Brussels Sprouts

[duajones]

First time grower, dont even know the variety as the local nursery just had them tagged "brussel sprouts" and didnt know what they were. Anyway, they are at the 102 day stage and are in a spot that I will need come Late February. The sprouts on the plants now range from pea to marble size. I have read where you can cut the top off of the plants and the sprouts will mature quicker. Should I do that now or give them another 30 days?
