400w MH/HPS multi-strain ScROG First grow!

Highocaine · May 31, 2013

Up the ante on the air movement - I have a 6" duct fan, cheap can fan, really.. Within 24 hours of installing it (from nothing), my RH dropped 20%, the droplets in the corners (underneath the tray) went away and the RH inside and is now lower than the RH outside my tent. That said, I live in a dry area and it only took 60% RH to have condensation form. Temperature difference matters too, a heater at night would probably help.

Apart from that all you can do is dehumidify or use DampRid.

Was that a 6" canfan for intake or exhaust or just movement in the tent?
Because right now I'm passive and the humidity outside the tent (inside the room) isn't much better with the window open or not, winter started this month and there's been a lot of rain.
Temps have been around 17/18 lights off and 21/22 with lights on. Not perfect in their values but the difference between day and night is pretty good right?
I briefly thought about removing the glass cover, then realised it's sealed and my filter is on the other end so that would be counter productive.
The glass on the hood is wet at lights on, the leaves love growing into it.
Couple of pics, we are at day 22 of 12/12 for those playing at home.

It's exhaust only. No idea on the CFM. Lookin' good regardless though! And the temps seem pretty good.

Stormy111 · Jun 3, 2013

Going to transplant clones tonight into 450ml party cups where they shall live under a couple of 23w cfls for the next 6 or so weeks.
Checked yesterday and 12/12 have rooted, very happy with my first attempt.

Stormy111 · Jun 6, 2013

All transplanted!
Went into the hydro shop to get some more cocoperl, scored a 1 litre free sample of some general hydropnics fruit n fusion so I'll be using that for the rest of the grow.
Plants are well and truly into flower now, some nice buds forming!
Recalibrated my pH pen, it was reading 0.4 units out so my 5.8 was really 5.4, no real damage.
Definitely regretting not training further into flowering and better to begin with, plants are almost 16" above the screen now, I'm thinking of going two plants next time for easier reach/training. Don't have that many tops but what I do have I'm hoping will be quite dense, I really would like 0.5 gram per watt.

Stormy111 · Jun 12, 2013

Buds are fattening up nicely!
rh seems to have stabilised nicely under 70% with a tub of damp rid, hopefully keeping the air movement up should prevent any rot in the coming weeks.
Also raised the light to stop the leaves causing too much condensation.
Feed schedule calls for a week of pk 13/14 so that will go in tomorrow and I'll feed at a slightly higher ph (5.8-6.0ish).
Pics to come this weekend.

Stormy111 · Jun 14, 2013

Few pictures.
Taken day 35 of flower... how does it look like I'm tracking as they're all unknown strains, 8 weeks or 12 or somewhere in the middle or is it too early to tell?
Cheers.

Stormy111 · Jun 20, 2013

Getting very nice and frosty, handful of pistils are turning amber.
Almost time to top the clones.

Stormy111 · Jun 22, 2013

Few more pictures... these aren't even the biggest buds just what's towards the front of the tent..
Played around with macro settings and flash etc.

Stormy111 · Jun 23, 2013

Heading into the final weeks.

Stormy111 · Jun 23, 2013

Does anyone even read this?
I won't bother with any further journals after this grow is done .

Highocaine · Jun 28, 2013

Aw. I read it! You might have more people read your journal if you put a link to it in your signature, then post around the forums.

The Grow Journals forum updates so quickly that not many people will find your grow via browsing. Some people post their journals in other forums (like Hydro, Aero, LED, CFL, etc) because like-minded growers browse those forums more often.

Still, your progress looks great and I'm tuned in for the finish. :leaf:

Stormy111 · Jun 29, 2013

I figured that might be the case! Cheers.
Before I started growing I browsed a ton of journals and a lot never got finished! Really annoyed me so this one will be finished... I'd post and browse more but between working 40 hour weeks, my girlfriend and working on improving my first home I really don't have much spare time.

Bad news: just culled half a dozen rather infected fan leaves covered in aphids. Made up a 1/3 to 2/3rds apple cider in water solution and sprayed most of the lower parts, I'll hit the top half just after lights out.
I'm in week seven of flower and pistils are starting to turn brown left right and centre!
How long generally between pistils starting to ramp up their action and harvest??? Trichs are still all very clear with a few starting to turn cloudy.

I've definitely found the candidate for the next grow from my clones. The back left plant has some awesome branching and several colas at least 6inch long and half as thick! Very tight node spacing too. However the front left seems to be well ahead in terms of pistil colour yet third in terms of total size and weight. Hmmmm.

Highocaine · Jun 29, 2013

Pistils turning amber/brown is fine that late in flower. Trichs'll ripen slowly.. You can extend the dark period to help the buds ripen faster. Do 8 on / 16 off. Only switch if you're sure the buds won't get any bigger, though.

Stormy111 · Jun 30, 2013

Cheers for that man, I'll search up on altering the hours of light.
Aphids seem to be under control and pistils are nicely changing, trichs starting to turn too by the look of things!

Stormy111 · Jul 2, 2013

They've been on 12/12 for just over 7 weeks now (53 days to be exaxt) the feed instructions allow for a 1-2 week flush for an eight week strain with only cannazyme and cannaboost.
A few of the lower leaves are also starting to die off and yellow so I will not feed again until harvest time, I figure two weeks from today they should be about ready!
Pics to follow in the next couple of days.

Jasper2 · Jul 2, 2013

Its coming along very nicely stormy! I see that you are using cannazym too. Used it for the first time in my second grow. The first one i lost to root rot but this time around i added cannazym and it really is some great stuff! ive read somewhere its only supposed to be used for 6 weeks. DOnt know how legit that statement is but i intend to use it for the weeks to come! im into my first week of flowering and my critical jack is as happy as could be!

Stormy111 · Jul 2, 2013

I just had a quick read of your two grows, nice work.
How long til harvest on number two?

Stormy111 · Jul 2, 2013

Re: cannazyme.
Just following the instructions for feed on the back of the bottle, it's used at 2.5 ml/l from veg state right through to harvest.
For an eight week cycle the first two weeks is a seedling/rooting schedule with no cannazyme so that's where the 6 weeks comes from but as for only using it for 6 weeks I don't think more or less is a problem as I have read if you reuse your coco that you should double the dose to 5ml/l.
However I think it probably works out cheaper to buy fresh coco than it is to pay fot twice the nutrient for it...

I'm probably about 3 weeks away from flipping. Then about 2 months. So late September harvest. Hope I can make it through this hot summer.
