Advice on when to harvest

Hi there

Seeking advice on what to do with this not so little lady.
Im going overses for 2 weeks in 5 days time so the question is whether to harvest in 4 days or to just place this lady by a window and let her finish off for another 15-16 days. She been grown under as 150 watt HPS to date, so I am womdering whether putting her in shielded light (i.e behind venitian blinds) whilst I am away would be worth it. Will she keep growing under weak natural sunlight or am I better just to harvest in 4 days time. I dont want to keep the light running with nobody home. BTW i put her under 12/12 on 2/4/2007 so shes only 34 days in; she is an F1 grown from a cross I made from unknown but potent bagseed, appearance makes me think she has a sativa x indica hybrid pedigree with an approximate 60/40 on the sativa side so I reckon shed tend to run her all the way to maturity at around 60 days.

Can i take her from under the lights for 14 days and then place her back under the 12/12 HPS until she finishes? I havent done this before so I dont know if the change in regime will fuck her up. Obviously as I only have one plant I am looking for max. yield.

Hope one of you kind n knowledgable folk can help me.

Cheers

how do you plan to water it?... and that LOOKS like a good 10-13 week finish..

looks pretty strongly sativa to me, more than 60% i'd think; might very well be 100%; maybe some outdoor mexican field weed

man tough decision i would definitly keep it there by a window but who knows, it could die. i think that plant could get so much fatter

Better to harvest early and sacrifice yield than leave her alone and possibly come back to a disaster. Just my two coppers.
