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

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.

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.

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.

Very effective and easy to set up.

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.

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.

I bought it for my greenhouse for outdoors for the winter. It works great ONCE you figure out how to use it

Did have a hiccup with the delivery (not thier fault but they made it right anyway) not to mention that the item is perfect for my needs and it already seems to be working after a hour I'm happy as a lark

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.
