Totally Worth It!
Well worth the money. Plants that did not winter well last year when I used lights that are obviously targeting frugal shoppers. I spent the money this year, and what a difference. I actually had to reduce the light intensity because I don’t have room indoors for the plants to grow as much as they would if I left light at full intensity. Setup and assembly were easy. Controls are high quality and easy to operate and understand. Light level, outstanding.

Impressive Lighting Solution for My Indoor Grow Tent!
Amazon Review for SF 1000. Impressive Lighting Solution for My Indoor Grow Tent! Review: I recently purchased the Spider Farmer SF 1000 LED grow lights, and I must say, I'm thoroughly impressed! I initially bought one unit to grow a single plant. but I was so satisfied with its performance that I ended up purchasing three more over the span of a week to fill out my 4x4 grow tent. Now, with a total of four SF 1000s in my indoor grow tent, the lighting is absolutely fantastic! First and foremost, let me commend Spider Farmer for their exceptional customer service. From the moment I reached out with inquiries about the product, they were prompt and helpful in providing all the information I needed. They truly value their customers and go the extra mile to ensure satisfaction. In terms of product quality, the SF 1000 is top-notch. The build is sturdy and durable, giving me confidence that these lights will last for a long time. The full-spectrum lighting output is remarkable, providing the perfect balance of light for my plants' growth stages. I've noticed significant improvements in their overall health and vitality since using these lights. Energy efficiency is another standout feature of the SF 1000. These LED grow lights consume minimal power while delivering impressive light intensity. They're environmentally friendly and help keep electricity costs in check, which is a big plus for any indoor gardener. The installation process was hassle-free, thanks to the well-designed hanging kit provided with the lights. It made mounting them in my grow tent a breeze. Additionally, the adjustable dimming feature allows me to fine-tune the light intensity according to my plants' specific needs. I can confidently say; and not just because their stickers are fire,that Spider Farmer as a company has won me over with their SF 1000 LED grow lights. The combination of their outstanding customer service, high-quality product, energy efficiency, and ease of installation sets them apart from other popular brands with a similar product selection. If you're looking for a reliable and efficient lighting solution for your indoor grow tent, I highly recommend giving the Spider Farmer SF 1000 a try. It has exceeded my expectations, and I'm sure it will do the same for you. Happy growing!

Perfect for starting a family...
I absolutely love this grow light. It has top of the line diodes, great heat dissipation, and couldn't be more perfect from seedling growth (the dimmer is quite valuable) through early and mid vegetative stages. If only growing one plant it may be quite capable for flowering stages as well although I start using a bigger light in this stage of growth. The price tag is very agreeable as well considering the array of much more expensive grow lights on the market. Your girls will reward you for your months long efforts.

Great Product , Highly recommend over other cheaper lights.
So far my favorite light of all my grow lights. I really like the fact I can dim the lights to a reasonable power without having to raise and lower my setup. The light is strong enough for most of anything I'll be growing, but also capable of being toned down for delicate seedlings. Other companies seem to spend their time worried about packaging, which is like putting lipstick on a Pig. You can dress it up, but it's still a pig. Thank you Spider Farmer for putting out a quality product. Only thing I would suggest, is the company really needs to put more effort into making sure both sides of the aluminum board is smoothed down. Mine has bad scar marks from production that should have been smoothed out before it moved on thru production.

Awesome value lights
These lights are awesome, better than I expected, for the cost. A real bargain. My lights died on me halfway through flowering. I don't have extra money to squander on short notice. I did a little research on the best lights at a low cost, and I came upon these lights. I'm very satisfied with them, and so are my girls.

Great lights for indoor gardening needs
Great lights for indoor gardening. The light intensity and spectrum promote healthy growth and plants are thriving. Light stays cool, dimmer functionality is a nice feature. Super light weight, build quality is very good, and very pleased with performance. Would definitely recommend. The customer service from Spider Farmer is second to none!

Cerca de una semana de uso y debo decir que estoy muy feliz con este producto de spider farmer. Tenía alrededor de 3 plantas de chile chiltepin creciendo bajo luces de un precio mucho más bajo dándole un espectro azul y la diferencia conforme al crecimiento al cambiar a spider farmer es increible, como Luz y noche. Muy muy recomendables para una inversión a largo plazo.
