Do all new bulbs make a spike?

[irrka]

I'm probably just paranoid, but i've been anxiously waiting for this bulb as it went from 1cm to like 5" already!! There's a bit of a space opposite the leaf (i guess at the junction of leaf and bulb??), so i keep peeking and not seeing anything coming out. Do spikes happen later or do some new bulbs just never make spikes? Do the old ones still flower? ugh.

I think it's getting enough light--it's in a southern window and when i remember i give it some fluorescent lighting during the day to help out (i should just put that lamp on a timer).
