9-29-09

Temps 79 res 68°
PPM's 580
PH 6.0

They used about a gallon of water, Left the res alone.
Cleaned up some lower leaf, funny not any yellow leaf, sure the stuff that was dying from lack of light but
no deficiencies I could see. I got a few handfuls.

Here's a shot from underneath;

The floro cab just started week 5 of flower.
I skipped week 4 and five in ff feeding and went right to there week 6
so we might run a bit shy on nitrogen but I really didn't want the size.

PPMs 600
PH 6.0

A few bud shots;
Widow

Kush

Train wreck

The kids

The Cabs,

I read stinkbuds journal again last night, funny never read it all the way through. I just went there to see his hydro design.
Anyway I like his flushing technique. I am going to try some clearex. Its a salt leeching solution to help remove the
remaining nutrients. I flush for 24 hours with that and then flush with Ph 5.8 water.

Placed an order on ebay last night, got an email today, its in the mail.

Looks delicious buddy.

One question, I meant to ask you a long time ago, but where did you get those little fans? I keep looking for them online and can't find any. I know they don't oscillate, but I feel like they are still a much better idea for my grow

 

[cruzer101]

Hey Tm,

Yea, The train wreck is going to be real tasty, I am not sure about the Widow though.

Those little fans are awesome. I think I got five of them now.
Real quiet and for there size, I dont they make one that pushes more air.

Anyway, I found them at wallmart dude. The brand name is Massey.
There are different sizes, this is there 4 inch. $10

lookin great cruzer just following along

 

[cruzer101]

Cool man,

You will be able to see for yourself what t5's can do in flower.
I got three 3000k and one 6500k in the hood. The CFL's are 18 watt 2700k

 

[tehnick]

took a while to go through the thread, but worth the read. i'm a new medical grower for myself and am trying to figure out as much as i can. i'm fixing to flip the switch to flower on sunday. seeing threads like this have been a big help man, thanks a bunch. i'm hoping to try and find a cabinet like yours for a separate veg and flower area. i'm a soil guy tho since i had some real hardcore problems with hydro. maybe i'll try it again at a later time.

 

[cruzer101]

Hi Tehnick,

Glad to help. Those meds can be expensive at the clubs.
Gonna flip them sunday huh? Good for you.

Nothing wrong with dirt man, fewer plants bigger colas indoors. have you checked out montana med grow?
GTO he just cut like 12 ozs and hes in dirt. Awesome job.

good luck to ya.

 

[phreakygoat]

fantastic progess with the T5s, its great to see kush show her true colors.
the grow is at its climax right now, with cabinets absolutley stuffed with sticky plant matter!
has life been easier for ya with that scrawny WW removed a while ago?

 

[tmsculli]

Cruzer, I can't find those dang fans man. Online they run 20$ a piece =/ I guess I will have to suck it up. They are exactly what I need.

 

[cruzer101]

I guess you didnt see my reply,

I got them at wallmart, 4 " Massey fan $10

Yea I think so,
That runt widow was on the right side and thats where I have most foliage. left side is cool though.

This was a trial grow, I wanted to max the cab out to see what I could get with monsters. Now I look under there and see lots of half developed buds. Make me think less is more.

The other thing is I do not have proper reflection. I am working on a new reflector to maximize the lighting. (no not oven liners)

Stainless steel ducting spread apart. sounds weird but looks like it will work great. I got the idea from tnsculli's journal.

 

[cruzer101]

OK,

Got the clearex today, I drained the res, filled it with tap, (yuck) ph it to 5.8 and ran it for an hour to wash it out, drained res. Then I refilled with 1/2 tap and 1/2 r/o cause my water is so shitty, It came to 220 ppms.
Then I added the clearex and ph to 5.8. After an hour the ph jumped to 6.5 and I left it at that. Stinkbud didnt say anything about ph on this part but I thought what the hell.

So, I will run this for 24 hours then change to fresh (1/2 tap 1/2 R/O) and finish up in about a week to 10 days.

Do you have a link to this? I tried searching on the username, but couldn't find it.

Thx!

Hey DB,

Well its work in progress,

I looked at the current shit I have for reflectors.

I am missing that mid area and what I want is a reflector thats the same shape as the light. But I want side lighting so I wanna build it into the thing.

I went to home depot, the ducting section and found sheet metal but the sizes were to big so found this 8" ducting thats 36" long. When I measured it flat it would be 24" so I got it for $12 and a couple aluminum strips $5 ea.

I had a couple of those welded wire frames for signs you stick in your lawn so I got those and cut them to prop the thing open.

I trimmed off the bottom

Then cut it in two, one for each side and weighed them because I want
this on yo yo's and they only hold 22 lbs.

OK 4 and 1/2 pounds so far.


Heres the idea,

Thats 42 inches wide right there. I am building it on a table in front of the cab to check size.

Now I am building braces for them out of the aluminum sticks.
This is my first attempt. the sticks hold the weight no problem.

I notched the aluminum for the wire and the hood. set it on them and picked it up by the sticks. Works good.
So now I need a frame for the top and hold the tube. Like an A frame.

So thats where I am at.

I wanna mount the CFL's at the edge of the wing and be able to move it all at once. Kinda crazy I know, I will probably end up shorting it. Maybe with this much reflection I wont need them.

I plan on cutting in a week or so, I'm gonna fix the ducting and try it then.

I would not recommend a long clearex flush.

A couple of hours is plenty to wash the salt off,
and you will get tip burn when you re-introduce nutes,
unless you start the nutes low and bring them up slow again.

DYNAMIC NATURE OF ION UPTAKE

1. Regulation at the uptake step: CaSO4-grown plants

In the 1930's and 40's Hoagland, made use of barley seedlings grown hydroponically for about 1 week in solutions containing only 0.5 mM CaSO4 to measure the uptake of K+, NO3-, and other ions.
At a time when measurements of ion uptake were generally made without the advantage of radiotracers,
it was necessary to optimize uptake or be satisfied with experiments that lasted for days,
and therefore suffered from lack of sensitivity.
Hoagland observed that growing the plants this way
compared to growing them in full nutrient-solution,
considerably increased the rates of absorption of all ions except Ca2+ and SO42-.

Actually, the observation was recorded as early as 1906 by Brezeale,
who demonstrated significant increases of nitrate, phosphate, calcium, and potassium uptake
when these ions were removed from the media for 15 h (table 1).

Thus, it would seem as though the plant adapts to the absence of a particular nutrient
by increasing the capacity to absorb that particular nutrient.
(To read the full report, click on the above paragraph)

So, what happens is,
once deprived of a nutrient for more than 15 hours,
the plant will attempt to take up too much
of that deprived nutrient,
and it will burn.

 

[cruzer101]

Hey Earl,

Thanks for the info.

I already ran it for 24 hours then drained it and filled with tap/R/O water with a ppm of 150 at 5.8 Ph. My guess is the plants will try and absorb nutrients but there wont be any and they will use up there stored nutrients. Does that sound about right to you?

It sounds to me like it wont matter if there are nutrients or not in the res. They will still burn themselves. Did I understand that correctly or will there need to be nutrients in the res for the burn to happen.

At this point I am just trying to flush the nutrients out.

 

[Earl]

If you are at the end of the grow then a long flush is good.
2-4 weeks if you have the patience for it.
I thought you were doing flushes between nute changes.
If you are bringing it back at 150
I would stay near that number
until they finish
and then do a RO only flush
before chop.
I wouldn't go near 300ppm, for sure.

 

[cruzer101]

Gotcha, I thought that might be the case.

Thanks for the info though,
I was planning on using it during the next grow and now I know what happens so I will do 12 hour cycles. Good to know.

 

[cutman]

Hey buddy looking good. Nice little buds, how big are them colas at the top, and how is the dream team? Its been a while. That took a while to catch up on your grow. I chopped two of mine, out side, they are in jars now.Still have one blue berry out there going to let her go a bit longer but she looks done, smells allosome. I started 3 hawaiian snow babys and 5 ak47 x lr2 autos last week, although i dont know why. i have enough to last me till next year easy.lol every body wants to buy some, but i dont sell.lol i bought a vacuum sealer and package it all up. i did 1 auto, 5 weeks ago and she looks nice, shoot u a pic tomorrow. need batteries.

 

[cruzer101]

Cutman, good to hear from ya bud.

Yea, I'm just cruzin along, Had an issue with a neighbors gardener, we think he may have seen the Dream Team.
We are just not sure so we cut the widow early it was stinky widow and smelling up the place. The Super Silver Haze
is still growing though, probably another three to four weeks. Long colas bro, like 18 to 20 inches.

In my cab here I am about to cut. I guess the big buds are about banana size and a lot of golf ball size underneath.
I got one Widow that will be real fat.

So that auto is kickin ass huh? Yea I would like to see her at 5 weeks.

Get rechargeable dude, two sets and you never run out.
