Thanks everyone for all your replies.
Ice cream bean sounds interesting!
I grow everything in a pot, and it is under lights 16 hours a day, 77 -89 , 40-60% hum
I have just started growing under T5 lights since September.
I have yet to add the red spectrum, because everything is still very young, 1-3 months.
Jackfruit is way faster than anything else I have
Haden mango, sweet Tamarind, and Jackfruit( unknown variety)
I did mean fastest growth , not fastest to fruit.
I love to grow , and watch plants grow, so, the faster, the better.
I happen to be a "plant person" , need 6 hours of sun a day, or I feel ill.
I also love all tropical fruit, so its a no brainer why I go crazy for fruit trees from the tropics.
It would be awesome if something fruited to maturity, but I cant see why it would taste any good, plus it would be impossible for me to keep Rami from touching the fruit, he is trained not to steal it or eat it, unless I give it to him. He has very dirty hands.
