Growing tomato starts with the FGI Square 2

 The FGI Square 2 is an excellent entry level LED grow light for those looking to give their plants the sun's energy. Unlike other lights on today’s market that only provide certain colors needed by plant life (or lack thereof), this one provides all the necessary components: red, orange, yellow green and blue spectrum which together make up the building blocks for successful photosynthesis (and closely matches our sun). 

If you are looking for an easy to use LED to learn how to grow any plant types indoors, look no further than the FGI Square 2. Well loved by gardeners everywhere. Designed in the USA by Forever Green Indoors in Seattle WA. Plant lighting LED light experts since 2013.

Use the Square 2 to grow all types of plants. Placing the light closer to the plants provides enough energy to match the summer sun. Pulling the light further away, or using the built in dimming, provides the right energy for starts and seedlings.

The right kind of light can make all the difference for your plants. Flowers, fruits and other high energy use types require levels as high as 1000 PPFD - a measurement that approximates natural sunlight.

Spectrum From Our Sun

 

We design grow lights to closely mimic natural sunlight (shown above). Although it's not possible to exactly duplicate a giant burning ball of hydrogen, we get as close as possible with the Square 2.

Happy hound!
Color: Yellow, Color: Yellow
My 2 yr old bloodhound destroys every toy in minutes, but not this one. My husband and I actually buy toys to see how long they last for fun. Although the croc is NOT indestructible, it lasts a whole lot longer than most. After an hr or so, I took away the only piece he's chewed off which is part of the back leg. Otherwise nothing else is missing off the croc. Our boy has been very occupied with this new toy and we're satisfied with his new distraction!

Definitely a tough toy
Color: Blue
This is one of the few toys my Boxer/american bulldog mix hasn’t been able to tear apart. He loves chewing on it and I love that he doesn’t chew on stuff he shouldn’t. I have such an issue with toys being torn apart the day I bring them home. I wish there was a safe way for it to have a squeaker since he loves squeakers but I don’t think that is possible.

Croc-sational
Color: Blue
My tough chewer is OBSESSED with Croc. Stands up well, small particles occasionally come off but this beats going thru 3 stuffies in an hour. Good value, easy to clean and great for our 91lb pitty

Good for a few weeks for large dogs
Color: Blue
It held up for a few weeks. The arms and tip of the tail were chewed off. Had to throw it away so my dogs wouldnt eat the parts that they chewed off. It kept them busy for a while.

Dog likes it, but is very hard material around smaller dogs when he is playing and running
Color: Blue
My 22lb dog loves this chew. We have owned it just for one day. He immediately loved it and he races through the house holding it in his mouth like a grand prize. I have concerns to the hardness of the ends of it, the material is very hard, and the tail comes to an end shape that could hurt other pets in a multidog home if it hit or stuck in them. I have two smaller chihuahua dogs, one who has lost an eye so this is something to be careful about with other dogs running with this toy. This may not affect a one dog home. Best to observe the dog while playing with it around others.
