SPIDER FARMER SF-600 LED Grow Light 2x4 ft Coverage Sunlike Full Spectrum Plant Growing Lamp for Indoor Plants Hydroponics Seeding Veg Flower Energy Saving & High Efficiency Grow Lights 384 Diodes

This is the second of these units I've gotten. My plants seem to like them & are thriving better than with the fluorescent T5s I had before. Using in unheated Costco greenhouse to grow winter salad greens, start seedlings, keep tender perennials going. So far so good!

My tomato plants are averaging 2-3 inches of upper growth every day since using these grow lights. They exceeded my expectations. I had to buy extra pulley systems to raise and lower these lights as the supplied mechanism was too awkward and too short for my tomato plants. Due to their ability to grow the plants rapidly, it became a hassle adjusting the lights upward every day. I would suggest Spider Farmer use a simple light chain and S hooks system to improve the versatility but the lights themselves are fantastic. They've been running for approximately a month now, 16 hours daily with no issues. The cost of the lights was surprisingly low for their high performance!

spider farmer sf600 works great for desert rose propagation ,very bright

I have both models the 600 and the 300 as you can see in the pictures. They are basically the same, just double everything. I have used their larger lights for tents and was very happy with them. When a head of lettuce hit $5.00 I figured it was time to see how their lights are for Veggies. For results I could not be happier. In one pic you can see the "spill over" light is enough to grow my potatoes and start my tomatoes. I changed setup once I realized it works and we actually use it. It's exciting to grow and eat your own food. The reason for only 4 stars is that the 1st one I ordered the power brick died the 2nd time I plugged it in and I can see a possible issue in the future because it's not the strongest connect between the plug and the light board. Think loose USB or headphone connection on your laptop - not the strongest connection and they can come loose. Now these should last as they really shouldn't be plugged and unplugged that often at all... just stating its not the most solid feeling light I've handled. That being said I went ahead and purchased the more expensive 600 version even with my own concerns. The customer service was fast with response and solutions to my previous issue and I really love their price vs performance compared to other companies. With them you also know you are getting the higher grade LEDS and Driver. I believe the pictures will show more than I can write.
