The Penetrator 168X Extreme is the most powerful commercial LED Grow Light in existence for 18" x 5' areas, with PAR output expected to match a 400W HPS! Our advanced spectrum provides lightning-fast growth from seed through flower, creating HUGE yields, super-dense flowers, and fruits so monstrous you'll be scared to look at em! For those who simply won't settle for anything less than the best, the 168X Extreme is your LED Grow Light. Prepare to be amazed at what only 175W can do!
The 168X Extreme is designed for use in a 2 x 5 area, and is ideal for grow racks, grow tents, or any growing operation where versatility is paramount. Using multiple 168X Extreme lights vs 1 larger light gives you a more even spread of light intensity throughout your garden, and allows you to raise or lower each light to meet your plants' needs.

Superior Technology. Independent Testing
Penetrator LED Grow Lights have evolved over 4 years of research, independent testing, and hardcore development to become the absolute Best LED Grow Lights in the world. In fact Penetrator LED Grow Lights are undefeated in independent, side-by-side grow tests, often times yielding 2-4x more than our competitors! This is achieved via a combination of the perfect blend of light and intensity, which other LED Grow Light companies have been unable to duplicate.
Unlike other LED Grow Light companies, we don't just make claims of being the best, we prove it! For example our 126W Penetrator produced 3.7x more yield per watt compared to the 186W PPF-800 from Haight Solid State. Likewise our 119W Beta light produced 2.7x more tomato yield compared to the 120W LED Grow Light from HTG Supply. Our 50W prototype light produced 2x more ripe tomatoes compared to the 45W Glow Panel from Sunshine Systems, and our 63W Penetrator produced 2x more yield per watt compared to a 90W UFO from eBay! Best yet, our LED Grow Lights always produce at least 2x more yield per watt compared to HID! When it comes to having the best, you're not going to find results or proof like this anywhere else!
Buy a Penetrator 168X Extreme LED Grow Light to experience what Independent Testers and Universities have already proven: that nothing compares to the power and technology of Hydro Grow LED Grow Lights, with Zero Stress, Zero Bulb Replacements, and PHENOMENAL results!

If for any reason you are less than impressed within 90 days of receiving your product, you can return your lights for a 100% refund of the price you paid less the original shipping cost (costs listed below).
Returns are limited to (2) LED Grow Lights per customer, and return postage is the responsibility of the consumer. Return merchandise must be in as-new condition, in proper packaging, with all appropriate power cords and hanging pieces. If any part is missing, the sender will be charged additional fees for those parts. The refund will be processed via the same method used for payment within 48 hours of receiving the returned merchandise. We do not offer returns on refurbished or used LED Grow Lights, nor customized (color, lensing, etc...) or international models, as these are special order items.
Order cancellations are only offered in the event that your item has not yet shipped. If you wish to cancel your order, a 20% restocking fee will apply. There are no exceptions to this policy.
In the event that there is a problem with the functionality of any of our grow lights, we require photographic evidence displaying the said problem (ie: if two light engines are not turning on, a photograph showing it). If you are unable to provide pictures of your product, we will supply you with a return address to send the light, where we will determine the damage and either fix the light or replace it with a new one.
If the light has been tampered with or it is found that the damage was caused by the customer, there will be a repair fee associated with the return of your product. If it is determined that the product is unrepairable, we will notify you immediately. If the warranty seal is broken, your warranty becomes null and void. If damage has been caused by abnormal use, neglect (such as dripping water), wrong input voltage, dropping or breaking the light, etc..., the warranty is void. Warranty coverage is ultimately left to the discretion of Hydro-Gro LLC.
We reserve the right to refuse warranty repair or replacement service to anyone. For minor repairs such as a power supply replacement, we will send the new part to you with instructions on how to replace it. In the event that the new part does not fix the problem, or there is a problem which is more complex, the light will need to be returned for a warranty replacement. In the event of a replacement, we will send you a return shipping label for the defective product, and after it has been received we will send out a new replacement unit to you.
The defective unit must be returned in its original packaging and box. If you are unable to wait for a replacement, we offer expedited service for a deposit. This deposit varies per light, but ensures that a new product is shipped to you right away. After you receive the new product, use the return shipping label included to send the defective light back in it's original packaging and box. Once the light has been received and inspected, your deposit will be refunded.
