The manufacturer says in series not parallel.
Apparently the increase per lamp is about 3 degrees in the type of one kit system we are using. The advice they give is that you increase the water flow as you increase the number of lights in series. The water pressure with this one kit is really low. Obviously the thermal transfer ability of your cooling technique (water basin in this set-up) has to increase with the number of lights.

It's probably better in parallel atleast thats how I'd hook it up despite their reccomendations. if your water level is decreasing or evaporating then the water must be too hot. You could always use city water and a drain to cool the lights but thats just wasting water... a chiller is the way too goQuote:

can you post pics of your harvest? im very interested, been at this light a lil too long.... thanks
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.

The government isn't fast, but, hey, at least they're slow.
We'll post an update as soon as we are able to start the new grow.
