.... and that other one is the upgraded Vivsun AeroLight with the fan in it. I bought this on the recommendation of Jordan Mara of the YouTube Channel 'Mind and Soil'. Jordan tested 5 different grow lights from $15 grow lights to a professional quality light that was nearly twice the price of the Vivosun VS1000. The Vivosun came out on top for the sturdiness and quality of the seedlings. Take note though that this light can provide enough light in the correct wavelengths to grow right up to flowering of fruiting. I Planted my seeds a week ago and the plants are just showing. I set mine up yesterday hanging below a clothes dryer frame, over two seedling trays. It comes with a hanging bar and two very clever height adjustment clips. Press the button to lower, pull the cord to raise. There is a rotary dial for light intensity, 25%, 50%, 75%, and off OFF. The light units can be linked together on a network and they can be operated by a controller. Mine is a single light on a manual timer set for 15 hours of light per day. It is BRIGHT, just like sunlight, and the true colour of a sunny day! My seedlings are looking good and not drawing to the window as they have in previous years. I think it is a great light and will improve my plants. Incidentally, the fan in the upgraded Vivosun light provides 'breeze stimulation' which strengthens the stems. I am very pleased with it. Check out the experiment on the Mind and Soil YouTube channel.
