going away to college...need some help with when to harvest

So guys here the deal: Im going to college the 21st. My friend can water my plant on the 23rd as the last day it can be watered. I plan to come home the 4th or so of october to harvest. I dont know if aqua globes will work for this situation. Would it be bad to let the plant dry out a little before harvest or do you think it will ruin the quality of the bud? Peace and

watered on the 23rd harvested on the 4 ...you'll be fine ,plants will be fine!! make sure he gives them lots of water!!

it wont hurt them if they dry out right before harvest!
