Greenhouse Pro® Series

A couple years ago I added 2 of these to my grow to frost up the plants in the final months. Since then I’ve found the have a secondary function of inhibiting powdery mildew. I just added 2 more to my garage grow to help with a mildew problem there.
I suggest running them for about 15 min a day in early flower and as you get to the last weeks run them for 15 min every 2 hours while lights are on

I am very impressed with these lights!! Very well made! They work as advertised!! They stay kool with that gigantic heat sink and the two fans. I am very happy with my purchases.

I’ve tried all kinds of lights from mh to leds. Your 1100 is the best out there. Don’t hesitate to pull the trigger on this one. You will not be disappointed!!!!

I cultivate my medicines when I can. I have two of the UVb lamps. My eye apeal has always been there as well as thc levels. The difference I'm seeing is in the smell and taiste. I'm sold and will purchase again.

So far so good. I haven't actually used them yet. I will say that they seem simple and well built. Im sure they are exactly what they claim to be. I expect nothing but the best from CLW!

The lights kick ass we have used them for many years already .They have saved us lots of money and put out some Dank .Believe me these lights are bad ass . We have had many crops and made much money .If they do not work for you then you do not know what you are doing .

This is my third light from California Lightworks - couldn’t be more pleased with its performance so far.

3 550s in a 4x8. 5 grows. CLWs recommendations are very good, videos too. They have an article that addresses what I'd like to report.

Multiple lights require hanging in an arc because of footprint and intensity. It also required me to reduce RWB 10%. Just saying get a PAR and test PPFD.

Damn good product. Grows real well!

I am a novice grower and I totally and completely suck at anything having to do with electronics or machinery. My old HPS died mid-cycle and I took a chance on the SolarXtreme250 from California Lightworks and I literally couldn't be happier. My plants are loving the rays from the light and this thing is built to last with a rock solid housing that makes installing or moving the unit a breeze. Five stars. (jumping high-five/freeze frame)

EDIT THIS BIT OUT; i used to be a really good copy writer/copy editor so if you guys wanted to give me a discount on the next size up solarxtreme I'd be happy to write more and send some pics. probably a long-shot but worth a try.

I have had some of the best grows using the solar extreme 1100 I have four of them in my grow room and I grow 12 monsters each time. I can't complain like I said I have had the best grows with these light .if I knew how to put pictures on this review you would be excited to get your lights . I'm going on four years of growing none stop .

Christi is excellent and went above and beyond to help me. Really, she is exceptionally talented. I received the lamp and the packaging was excellent and properly safeguarded against breakage. I will use today and rest of grow, which is on its last days, so I can't fault the lamp for my not having ordered it sooner. I took pictures before installing and will continue to capture more images every day, in an effort to record tangible results over time. I will report back and update this post. Initially, product appears of good quality. So far, so good!

100 % satisfied with my purchase using it now will post results when grow is completed

I was using another brand of lights, and the results were ok but not great. This light improved the density, the appearance of the buds, the smell and most importantly the trichs. I used this in a 4x4 tent and the end results were amazing. i even have pics to prove it. Christie was a big help and answered all my questions.

Received light and controller everything looks nice and bright gonna put it to use soon but no complaints everything looks well built

I’m happy with quality of light and wires. The box it came in was packed nicely and the light was not damaged in shipping. I do not understand the bad reviews on quality. Can’t wait to see results.

I really like that they don’t heat the tent up. Two 250’s seems to be enough light for my 2.5x5 tent. Customer service is on the ball too.

The light and controller work very well. I have been using the color spectrums indicated in the controller instructions. It is incredible how the vegetable plants in my hydroponic garden have increased in size within the past few weeks. The roots are hardy, the stems are thick, and the leaves are a beautiful dark green. I look forward to the flowering stage to see how well the vegetables will grow. Thank you, California Lights, for the SS 550. I purchased it during a 30% off sale. What a great price.

I bought a controller with my first SolarXtreme 820 and I'm sure glad that I did!! The controller
really is. A must have to be able to control your lights properly!!! And the really nice thing is that this controller is real easy to set up!!! Do yourself favor and order it with your light because if you don't you'll just be calling back to order one!!!

Someone jacked it off my porch. Damn, I bet it was great

I have to say that so far I am totally impressed with my Solar Extreme 820!! I really did want the Spectramax 1000 but they were out of that particular grow light. Christy talked to me about the Solar Extreme 820 and told me that the engineers at California Light Works were really excited about its lighting ability and the way it’s built!!! Needless to say, she talked me in to buying one and I’m really glad I did!!! I’ve had it on my plants now for a little over 2 weeks and I am really impressed at the light output of this 820 watt light!!! It has been doing a great job and the plants are growing fantastic and looking just as good as they do under my 1000 watt Spider Farmer SE1000W light!!! They have just started budding and I am totally excited to see how my new Solar Extreme 820 will perform but so far I’ve been pleasantly surprised at how well this light is working!!! Something I’d also like to touch on is the weight of this light!!! It is very sturdy yet really lightweight, about half of what my Spider Farmer lights weigh so they’re much easier to install and also raise and lower!! The Solar Extreme even comes with all the hardware to hang it!!! Optionaly you can buy a Controller like I did and it gives you flexibility to set the light up however you want to!! Lastly the Controller offers sunup and sundown control!!! I hope everyone enjoys their light as much as I have so far!!! Happy Growing

I have not started a grow yet but the light is extremely bright at 100%. Kinda curious how the plants will react with the controller option of 1/2 hour of dimming and lighting when it’s time for lights on or off. I believe it will definitely do the job.

Flimsy and low light output. Good for a mobile above the baby crib,- hmm... not - too heavy for that.
May be good for sprouting, perhaps.

It seems the frost has almost doubled on my buds! Incredible product!!

Have had 6 plants under this light for 12 days, 2 months since germination. Repotted into larger containers same time light was installed. Plants love the light are starting to take advantage of bigger containers. Not sure how long grow will take but things are pretty good now. Very interested in seeing how Gorilla Cookie, Northern Lights, Blue Dream and White Widow turn out. I make oil with cannabis and olive oil for arthritic hips and general well-being. Love growing my own, making my own medicine. Also giving buds to friends.
Light is a quality product. Figured controller set up no problem. 18/6. Used ratchet pulleys to hang.

Awesome, works great easy to program
