Hey Sara! I rigged up a 120mm case fan to an old wall wart power adapter, and I just laid the case fan on top of the light, and WOW holy smokes!! What a huge difference in the temperature! It's barely even warm with this fan just laying on top running. If people worry about the heat, tell them to do this This is the way I'm going to run mine from now on. I think it will help to last longer maybe. ;):)

Did the temperature of the circuit board with the LEDs drop as well?

On the top surface it did yes. I dont have one of those gauges with the laser that measures surface temps, if you know what I'm talking about. But just by touching with my hands, that entire top surface is so much cooler, it kind of surprises me that a small case fan makes that much difference. I've never touched underneath where the LED's are while the light is on. Not sure if thats what you meant by circuit board with LED's. That hot top surface was my concern where the driver is, and I've seen a few other places that people are pointing those small clip on fans at the tops of the lights. I dont have anything to clip onto thats close enough for me to do that, so I thought of this. Hope it will help others looking for a quick cheap solution. I dont have a big setup. I'm just a closet grower, but it shocks me what I can get off of one plant in a bedroom closet with an LED light. :laugh:

Yes, I meant the surface with the LEDs. I intend to move the power supplies out of the tent after my current grow finishes. With my old 'blurple' of the same power draw I was getting up to 1/2 lb from a 2' X 4' tent. This grow won't be a good comparison, as I'm growing different strains, and going for seed. The plants will be smaller, so less harvest.

Hi sara. Heres another update for you on the 2 tsl2000 lights. They are truly brilliant and have killed my HPS by a mile on half the electricity costs too. The recovery from a major defoliation and re tying down is so rapid. It can only be the lights that have changed the speed i am used to getting. Heat is great too , we are in a heatwave here in the UK and i had no worries about too much in the grow room thanks to the lights.
heres a couple of pics.

Trimmed out and tied down again.9pm b.s.t

She is into flower about a week now, really doing a big stretch, pushing those tops out into view. Been eating so much too :popcorn: Seems like I have to click the light up another notch or two everyday.
:ganjamon:That is great! :55: Will you do some LST or scrog? :green_heart:

@SmokeSara can you or anyone else give me a suggestion on a good light to add with my Eco 600. I have it in a 2x4 tent and I'm trying to grow 4 plants. I'm only in week 4 of veg but I think it would be a good idea to give them some more light for flowering.??????
Hi Nola, the ECO 600 is around 250w, you can add another ECO 300 to get around 45w/sft, so that you will get great flower. ;)

Looking at the TSL 2000 now and I must say that is one very generous gift to be won lol far as the heat goes is it that bad?
Hi Nola, if you won't use the current ECO 600, you can also try the TSL 2000, it will give you very good coverage and also save a little bit energy. ;) (ECO will use at least 360w, this one one use 300w) :ganjamon:

Hi nobody, yes, as long as a normal fan is used, the temperature will go down dramaticly. Not to mention you usd it above the power supply,it will help even more. :D :D :D

Not at all Sara. great to see them showing what the lights can really do for us. I am amazed at the rapid progress and have flipped to flowering now and lowered them to 18".
also put a review on the mars site. so impressed , thank you

Can I daisy chain the ECO300 right off of the ECO600?? If so I'll be buying one tonight,:48:

Also on another note.... Those giveaways you got going on, are the winners name tagged so you know you won? Lol thanks for all the great help!

Mars Hydro TSL-2000: Grow Update & Interim Review

Remember the goal of this grow is to produce seed, not maximizing plant size and bud production. One branch on each plant of each of the three strains (Sapphire Scout, Candida, and Cream & Cheese) has been treated with STS (silver thiosulfate) to force them into production of all-female pollen. The two untreated plants have been moved to my other tent, and continue vegging out. Today was the start of 12/12 lighting and the stretch for the treated plants. Here is the tent today:


Plants Under the Mars Hydro TSL-2000 at the Start of the Stretch

The Mars Hydro TSL-2000 has out-performed the King X6 Dimmable 1800W COB LED Grow Light I used for my previous grows during the vegetative stage of growth. Both lights draw close to the same amount of power. The TSL-2000 draws 300.8W, while the X6 draws 315W. The Mars Hydro TSL-2000 is longer at 39.9" (1m) while the X6 is 15.8" (402mm), with the COBs covering less than 12" (300mm). What this means for us as growers is that the TSL-2000 provides a more even light intensity from side to side in the tent. In other words, the plants at the sides of the tent get close to the same amount of light as those under the center of the light.

The nodes are tight, and growth has far outpaced that of the plants I've grown under the X6. Both lights cost close to the same, with the X6 being $10 USD more expensive. I highly recommend the TS series of lights for the vegetative stage of growth. Remember, I have not reached the flowering stage yet, so I can't comment on its performance during that stage.

Improvements that could be made to the TS series of lights:
  • Individual power switches for each power supply;
  • bring the intensity adjustment out of the power supplies; and
  • add a level to the light's long axis.
The intensity controls are accessed through a cover on the two power supplies. This makes them difficult to access after the light has been installed. They are more of a 'set and forget' control than one that can be used to adjust the light's intensity throughout the grow.

There is no power switch on the light. It would be nice to have a separate power switch for each power supply. During parts of a grow (seedling, early veg) the plants have a much smaller footprint than just before harvest.

Both of these come into play for a light that is used from seed through harvest. At the seedling through early vegetative stages only half of the light is usually needed, and a much lower intensity can be used. As the plants are up-potted both sides of the light are needed, but the intensity of the light does not need to be at it's maximum. At the lower intensity the light can be positioned closer to the canopy. The control for the intensity can be a single potentiometer, or two potentiometers sharing the same shaft.

A level on the light would make it easy to adjust the height above the canopy. With two hangers for the light often one end of the fixture will be higher than the other. I currently use a level to keep it even, but it would be nice to have one built-in.

Suggestions on how to implement these improvements:
1. Modify the power supplies so that an external control can be plugged into them (3mm audio jacks).

2. Kit #1: Remote Power Supplies. This would include a mounting plate for the power supplies, and extension cables for the power supply to LED circuit board. The cable should be at least three meters in length. One end should be two cables 50cm long followed by a single coiled cable that stretches to a one meter length. followed by single cable without the coil, and connectors for the cables from the power supply. The coiled cable would keep it out of the way, and the tent looking neat.

3. Kit # 2: Extra Controls. This would have the power switches and intensity controls mounted in a connection box. Pig tails would be provided that plug into the the power supplies modified as per #1 to control the intensity. Power connections would be a screw terminal style making it easy for those without electrical experience to make the connections.

Note on heat:
The light does get hot, as there are no cooling fans. Whether fans are used or not, the light will produce the same amount of heat. With the fans some folks have installed, the heat is drawn away from the light; BUT the same amount of heat is put into your tent. I'm certain the engineers at Mars Hydro have taken this into consideration when designing these lights. The higher temperatures will still be within tolerances for a long life.

Overall I'm very pleased with the Mars Hydro TSL-2000. It has performed very well during the vegetative stage, and I'm looking forward to seeing how it does during flowering. Whether you have one of these lights, or not, please help our sponsor Mars Hydro by commenting on my suggestions.
