Microcosm - 2nd Seedrs crowd-funding round

Current schedule:

29th/30th July: Shoot and edit video
1st August: Edit pitch text and submit video and text for verification and fact-checking
8th August: Launch to existing investors
22nd August: Launch publicly

Does that mean existing investors have a two week window in which to either maintain their current level of investment or increase it?

I ask as I'll be on holiday on the 8th and might not have internet access until the 11th and I don't want to miss out.

Thanks.
