Spider Farmer SF4000 450W LED Grow Lights With Samsung LM301B Diodes, Deeper Penetration and Dimmable Full Spectrum Lighting, High PPFD & Low Heat

My golden torch cactus looks slightly etiolated after this last winter since it was cloudier than usual, I put them outside in the morning sun until this grow light came in. I hope it’ll help even out the etiolated top a little bit and start growing in fuller. I usually keep my cactus outside in the summer anyways , however I have to bring them in if it rains and I constantly battle pests. I’m going to skip it all this year and start keeping them in a tent from now on, that way I don’t have to deal with pests like mealy bugs and I can admire them at 12am instead of going outside with a flashlight like a crazy person. I have 7 more cactus that will be delivered in the next coming weeks, so I’m hoping to have the lighting dialed in so I can introduce my new desert pals. Eventually I’m going to expand my collection significantly so another light in the future will be in the works. Great quality , heavy and great size.

As you see these plants are from use the spider farmer led grow lamp. Works great . I have used two grow seasons and a few times to start seedlings…. Great for 3x3 grow tent and perfect coverage. Easy to assemble right out of box. Great quality.

This light is worth the few extra bucks . Seriously I returned all of my cheap Amazon LEDs and took that money and bought this bad boy. So worth it. Just in case you have a VIVOSUN controller I think it’s E42? The sf2000 will work with it and you can use it like a smart light from the app. That’s the only thing I was worried about. It worked out for me . Regardless this light is the best it covers my 4x2 great even at 45% @ 24” high . Top notch . And it comes with dope stickers 😁😎

Great product, great efficacy, reputable brand.

One of the power supplies went out on my light and I am having a very hard time getting it warranted by spider farms after 30 days you can no longer get it warranty through Amazon you have to go through spider farm and they are very very very hard to deal with. I have 2 of them and they have been good light. Very happy with light very unsatisfied with customer service.

Great LED’s, fantastic efficiency. Rugged as hell and has effortlessly trucked through humidity, gnats, dust, debris, storage, and shipping multiple times. Still runs like a champ over 3 years later. Super nice for keeping plants and cactus going over the winter; it’s so good at passively dissipating heat that it noticeably warms up whatever room you’re in.Even my dog doesn’t know the difference between these lights and sunlight. Recently bought another one to use for starters. Worth every penny.

Excellent light from spider farm they have many other lights also to upgrade if needed as soon as I opened the box it was quality from the start excellent light intensity

Bought my light back in May of 24 and everything was great until one day I came home and it was dead… It had been 10 months, so it was still under warranty.. I contacted Spider Farmer customer support and they were GREAT! They sent me a freshly refurbished replacement within a week… Thanks again Spider Farmer!😊✌🏽
