question on lager starter

[megavites]

I'm brewing a Vienna lager on Sat. with WLP838. LHBS was only able to get
1 vial of yeast so mrmalty says I need a 4.76L starter which translates to
16.9oz DME to 158oz water for a 1.040 starter.(about 1.32 g of wort)

Should I go ahead and start this tonight in a 5gallon better bottle?
IF I use my 2L growler I would have to step up 2 times.

Is 5 days enough for a 2step starter along with cooling?

No problem using your BB (I assume no stir plate).

5 days should be enough to step up twice. If you have a stir plate things move along a little faster. If not you can always use the better bottle for your starter.

no stir plate yet. I decided to go with a 2L starter and step it up.

The first starter should grow 200 billion cells for a total of 300 billion. That would be a fairly high inoculation rate for the second step. (150 million per ml) That's in the verge of causing issues, but not too high. You should have 500 billion cells when completed.
