Exclusive Limited Time Offer: GrowAce.com customers will receive a FREE pair of Yield Lab LED grow room glasses with the purchase of the Spider Farmer SF4000 LED Grow Light System ($29.95 value!)

 

The Spider Farmer SF4000 grow light is an energy-efficient LED as its par efficacy is reported at 2.7 umol/J. The SF4000 LED grow is equivalent to 1000 watt single-ended HID fixture. Each light fixture consists of 1152 Samsung LM301B LED chips,4 IR chips, 56 Deep Red LED chips. The LED emits full-spectrum white light (3000K, 5000K, 660-665nm, 760nm), which imitates sun-like properties and boosts plant growth.

  • Aluminum Heat Sink: Aluminium has excellent thermal conductivity properties, which allow quick heat dispersion and also help increase the intensity of light up to 20%.

  • Sun-Like Spectrum: With the full-spectrum white light, consisting of the color temperatures:3000K, 5000K, 660-665nm, 760nm. It ensures that your plants get nourished just the way they would have under natural sunlight.

  • Samsung LM301B Diodes: These LEDs ensure deeper canopy light penetration, and you can expect to get 40% higher yields with very less energy consumption. These diodes are the best available in the market.

  • Dimmable Meanwell Driver:With the Meanwell dimmable drivers, you can take control of the energy consumption of the grow light system, improve light efficacy, adjust current amplitude, save power consumption costs.

The Spider Farmer SF4000 LED gives a full spectrum white-light which imitates the sun-like properties to which plants respond in a similar way they would have to the natural sunlight. Therefore, the plants get full-nourishment even when placed indoors.

3000K (WarmWhite Light): Helps grow the flower size.

5000K (Blue Light): Boosts the plant growth rate, boosts germination.

660nm (Red Light): When used in combination with blue light it yields more leaves.

760nm (IR Light): Promotes higher yields by speeding up the phytochrome conversion process.

The quantum board is embedded with the Samsung LM301B Diodes, which allows better canopy penetration to promote photosynthesis in plants. When mounted at 24” height, its flower footprint is 4' x 4' or 5' x 5' and at 36” height its vegetative footprint is 6' x 6' area.

The fixture utilizes the passive heat management system to maintain the temperature of the fixture. Due to the absence of cooling fans in the system, the heat dissipation process is carried out noiselessly. The Meanwell heatsink is made out of aluminum as the metal possesses high thermal conductivity properties- which helps in getting rid of the heat more rapidly.

The led light consists of 4 infrared chips (IR). Exposing plants to the infrared red rays helps improve the quality of buds, promotes stem growth, and shortens the growth cycle, for getting quick results.

With the dimmer, you can control the amount of energy being consumed, control the grow light system, improve the light efficacy, make adjustments with the current amplitude, hence save the power consumption costs.

The LED grow light is recommended for grow tents, grow rooms, large indoor grows, vegetative growth, and supporting plants at every stage of their growth cycle. The LED grow light fully supports hydroponic, aeroponic, or aquaponic systems. The SF4000 LED Grow Light System is ideal for growers worldwide.

Excellent set at an affordable price
Size: 18-Piece, Style: Traditional Handle Design
I'm not a chef, nor a knife aficionado. My wife and I both enjoy cooking and prepare our meals at least 5 days a week. We had a medium quality knife set that was around 13 years old. Due to improper cleaning (placed in the dishwasher most of the time) the blades dulled and rust spots appeared. We decided that a high end set might be a nice gift to ourselves, and looked at the premium brands available. Being non-professionals I started to feel uncomfortable spending upwards of $300 on a knife set. I have been watching these knives for a while now, and have read countless reviews, both good and bad to help me decide if these are worth getting. Having purchased other Amazon Basic items I felt that these were a safe bet, and if I were unhappy I could easily return them. Upon arrival the knifes looked fantastic. They were very nicely packaged and easy to safely unpack. The block was in perfect condition (some reported cracks upon arrival). I inspected the knives and all appeared to be in perfect condition showing no dings, burrs or warping. After a quick hand wash and dry I placed them all in the block. I did have a slight issue with one of the steak knife slots not fully cleared and preventing the knife from sliding all the way down. I was easily able to clear it using an old steak knife as there was only a wood chip stuck in the slot. I have used the knives about every day for the past 2 weeks and so far the are great to use. Very comfortable, super sharp and they clean up well. The only issue I have had is the Scissors come apart very easily, I've had them fall apart while using them twice already. I will see about adjusting the tension on the connection, but honestly the scissor is not very important to me and I don't mind replacing them with higher quality kitchen scissors if need be. Overall we are very happy with this purchase and I expect that with proper cleaning these knives will last a very long time.

Forged Knives at a Stamped-Knife Price
Size: 18-Piece, Style: Traditional Handle Design
Purchased as a gift for a friend suffering with an old, rusted, chipped set of cheap big-box knives. As far as I can tell, these are one-piece forged/milled knives with a full tang... no idea how Amazon gets them so cheap. I have a set of J.A. Henckels Four-Star that were 5x the price, and these knives are almost as nice in fitment and quality. Some of the grinds at the bolster aren't quite symmetrical, but nothing that functionally affects the knife. Not show-dogs, just old reliable mutts that get you where you need to be. Knives have a good weight and balance, not too heavy but sit well in the hand and have a nice action. The edge out of the box is only average, and the chef's knife had a decent roll to the edge out of the box. However, they sharpen easily and can take a fine edge with a little work with the steel (no word on edge longevity yet, they don't cook that often). The shears come apart for cleaning (which is nice), although I found it a little too unstable when opening them wide, the rivet is at 90* so when taking a big bite they have a tendency to come apart rather than scissor. Changing to a design that doesn't separate until they're fully open would make them much better. The woodblock is pine, and had a distinct pine scent out of the box (I suppose this is an area where they saved money, I would pay a premium to get a bamboo block instead). The exterior was well-finished, but the interiors of the knife slots did have some rough spots and/or splinters from the milling. Nothing that stops it from working as intended, a little back and forth solved the majority of problems. Friend hand washed them after receiving them, but left them damp. Water spots, but no rust on any of the blades, the steel had light surface rust that came off with a scrubby sponge and soap. Overall I remain optimistic they will stand up to the abuse of a forgetful cook. Having bought expensive German steel, and now these, I daresay I would probably be unable to tell the difference between the two in the kitchen.

This is an inexpensive quality knife set!
Size: 18-Piece, Style: Traditional Handle Design, Size: 18-Piece, Style: Traditional Handle Design
I have been a Chef for 17 yrs. and from experience know you don't get quality in an inexpensive knife set. This AmazonBasics Premium set really impressed me. The knives I use and have at home are mixed matched because I like good hefty knives. My wife always rags on me that the knives look crappy, so I got on here and started reading reviews. I was not gonna spend alot of money on a set knowing that I have good knives already. Then I saw this set, and looked at the video. I got them in TWO days, and when I opened the package I was expecting the block to be split, chipped, or have saw marks. As you can see the one I got was flawless. I then took out the chefs knife and smiled. Easily comparable to a 8" Zwilling JA Henckels Pro Traditional Chefs Knife. It has the same quality, heft, and balance. TRUST ME I KNOW!!!! Beautiful knife. The thickness of the blade is equal to my Victorinox Fibrox Chefs Knife and I paid $45. for that knife alone!!! This here is a quality product at a good price. Treat them with respect and they will last for YEARS. If your looking for a good complete set, a nice wedding gift, of just looking to replace the "crappy" set you have look no further.

Amazing for the price
Size: 9-Piece, Style: Traditional Handle Design
At a higher price they would have been 4 or 3 stars, but for $50 this is an insane deal. The steel is pretty good quality. It almost seems like it's hardened VG-10 but I think they would advertise that if it were so I'm guessing it's a cheaper stainless steel that just comes harder without being treated though I'm just speculating based on price. Anyways they're flat ground, take an edge easily, and hold it reasonably well. Nicer knives would certainly hold an edge longer but I'm pretty happy with them. The flat ground shape of the blade is actually ever so slightly convex as well, it's not too apparent in use but you can certainly see it in the reflection. The serration on the bread knife is the inverse of what I would prefer, rounded metal with points cut into it vs points extending from the blade with the rounded parts cut out. When the rounded parts are cut out it's easy to sharpen. When the points are cut out it's almost impossible to sharpen. The handles are the downfall of the knives. They're not smoothly finished and while they look alright they feel like a cheaply cut (although very solid) piece of plastic which is exactly what they are. A little bit better finishing on the handles would really improve the knives. The holding block serves it's purpose well. The sharpener is ok but below average, though the rough steel rod sharpeners just aren't great to begin with. Diamond coated rods are much better, though ceramic rod sharpeners are the best. Overall I love the knives and I'm glad I bought them. For the price they're the best deal I've ever found, no question. I love that there is no logo on them, but I just don't like to see branding in general even if it's a premium brand. If you're buying this for the bread knife or the sharpener, don't, they're not good. If you want the look and feel of a $300+ knife set, don't buy this, you'll be disappointed. If you want a good quality knife set but aren't willing to spend $300+ then absolutely buy these, they're great.
