I'm wondering how to go about a pre-harvest flush for my girlz.

I've had a number of sucessful harvests already using a hydro set up. In hydro I do a four day "flush" ,changing the solution daily, or if possible twice daily.

Strains in this harvest are : Big Buddah Cheeze and Power plant. They both list their grow period as 8-9 weeks. Over the course of growing hydro (cool temps) I've found my harvest window to be consistently 60-63 days.

Now, this is the first run of using a soil set up. Using sunshine mix "soil". This round is due to be ripe around August 5th. They are in 2.5 gallon containers.

A) Should I use Clear-X? or just lots of water? Or some pattern of both?
B) How many days ahead do y'all normally switch from nutes to just water?
C) I've been feeding/watering every other day...should I start doing water everyday to help with flush?

D) With my heat levels higher than "normal" and with different medium, should I be more vigalant and checking Trichrome ripeness vs dependant on previous ripeness times? (should I start, have started flushing earlier anticipating faster ripeness with higher heat in grow area) ...temps now are routinely 90-100 degrees.

E) My next harvest cycle, peaking around 3 weeks later, has the girlz in smaller 7x7 square pots (about one gallon). With less "soil", do these take less flush time period...should I continue to feed later into the cycle.

Thanks for replies +/- links

...sometimes there's too much info on here and it's hard to find a simple answer when you don't have 4 hours to research.

Rusty Trichome has a great thread on growing in heat. He says heat causes them to take longer to ripen due to stress. At least a week, if I recall correctly. :stoned:

There is a great sticky on flushing and pH under basic growing I think. It tells you volumes, but generally it is 3 times the pot volume. So, for a 2.5 gal. container, 2.5 x 3 = 7.5 gals water to flush. I believe I've read that you should use pHed water for flushing... but I don't . My plain tap is usually in the 6.0 to 6.8 range anyway. I may change that next grow, for testing purposes.

I've too have had heat issues this summer. In my situation, I also experienced lower yield from known producers, even when I waited longer to harvest. No more HIDs in summertime for me, as I'm just not "efficient" at those temps.

I've had more trouble with flushing, drying and curing than I reasonably should. Sometimes I have residual harshness in my buds that I want to remove, so I have been researching this. One item I found that I missed in previous research passes: excess N in flowering causes harshness. Stinky advised to stop or significantly reduce N two weeks before flushing! So that would be, 4 weeks before harvest, cut the N. Then 2 weeks before harvest, flush soil well with water. No food for last two weeks before cutting.

I haven't used Clearex myself yet, although I have some on hand to try for next grow. As with all preparations, I would use it as directed on the label, until I know what it actually does.

Good luck with your harvest. :jointsmile:

Thanks for the reply.

The largest summer weather problem I've had is in cloning. April and May I was running about 85% sucess on two of my flavors and 33% on the third. The rounds of cloning that I've done in June and July...have sucked!

Last round, about 10 days ago...I was hyper vigelent about cleaning stuff/ throwing trays away and starting over with fresh...and still I have barely any girlz showing roots. Just re-read the "damming" post in FAQ and guessing that I too have had too much humidity and leading to wilt. So we'll try another round this weekend and try to remedy another issue and hope....or wait until October .

I do own a dehumidifier but I don't know if I have the space/ electric to spare to run it right now.

I germinate seeds in September....I don't grow indoors in the summer.

I just have to abuse myself sometimes to prove a point. LEDs only in summertime from here on out.

LED's????...you must live in the High rent district?...

i like to grow six months worth...then quit growing

Yeah, my dehumidifier is a power hog. I hate running it.

Not trying to second guess you but, have you tried adding more fans for your humidity problem? And, if you usually put a humidity dome over the clones, have you tried without the dome?

One thing to consider, I know that some plants only like to root at certain times of the year. If you try at other times, your success rate plummets. I haven't seen this mentioned about MJ, though. This may not even apply to plants kept indoors in an artificial environment. Maybe DP or someone more experienced than I will comment.

Hardly "high-rent". More like sky high electric bill in summer.

I just go with the flow...I can use the extra heat in fall/winter/spring

its nice to be able to grow outside
