One sold, so this is the price for one set. I used this for 4 hours a day for 3 months last winter, starting from seed. It's in very good condition because I used it in an indoor greenhouse. I haven't moved it around, so there are no scratches. Perfect for greenhouses! It's a 250W model with a thermostat! It automatically turns off when the set temperature is reached and turns on when the temperature drops. It saves electricity and is very convenient because it manages the temperature automatically, even if you leave it unattended! I recommend it because it's getting colder! Feel free to comment if you have any questions! I will ship on Saturday. Thank you.
