Yes, it is 4x4 tent. I like the HLG design and review. But because of my budget, i finally chose two Mars SP250. It is bright enough to light the dark room. lol. So far so good.

I have used the Mars SP250 for almost two weeks. the only concern is the heat around the meanwell driver.
it is very hot when touch the driver after 18 hours work. The temp in tent is still normal right now. I adjust the power to 200W with a screwdriver.
I am not happy there is not a more convenient set to dim the light.
The veg stage will end soon. seems plants cannot wait to go into flowering stage. I dim the light to 190W with a lot of effort.
Now, it is the time to change it into 230W for flowering. I bought an extension cord from Mars rep to put the driver out of my tent.
Then the temp went down a lot. The heat problem could be solved in this way.
Anyway, i still like the light performance so far. ;)
Another month passed. It is near to harvest. I want them to be more mature. So will grow more days.
highly recommend the SP250 to low budget fellas. Like becomes love now. Lol.
