This light was correctly tested by the Migro camp (Dr. Coco) it smashed the Growcraft X 3-330-3bar in a true grid 2'x4' non reflected floor at 19"-24" perfect par at 19"1/2🤓

I love this proffesional growing channel.

Adding a bit more IR/ RED, is going to make these very admirable, in my opinion. And they did. Thanks GA!

Great review great lights

So I just bought the sp250 with no dimmer. The week later they came out with the sp250 with dimmer?😜

Does it produce so much heat as the rest of MarsHydro do ?

looks like a step up for MarsHydro! cheers all

Can't wait for the cuke grow!

Where is part 2?

Good review. Just as a correction - that box is not called a ballast with LED lights, but a driver :)

What do you think would be an optimal dimmed wattage for veg.

Depending on the environment and plants that your gonna grow about 50% is rough guide for growing weed as cannabis likes a high amount of light, then 100% for flower. A little less for a lot of salads

Meanwhile should make a heat sink that is also the balists cover

I'm unabe to understand how light warm / wattage / lumens / wavelength relate to each other. Some videos says we should focus only on the wave lenght because that's what matter the most, and that the best light for plants is not visible to the human eye, but at the same time, that people keep measuring the lumens of the light (how far away light goes). On the other side we talk a lot a bout light warm, the same warm could be achieve with different wavelenght, isn't?, so, why people say things like: "light around 4000K is ideal for....", should be considering only wavelength? I have seen a lot of videos and I'm still completely confuse about all of this :(

Lucyfer Lucyfer, they are not measuring lumens usually. They are measuring P.A.R. That stands for Photosynthetically Active Radiation. That is defined as light that plants can use for photosynthesis. A lumen is the light output of one full moon. Watts are of concern because of cost of electricity and because higher watts means higher heat too. The wavelength is important too, to get good growth and a good product. It's all important. I just went on my LED education journey a few months ago. At first the information can be overwhelming, but patterns emerge after a while, and the good information will stand out. There are a lot of light manufacturers competing for our money! Some of them, like Spider Farmer, send free lights to growers in return for honest (pronounced 'positive') KZread reviews ;) It seems that Mars has seen the value of this promotion and is doing the same thing. These Mars SP-3000 videos all just popped up in the last few weeks.

One of these should be good for a 2x4 tent right?

@@crunchnuts I love mine! I"m on the end of the second grow. I just won a SP6500,so the 3000 will go back in the box for a little while. I’ll probably will use it as a clone light in a 2x4 to make auto seed and crosses. The 6500 is gonna grow some monsters. Keep that 3000 at 22in at the closest to the top of your canopy, unless you're running CO2 all the time

Be careful with mars lighting , I have had 4 of the older styles ( last years ) either draw power of a timer in the dark " faintly" right out of the box , or like the 1000w after 6 months of use . Just keep an eye on them in the dark on a timer is all i can say , maybe the issues ( like with the 600w not being timer compatible per mars techs ) have been fixed . Mars sent me instructions on how to wire them to make the 600 timer compatible, If they know this , then why sell them without telling people?, the faint light can cause huge problems for cannabis growers and its very faint , the only way to tell is to flip them while on a timer in the dark , depending on the light height , or get on your hands and knees and look up :xD.

This video was great until the very end when he mentioned he's going to grow what cucumbers lol.

Per Mars Hydro: For the SP 3000 and SP 6500 lights, the previous version is with IR and UV chips. Since March, we have moved the IR and UV from the SP 3000, SP 6500, and FC 6500 lights. Also, the new FC-E6500 light doesn't have IR and UV chips. The reason is that these lights' main customers are personal growers who pursue the best results or the commercial project customers; they prefer to independently control the IR and UV lights time, don't need the IR and UV chips on the light itself. Mars Hydro also will issue independent IR and UV lights in the second half of the year.

I’ve never noticed any abnormal stretching. Don’t see how that would even be an issue with the spectrum they use. They’d have to be very warm tinted for that to happen and they are not. Or they’d have to use a ton of IR which they don’t.

Ok. I get people have hobbies. But in spending thousands on cannabis a year. I understand biting the price for something expensive like pot. But why do people buy 800$ in lights for cucumbers. Real question. Is this just for your channel. People following for cucumber growth arent going to spend that money. People growing cannabis are your market bro. Its It's legal.
