So far so good using an entry-level… So far so good using an entry-level kind LED product and looking forward to harvesting my pineapples and exotic fruits. If I had to compare all the brands across the marketplace for this purpose I would equate kind LED as a BMW in the grow light market. After all, you get what you pay for and that’s why I paid extra to get the kind LED lights.

I am beyond words with the performance I am beyond words with the performance, quality, and fine tuning associated with my new X². Paired with the GS1 Controller it is head and shoulders above anything(lighting) I've experienced to date. It's a real "GAME-CHANGING" combo! If you are on the fence the Kind X² is your answer. ........................... Also; I have been growing "QUALITY" tomatoes long enough to be considered above novice level in Most circles. Given that, I have developed a fairly extensive play book as far as Macro/Micro nutrient needs/efficiency.(as it would relate to "high" quality tomatoes) I was recently introduced to the "LOTUS" line of nutrients. I WILL NOT reveal my prior nutrient Branding choice, or application rate,... I will say however that my first LOTUS tomatoes were every bit as FLAVOR/FULL as before, BUT NEARLY 50% LARGER!!(actual size may vary lol) AND ITS A BREEZE TO USE!! Premium Results, Minimal Effort . . .? "Sold"! Sincerely : William-C: McCleery.

Best light there is for a 2x4 Tent Alright this light is probably the best light you can buy for a 2x4 tent. It's probably overpowered for my autoflowers, but it has dual dimmer knobs in case your DLI is too high. I really enjoy the spectrum control this light has, and I've noticced my plants finish faster underneath this light. Not sure if its the added UV or what, but my plants grow and mature faster under this light. Also the coverages for a 2x4 tent is near perfect and I'm astonished at how the corners of my tent still have a high PPFD value. It's super bright, yet doesn't make my tent warm up like other lights that are over 400w. If you want the best possible light for a 2x4 tent, don't bother looking anywhere else.

The X40 lights worked as advertised The X40 lights worked as advertised. I did have to remount the ballasts on the sides as I supported 3 lights in a row on aluminum rails, and didn't have enough top clearance to accommodate the standard top mount, so that is possible. Otherwise, my radishes germinated in 5 days and lettuce in a week. Very happy.

X330 Control Box I had an issue with my X330 Light (Brand New), the UV side would come on then cycle off after 20 minutes. I contacted Michael from GSI Support who mailed out the new control module that day. The fact they were able to troubleshoot the issue over the phone and immediately mailed a new controller. Your extra efforts to help me did not go unnoticed. Thank You again,and look forward to being Kind Light customer forever !!! Customer Service does make a difference....In addition Jessica Sage "On Chat" did a remarkable job as well, very quick to respond and customer service was beyond reproach - What a Team !!!!!!!......Thanks All !
