I have gone both ways,
and now I have to flush for
at least a week of RO only.
I use a method like Earl's. I use Clearex for the first 24 hours and then tap water for the the rest of the flush. I time it for a 2 week flush. I go longer if needed.
My tap water is 200 PPM @ 7.1 Why not RO water? I'm too fukin lazy. I already change the water every couple of days during the flush so fuck it. I just take another bong hit and try not to overfill my res like an idiot. I used to adjust the ph during the flush. Then I figured WTF the plants aren't getting anything out of the water anyways so I just leave it at 7.1 and it works fine.
I learned my lesson about flushing 14 years ago when I used fish emulsion right up until harvest! The plants grew like crazy so I thought what the hell. I still remember the fish like taste of the buds. Nasty as fuck! They tasted like butt! Fish butt. The debate on flushing ended right there for me...
I prefer a little more head buzz so I time my flush so that the buds will finish at peak ripeness. My AK47 has a real nice Sativa like high when harvested at 67 days. My Blueberry on the other hand is a little on the ripe side at 67 days but the flavor is better. The high is more Indica like also so it works out well for me. I have a nice Sativa for the day and a super dank Indica for evenings. Both finish in 67.
Earl you got it right about commercial weed. It's hard to buy epic weed here in the States. You have to grow it yourself.
Commercial strains are all about making a profit at the expense of quality. Commercial growers need to turn their crops fast. They can't have massive amounts of weed sitting around curing for months. They can't afford to have long flush times because they need to bring in the next crop. Many of the younger generations have only smoked Indicas their wholes lives and have never even tried a nicely cured Sativa. Sad but true...
I have a new strain I'm trying now that's just about to finish. It's called Tutti Fruiti. It smells just like the name! I sampled a little nug and it seems like it might be worth keeping.
I'd like to find a good old school Hawaiian skunk with a decent finish time. You guys know of any?
