Love it
I bought the 32 pint spider farmer dehumidifier I have contacted the company to let them know. they reached out to spider farmer and replaced it.ty Jermey!!
this is my first vivosun tent, my other two tents are another brand with vivosun controllers and carbon filter/duct fan combos. I was worried about the reviews on the zipper light leak but so far there has been no light leak on the tent. the aerowing is pretty heavy but with the heat syncs and embedded fan I expected some weight
everything so far has been awesome I am a fan of vivosun product!
Hands down the best packaging. I ever had everything came one box before. They used to send it all different times the packaging still blows my mind, everything's labeled. Even though this company screwed around doesn't make sense. Sometimes I still have 4 setups from them and I. Keep buying from them.
Cause they have good products.
Very nice setup
The light is full spectrum vsfd6500,and blinding strong. This is my first indoor grow and I made alot of errors and I'm still growing killer buds. I would definitely. recommend this kit for the price, you won't beat it...
I’m a massive fan of this light and Spider Farmer! I actually own several Spider Farmer G series lights, and let me tell you, every single one of them surpasses expectations. This particular light, just like the others, comes with a durable aluminum support frame that won’t rust. The best part is, it offers different light levels that are super easy to adjust for sprouting, growing foliage, and flowering purposes.
These lights are absolutely heavy-duty and of professional quality, so you can trust they won’t let you down. I highly recommend them!
I am very pleased with this product and I believe the pictures will explain why.
Luxurious setup, provides excellent output, also gives peace of mind knowing you have a safe and reliable investment.
This tent kit came packaged very thoughtful with good directions. It went together easily looks clean and stealthy. I'm already impressed. Looking forward to get to growing.
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!
After all the research I did I picked this tent on overall value. It has reinforced corners and is more than strong enough to support anything being hung from the ceiling with the 4 bar cross system. Some of the big names don’t have reinforced corners and I don’t need to hang 300 pounds. I’m growing not smoking meat for a restaurant. Smart Control is sweet. Over all I’m happy.
this 4x4 tent kit definitely lives up to its reputation. the control hub was on point and easy to use making my grow experience very pleasant
great high quality grow tent
I have no complaints. There's a little behind learning the app but once you learn it everything is easy to adjust and monitor. The tent quality is top not in my opinion but this is my first tent so this is solely a first timers opinion and not knowing how other product perform.
very spacious and simple to set up.
great products
I would be more than glad to recommend this product to anyone interested in indoor growing it’s very easy to maintain as long as you are able to check on your grow a few times a day
Love this tent it’s amazing! The setup was easy and my grow tent is thriving! Thanks VIVOSUN!!!
I still struggle with the E42A controller, but other than that, everything works perfectly. customer service is awesome as well
Love the tent
Was very easy to setup! Its doing great so far!! Using it as a space for my Veggie starters until my seedling photos are ready for their home.
Good value and a good upgrade for anyone looking for more space. The light is super powerful !

Damn good product. Grows real well!
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 love these Solar System lights with the controller! My plants are beautiful and potency is optimum!
SolarSystem® 550
I have hung and put 3 of the 6 on High Blue, Medium White and Red on the one side and the Moringa and Theobromo Cocoas are getting bigger leaves and bushier. The Moringa was always leggy before.
On the other side I have 3 lights on High Red, Medium White and low Blue to get my Citrus and Dragon fruit to flower and fruit.
My Arboretum is 36 ft Long, 18 ft Wide 12 ft high in the center. Since I am in the San Antonio, TX Area. The Sun gets Very Hot so I have a White Opaque Polycarb Roof. It has been blocking the Blues and Red light and my Trees were getting Leggy and NOT Fruiting.
I also have some beautiful Double Mahoi Banana Plants that have been giving me great fruit.
Soon it will be getting cold at night and I will have to bring in my Papyas and Haas Avocados trees.
I bought 2 controllers on each side so I can divide how I use the lights between the trees on each side.
So far I am very pleased with the results I am getting with these Solar System 550 Grow Lights!
