Thanks ijahdan, your plant look pretty beautiful. Reminds me of my bigger icaros. Now that I see it looks like you grew it from seed but not bought it as a seedling. My plant was a bit shorter than yours when I first got it. 6 inches in 3 years from seed under the conditions you described does not sound too drastic but do move them under a sunnier spot if you have the chance. Their growth rate is more or less exponential until maturity so I bet it will be able to celebrate your 50th with you. Keep giving love to them and they will love you back
