Reliable and efficient!
I have been using this heater for about 5 months now with no issues. It's reliable and seems durable, it achieves the target temperature with ease. Heater settings are also pretty straightforward. Bought it on sale so it was a great value.

Great heater for the price.
This heater is really great. It's a little noisy, but it's nowhere near annoying. It keeps my grow tent at the perfect temperature, and I can just set it and forget it pretty much. Overall, not a bad price for it either. Very impressed.

Poor heat control
Hard to operate. followed the instructions When heat is operating it does not put out the output of heat that is desired in my greenhouse. Doesn't get hot enough to cover a 7x10 greenhouse. Then they refuse to refund me my money because it passed the date 30 day mark which I bought it in the summer and didn't have to use it until the winter came now that the winter is here I found out that it does not work up to their specification.

good choice for smaller grow spaces
I’ve used the Spider Farmer Space Heater in my grow tent for a few weeks now, and overall, I’m very impressed! It’s compact, efficient, and really does a great job maintaining the temperature in my tent. The heater is pretty quiet too. the only reason I’m giving it 4 stars instead of 5 is that I wish the instructions were a little more thorough when it comes to setting up the temperature ranges and it had a slightly larger coverage area. It works great for smaller tents, but I could see it struggling a bit with bigger setups especially if you live in a colder climate area. I have my grow tent located in my garage and I am located in the southern part of the U.S. where we maybe get 1 week of cold temperatures which falls in the teens and it held up nicely. Still, for most grow tents, it’s an excellent choice! Highly recommend this if you need a reliable and cost-effective heater for your grow tent.

Great heater multi function and solid build!🤗👊
Just got the Spider Farmer heater, and I’m already impressed. Setup was a breeze—just plug it in and go. It’s easy to use, puts out solid heat, and the best part is how versatile it is. This thing isn’t just for heating a grow tent—you can use it to dry your harvest, warm up a room, dry your shoes, or even bring in fresh air. It’s a multi-function heater that’s perfect for growers and beyond. Definitely a solid addition to any setup!

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

Had to replace the plug top for a uk as it was supplied with a US plug, it's dual voltage despite the heater not displaying this info on the heater but the manual does confirm it. They have used a flex which doesn't indicate too easily which side is the Live or Hot as our US friends know it but a quick Google search helped me identify the conductors polarity enabling me to wire the UK plug. After this I simply plugged it in, connected to the ggs controller and it just started to run to environment settings I had already pre set. Very happy with it :) Delivery was about a week which is good considering it's journey

Brilliant item, got it just in time to stop the cold from creeping in. Highly recommend this item and many other spider farmer items too. Very easy to set up and fit, brilliant quality

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.

You'd think this thing can heat up at 2'x4' grow tent past ambient of room it is in, but you'd be wrong. Rearranged inflow/outflow in tent, but nope. Set GGS controller to have 1 degree deadband, again nope. 65F plus mats was great for germination, but not so much for my seedlings. What a waste of my money.
