Journal October 28, 2012

Today I planted two batches of romaine lettuce in system number four, the varieties are: Little Caesar, and baby romaine.

This will probably be the last time that I use fluorescent lighting for growing. At some time in the near future all of my growing will be under LED lighting.

The driving factor in the replacement of fluorescent lighting with LED lighting is the cost of fluorescent tubes. My existing fluorescent fixture has six tubes, and the cost to replace the tubes annually is almost $100. On the other hand, LED lights can last up to 10 full years.

Recently I purchased a new LED grow light that I will use in my grow chamber to replace the large fluorescent fixture. When this light is installed the grow chamber will have: a six band flower series LED, a 90 W red/blue LED, and the new light.

The new light has 50 3 W LEDs with the spectrum being: red, yellow, orange, blue, white, green, UV, IR.

In addition to being more cost-effective in terms of replacement, the LED lighting will also lower my energy cost.

What light did you get?

I needed a small light to cover about 3 square feet so I bought this one:

I have four of their lights and they are reliable and perform very well.

Thanks, Do you still use the old UFO light?

I am In the process of redoing a grow chamber very similar to yours and only have one ufo light with the rest fluorescents. I would like to go all LED if the price is right.

I only grow in the basement in the middle of winter when it is to cold in my unheated sunrporch.

Absolutely! The UFOs are being used for carnations right now. And, they work very well for germinating large batches of seedlings. I feel that they will cover about nine square feet, if you are growing lettuce. or other greens. My original UFOs are still working very well and I am glad that I have them.

Good to know. I have only used mine to grow dakon radishes last winter. I would like to try and grow a black cherry tomato cutting to frutation this winter in the chamber. ( and a cucumber that is struggling on the sunporch due to the cold)

I try to keep a few tomato cuttings just growing through the winter to take cuttings for spring planting.

I see the UFOs on ebay are still a good price so I might just pick up another.
