That maxi mini was about 6", I had it about a year. It just kept growing and never split. I made the mistake of cutting into forths. I lost 2 quarters. Flow is extremely important. I had my korollia aimed directly at the basket they were in. I made the mistake of plugging it into the light powerstrip, it went off at night. I have cut many, aside from this stupid mistake I have not had any other losses. My advice is try one, one of your less valuable colors. Make the cut in two strokes, mouth out, one side than the other. The maxi minis will take a month to heal completely while the minis will heal in a week. Good luck :thumbsup:
