I'm a new member and new to indoor hydroponics, I have grown summer hydroponics gardens for years outdoors in Bato Bucket systems but I just set up to do the indoor year round grow thing. I purchased a Volksgarden system and equipped it with a 400 watt HID light to grow my leaf vegetables, it grows up to 80 plants with a 4 foot by 2 and a half foot footprint so for space it's hard to beat.
I have noticed with my first planting that both my arugula and my spinach have grown leggy and bolted after less than a month in the system. Is this from too much light? The volksgarden light is in a glass cylinder and a stream of air is sucked past the bulb to keep it from getting too hot. The daytime temperature is about 70 degrees and the night temp cools to 65.
Any input will be appreciated, as I said I'm new to the indoor garden thing and eager to do this right.
