I used to rock a 1 week flush. Then I tried the HH/
MOAB combo as recommended with a 2 week flush. Always with drip clean and enzymes.
I will never run a 1 week flush again after smoking the 2-week flush weed.
It is really something I would recommend if you have not tried it yet.
I am talking about a 9 week strain in particular, topfed coco/perlite mix.
2 week flush weed, when it turns out right, is more than 2x better than 1 week flush to me.
But maybe others in different media with different nutes can get away with less flushing and maintain the super high quality.
The temptation of an 8 week strain is to not flush for 2 weeks. So I had to start growing 9-10 week strains.
