Spider Farmer Grow Tent Heater,530W Portable Heater with Smart Temperature Control, 4 Modes & 24H Timer, 10-Level PTC Heating & Extension Hose for Plant Rooms,Greenhouse, and Grow Tents

This heater works well for the size. Shipping was pretty quick. You do have to crank up the heat level to warm up the space in a matter of minutes. Overall it was easy to install. i had heat working in a matter of minutes.

My banana plants are toasty warm. Keeping them at the day and night temps I need. I will be a happy camper if I get them to bloom

Works great to keep the temperature well above freezing at night but not too hot during the day. Great value for the money and saved my plants.

This was an actual lifesaver, not only was it compact that it can fit in my grill room, but it pushes a lot of heat, especially for a large groom. Space that I have being that it’s winter time this heater kept my tent at optimal temperatures. It was great because with the censor, it turned off once you reached that point.

Does not maintain steady temperature. It offers several modes, but it isn't clear which mode it's in (manual doesn't explain how to know), and even with all modes set to the same temp (night, day, all-time), my grow tent has fluctuated as much as 14 degrees (even though I set the tolerance to +/1 2 degrees) throughout a day. I contacted the manufacturer directly for help and their excuse was that the grow lights are affecting the temperature in the tent, causing the fluctuation. Of course the grow lights make it warmer, but the whole point of purchasing this heater was because it has a thermostat, regulating it's heat output based on the temperature in the tent!! Overall, very unhappy with the product and the service. I will be returning it for a different brand. Now I am just hoping that my little seedlings don't get too traumatized by the constant back and forth. I went to check the temp this morning and it was 58 degrees in there, despite the heater being set to 70! Don't buy this heater unless you want to have to constantly monitor it.
