Thank you for your email. I am sorry to inform you that we can not delay the shipment to week 7, the total delay of 4 weeks would be to much for the plants they will deform in the trays and it would not be good for the quality.
Please note we need these requests earlier as the plants are already separated to prepare for shipping with an adjusted watering schedule etc .
If you like any adjustments later in the program I can check the possibilities, like delaying the shipment in week 7 with one or two weeks as these two shipment are more close together then the other shipments.
