With ther new itimer its been a game changer for my grows

I GAVE IT 5 STARS DO I NEED SAY MORE

Thank you

Here I review the Mars Hydro Adlite 30w deep red grow light bars, which come in sets of two.These lights are deliciously brightly red at the important 660nm wavelength. At flowering height in my setup, each bar delivers about 60 micromoles per second to the plant canopy, resulting in a DLI of 2.6 for a 12-hour light day. My plants seem to love this red light.There are small brackets on top for hanging these lights. Alternatively, if like me you have a Mars Hydro FC-3000 main light, you can rest the ends of these lights on top of the main light and then velcro them into place.The downside is that the cords meant for daisy chaining cannot be detached, so one cord hangs awkwardly off of one end. Daisy chaining cords should be detachable.

... that they would sell these lights separately but only give you one pair of plastic mounting racks per order. So if you only want to use one type of light bar like UV alone, there is only one set of racks to mount the bars to your light. Are you supposed to put both the UV bars on the single pair of racks and group them over one small area of your plant? That seems extremely cheap to me, especially considering these bars are way overpriced at over $60 for just one set of lights. I think adlights are a good concept, but the execution is needlessly complicated and the cost if you wish to use all 3 types of light bars are exorbitant at approximately $200 for the full kit. I would rather have 2 pairs of mounting brackets than the cheap timer they include in the package. That way I can at least mount both my bars.I purchased this to see if it is something I want to add to my grow lights, but I don't like that there's only one set of brackets to mount these UV bars unless I buy a second kit. This is going to frustrate a lot of people who only want to add UV or Deep Red to their flower tent and not the whole set of adlights.Buyers beware. You are only going to get one set of brackets with this kit, and a cheap timer you probably won't use. BTW, the timer has two lights in it that could cause hermies in light sensitive strains. Proceed with caution with the timer. You've been warned.

I use these lights based on Mars recommended schedule. 15 minutes before lights on, and 15 after. Started using in early flower, and in less than a week, I saw the leaves reacting during each session. Before lights on, the leaves were UP and praying, as though they were anticipating lights on. Then, with lights off, the last 15 minutes I observed the leaves relaxing, as though they were going to sleep. This during the first 3 weeks of flower, to avoid excess stretch.Now, from week 4 through the end, they will be on beginning with 1 hour per day, to eventually, 2 hours a day, just to see if the so called "Emerson Effect" exists when using far red.So far, during the early weeks, they do what Mars says they would. The plants are ready to wake up, and go to sleep as described by Mars. Can't wait to see what the harvest will bring !

Exactly as described, easy to install online with current lights and wiring was simple

Good price for a good product. it does what it says if used right. don't forget you can't leave them on for to long . read recommendations.
