulbs touted as "greenhouse" lights rarely are any better than cool whites.These days there are lower wattages available for florescent fixtures,which put out almost as much light as the previous higher wattage tubes. For example, 32 watt replacing a forty watt.That efficiency costs less money. The led lighting market is filled with snake oil and wild, wild west atmosphere. A few stable corporations are standing behind products,still made in China,at low cost,which they are greatly overcharging for.Most are either direct marketed from China or by small local entrepreneurs and vary widely in honesty in marketing,quality,detailed capability information(specifications),and actual plant growing applicability. There is a new family of leds on the horizon which are greatly more efficient. They use a non silicon base.even better and farther in the future are leds made using a carbon base ((OLEDs).I'm waiting.Unless the disposal costs of fluorescents start making them cost prohibitive, I am sticking with cool whites for now.

They do appear to be collecting dust...although it doesn't look "dirty" per se. Not sure if that makes sense, but it is more white in color than "grey". But I can tell a big difference from a new one to the old one. The LED is flashing, but I would have to look at it again after to know the sequence. The furnace shuts off after a period of time because it is not blowing properly..... before it was because the blower motor was locked up, now it seems to be due to the filter being too clogged. The new blower motor is the exact same, yes

I'm shocked! I thought you were a natural blonde!

You would be much better off with a sloped drain board with raised runnels in it running into the sink than with carved in runnels. I posted a pic of mine on the last runnel thread if you want to see a drainboard in a counter. Much less possibility of standing water which is the enemy of any wood.
