Spider FarmerGrow 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

Fantastic heater id recommendedbuying, also it be awesome if it had a remote & or a secondary/portable display options screen with it be very handy an ideal for operating usage

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.

Will heat a 5x5. Did not have this result with a competitors product that cost nearly double. Cool features for day or night settings. Also can maintain a constant 24 hours. Time will tell on durability. Happy so far.

The media could not be loaded. I was looking for a heater for my grow tent since it is really cold in my basement in the winter time. I have other Spider Farm products, decided to give this heater a try. Set up is really easy you screw on the vent tube and plug in the sensor and you are ready to set up the heater to your need. There is a bunch of different settings you can configure for you personal set up. I have it set to day time 75 and night time 70 for now you can clearly tell on the graph when I started to use the heater (see picture). Didn't want to shock my plants too much at first. I will eventually change it to 80 during the day and 70 at night. I like how there are many different heating options you can set up with the heater. Now I just have to give it some more time to see I any issues with the heater. I will update this review if I do encounter any issues. As for now I'm happy.

The media could not be loaded. 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!

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.

This is very difficult to set up for using at higher temperatures, the highest i got it was 86 degrees and it automatically turns itself off without no timer running after about an hour? I set the temperature at 100 and it stays at the same temp of 86 and never goes up, am I doing something wrong or not hitting the right sequence of buttons? the manual that comes with it is the worst manual I've seen on a product that's supposed to show you how to use it. All it shows is what the buttons do, but I need them to explain how to properly set it up without wasting hours of your life trying to figure it out. This is a nice idea but needs to be way more stream line for consumers and easier to use and not so complicated to the point where you need a degree in science technology.

Really wasn't impressed, It's really cheap the sensor is off from 2 of my other sensors you can adjust it to them but 2 degrees up later on the other sensors the spider farmer sensor is still the same I kept the deadband at 1 but heater doesnt turn off at set temp it will go 3 or 4 degrees past your set temp, that doesnt seem bad but its like 10 degrees higher than my other 2 sensors if my inline fan wasnt set to turn on to cool it would have fried my crop. I tried leaving a couple customer reviews on the spider farmer site of how i felt it won't let you post anything so i suspect all customer reviews on the spider farmer site are fake, not what i think a good company would do. I lost alot of respect for spider farmer
