It comes with a pump. The water runs about 44 C (which is what the manufacturer says it will do) so the dropping water level is just a question of evaporation. We have added a fan for this round so the temperature should be lower in the next test following greenpinelane's experience.

Now that we have fixed the problem with the tank not too worried as will install a chiller (no hot tub to heat lol).

The pump flow with only one kit is not that strong. Like a aquarium pump mostly.

I wasn't around for harvest so no photos this time. We'll fix that on test 2.

You could always use city water and a drain to cool the lights but thats just wasting water... a chiller is the way too go

does it come with a water regulator?

can you post pics of your harvest? im very interested, been at this light a lil too long.... thanks
ledgrowtester Reviewed by ledgrowtester on . Smartlamp LED grow test Not sure if I am putting this in the right spot but here goes. Hi guys, thereā??s been a lot of talk about growing with LEDs in the past year and we finally took the plunge after doing a bit of research so I thought Iā??d share some of our results so far. First, we went with the TI-Smartbar from Theoreme Innovation. After looking into the various lights out there it seemed like they had the best technology and the most powerful lamps compared to all the others some of which looked like Rating: 5
