Keif's Micro Medical Cabinet

[Keif]

Hello everyone!

First off, I want to thank everyone on ICMag for everything they have contributed!

I have been a reader here for at least 3-4 years now.

This is my first grow journal and my 5th grow ever. Dont get me wrong though, since I have done 5 grows, this is by far the best cab that I have made and I actually am doing things right this time around!


Specs:
Cabinet from Target
Noctua 120mm PC Fan - Exhaust
Passive Intake
Mylar on walls
Sunsystems reflector
125w CFL - Veg
250w CFL - Flower
Adjustable Pulley Light Hangers
FFOF
Rootech Cloning Gel
Fox Farm Nutes


Plants:
1- Master Kush Clone from the local dispensary
1- Skywalker OG Clone from local dispensary
Soon to be cloned into more clones


Now, I have just moved to LA from the East Coast so I am giving my go at some store bought clones. I was told the MK is easy to grow and the Skywalker will be more of a challenge.

Right now, I am not sure what temps are but I am guessing 75-80, it is much much cooler than my old cab that was running at about 85.

I have spent time researching components while building this cab so it was done over the course of a few weeks.

I just have put the clones in on 10-2-10 and that is what I call Day 1, so follow along below, I could use your input, especially on the Curling Leaf image!

Cab:

Inside:

Day 1:

Master Kush, Notice the deformed leaves (this is how I purchased it)

Day 2: LST started

MK:

Day 3:

MK- WHY ARE MY LEAVES CURLING LIKE THIS?!?

Skywalker OG, finally perking up!

Day 4: MK Leaves are still curling and starting to yellow- FFOF?? I also topped MK today.

For the leaf curling issue, I believe from what I have read, that it is a PH issue with my tap water.

I have started using Bottled water as of today (Day 5) and will post pics tonight.

Thanks for looking!

The leaves are not yellow like the look in the pictures, must be lights? Sorry about that.

Also, the leaf issue is that they are curling like "taco shells" 1 leaf on the MK is turning yellow around the edges but that is the only one with this issue. --PH maybe?? I changed the water up today so we will know in a couple days. Also, I think it could be due to FFOF being to hot for the clones at first. I ran into this issue with FFOF last grow with my seedlings.

Let me know what you all think!

Day 5 Including Leaf Problem:

The problematic leaf:

Now that is the only leaf showing the problem to this extent. Even leaves lower/higher are not yellowing nearly this bad and usually I see the problem work from the bottom up..

Hopefully the new non-tap water will fix this issue!

Hi Keif,
I dont see your pics...on firefox/xp...would love to help.

OO

 

[Keif]

Sorry! I think it is because my album is private, let me make it un-private and refresh!

 

[Hammerhead]

I see tip burn. Soil is to hot or your feeding to much

 

[Keif]

Havent fed, must be the Ocean Forest... I am sure she will get used to it.. I thought at first it could possibly be PH from my tap water. I watered today with bottled water, so we will see if that changes!

Any clue on the "tacoing" of the leaves??

Thanks for your help +

1.Too much marijuana fertilizer
The most common cause of marijuana leaf cupping aka leaf margin rolling, leaf margin burn, and leaf tip curl/burn is overzealous use of marijuana plant food. In relationship to factors such as marijuana plant vigor and rate of growth. Leaf burn is often the very first sign of too much marijuana fertilizer.
A hard, crispy feel to the marijuana leaf frequently occurs as well, as opposed to a soft and cool feel of a happy pot leaf. Back off on the amount and/or frequency of using marijuana fertilizer. Too much marijuana fertilizer can also burn the roots, especially the sensitive root tips, which then creates another set of problems. Note - as soil dries, the concentration of the remaining salts rises further exacerbating the problem.

2.High Heat
The marijuana plant is losing water via it’s leaves faster than what can be replaced by the root system. The marijuana leaf responds by leaf margin cupping or rolling up or down (most times up) in order to conserve moisture. A good example is reflected by the appearance of broad-bladed turf grass on a hot summer day, high noon, with low soil moisture levels - the leaf blade will roll upward/inward with the grass taking on a dull, greyish-green appearance. Upon sunrise when moisture levels have returned to normal, the leaf blade will be flat. Lower the heat in the marijuana grow-op and concentrate on developing a large robust root system. An efficient and effective root system will go a long way to prevent heat induced pot leaf dessication or marijuana leaf margin curling. One short episode of high heat is enough to permanently disable or destroy leaf tissue and cause a general decline in the leaves affected, which often occurs to leaves found at the top of the cannabis plant. The damaged pot leaf (usually) does not fully recover, no matter what you do. Bummer in the summer. One can only look to new growth for indications that the problem has been corrected.

3.Too much light
Yes, it’s true, you can give your marijuana plant too much light. Cannabis does not receive full sun from sunrise to sunset in its natural state. It is shaded or given reduced light levels because of adjacent plant material, cloudy conditions, rain, dust, twilight periods in the morning and late afternoon, and light intensity changes caused by a change in the seasons. Too much light mainly serves to bleach out and destroy chlorophyll as opposed to causing marijuana leaf cupping, but it often goes hand-in-hand with high heat for indoor marijuana growers. Turn down the time when the lights on in your marijuana grow room. If you're using a 24 hr cycle, turn it down to 20 hrs. Those on 18 - 6 marijuana growth cycle can turn their lights down two or three hours. Too much light can have many adverse effects on marijuana plants. Concentrate on developing/maintaining an efficient and robust root system.

4.Over Watering
For marijuana growers using soil, this practice only serves to weaken the root system by depriving the roots of proper gas exchange. The marijuana plants roots are not getting enough oxygen which creates an anerobic condition inducing root rot and root decline with the end result showing up as leaf stress, stunted growth, and in severe cases, death. Over watering creates a perfect environment for damp-off disease, at, or below the soil line. Many times marijuana growers believe their cannabis plant is not getting enough marijuana fertilizers (which it can't under such adverse conditions), so they add more marijuana fertilizers. Making the problem worst. Not better. Often problem 1 and 4 go together. Too much marijuana fertilizer combined with too much water. Creating plenty of marijuana plant problems.

5.Not Enough Water
Not only is the marijuana plant now stressed due to a low supply of adequate moisture, but carbohydrate production has been greatly compromised (screwed up). Step up the watering frequency, and if need be, organic marijuana growers may need to water from the bottom up until moisture levels reach a norm throughout the medium. One of the best methods in determining whether a marijuana plant requires watering is lifting the pots. The pots should be light to lift before a water session. After watering the marijuana plants lift the pots to get an understanding how heavy they've become fully watered. If the pot feels light to the lift - it’s time to water. Don’t wait until the soil pulls away from the side of the pot before watering. And of course, leach, once in a while to get rid of excess salts. These are the five most common problems marijuana growers encounter when growing cannabis. Correcting the problems early will save the marijuana plants, but may reduce overall yield. With practice and experience these problems are easily overcome which will then enable the marijuana grower to produce fantastic marijuana plants. With heavy yields.


Hope this helps

Holly shit man! Great help! Thanks so much, I think maybe there is not enough oxygen at the bottom of my pots!

Thanks for the help!

Hello everyone!

Just wanted to give you all a little update from this past weekend!

First off, I have finally gotten a thermometer and temps were at 92 AHHHH. This is more than likely due to the ambient in the room being about 80 or so with the windows open..

I drilled 2 tiny new passive holes as well as bough a fan that can be run and blow on the plants.

Temps are now 85 degrees... Still not good enough. Any tips on how I can improve this? I was thinking about drilling another 8 or nine passive intake holes in the bottom of the cab, but not sure if this will help too much. I want to be able to run my 250w CFL but now these temps are so high with just the 125w. I need to lower these ASAP.

My exhaust is a 120mm fan so its about 4.5 inches or so, if that helps with aiding me.

Anyways, the ladies are looking good! I started LST on the OG and the MK is still bushing out! I did her second tie down on Saturday.

I also clipped a small clone from the MK on Sunday.


Day 7:


Day 9:



Thanks for looking!

 

[micro420guy]

try taking the Mylar down and painting flat white. Mylar will reflect heat as well as light.

 

[Keif]

Thanks for the tip, however I do not believe this will get rid of ten + degrees of heat.

The mylar, as shown in the top pictures, are just on the side and half of the back/front.

I am going to try some more holes in the bottom, and then if this doesnt work, I will have to go ahead and paint the inside white.

Thanks so much for your help..

 

[Struckanerve]

i would suggest, a better fan for exhaust or maybe add another. Also get a small desk fan have it blow on the light. Or just hang a cpu fan infront of it. Should help with the temps

 

[Keif]

Is it possible to stack two of the same fans on top of eachother for exhaust?? I am going to see what drilling more holes will do to help.

Thanks so much for the help! ++rep

Hi Keif,

Yes, you can stack fans but not directly. They need a 1" or so spacer between them. An old fan with its guts removed works well. See my sig for a great fan thread.

How tiny are these holes? The area of your intake must be about double that of the exhaust. That fan thread will tell you everything you need to know.

Nice looking girls,
OO

 

[Keif]

Thanks oldone! I will check out that thread. My cab has been running at 85 all dsy. Not HORRIBLE.. I have been thinking of modifying my hood as it takes up a large portion of room, not allowing the air to rise out. How does that sound?

Sorry,

My last post was from my phone and I seemed to have missed some of the questions you asked.

The holes are 1" and I have about 12 of them now. I did some calculations and I think I need to add a bunch more. I am thinking of making a tray that sits of top of the holes in the floor, about 1.5 inches higher. This will allow less light to leak, and more floor space available.

I have a few ideas, including drilling a few holes or even cutting a bunch of my reflector apart so air can pass it. I believe that the reflector is acting as a shield and not allowing air to pass as it is almost the same dimensions as the cabinet.

I hope that would help.

Thanks for the suggestions.

 

[oldone]

I think the tray is a good idea. But why not cut a big hole under it. Just that change and see if it effects the temps. Maybe you wont have to do anything to the reflectors.

see ya,
OO

Not too much to say here, the temps are at about 83-85 and I will drill more holes this weekend to get it to the 70's.

The MK is fucking bushy as hell and the OG is starting to really take off!

No signs of roots on the little clone man yet.

Anyways, here are the pics!

Day 11:

You can really tell that the MK is bushing out like crazy after my top/LST.

OG just got tied down for the second time, lowering the temps really made her start growing

 

[Keif]

Today (Day 12) everything seems to be going great. I cant believe how much that OG clone is stretching after getting the temps lower.

Temps are about 83-85 today- this weekend I will be doing the overhaul to get them into the 70's.

Keep in mind, these plants are about 3-4 inches tall. The MK clone is SUPER BUSHY.

Day 12:

Day 12 MK:

Day 12 OG:

Thanks for stopping by!
