My secret winter garden

[kasvi]

Now wtf is this? It does not show well but there is yellowing between weins. It dont look like magnesium defiency.
I am seriously considering transplanting plants to coco coir.

Straight coco is the best

You have to check ph every watering unless its in range.
This might help:

I did the transplanting of plants in case 2.
I will need to increase my yogurt intake lot so that I get enough cups for case 1.
I use yogurt cup because I can make them self watering and if I have understand correctly 250ml coco equals 500ml soil.


This is how plants are doing in case 1.

I might have acidentaly topped one plant when I was trying to do supercropping so that lower pranches start to grow bigger.
Yogurt cup plant is showing nutrient defiency so I increased nutrietns to full dose from 1/2.

think you might wanna re pot into at least half-litre coco if you want to get more than 2g dry Ive done some in 250ml and got around 3-4g dry.
The one in half litre coco yielded around 5-6g but it was also topped.

you can let em in 250ml and if you top em expect round 3-4g dry.

what nutes are you feeding/ppms?

Did you veg your plants? I see that some people are getting pretty nice plants out of yogurt cups in yogurt cup challenge.
I will veg untill they are all big enough to top, after toppin I will lst and supercrop untill all pranches are on same level and then flip to 12/12.
I want atleast 5g per plant so that I can hit 1gpw.
How often I need to water in 500ml containers?

I feed them GH micro and bloom acording to h3ads instructions. I gave them full strenght solution and they seem not to like it so I gave them half strenght solution which I feed to seedlings. Havent found my meters so I dont know ph or ppm but my yogurt cup challenge plants seems happy. Only little yellowing on first set of leaves before I changed to full strenght solution. So I think my water ph is ok.

I will post pics of induvidual plants on sunday when I do update on yogurt cup challenge.

I want atleast 5g per plant so that I can hit 1gpw.

That's a pretty high expectations for a yogurt cup in a new system. I hope you hit it eventually. My PC plants used to yield 3 grams each and those were closer to 0.5 liter pots. I did hit 7 grams once, so with the right cultivar and time to dial it in you could get 5 grams from a yogurt cup.

It is most likely that I dont get that much but I think it is good to aim high than not aim at all.

yeah 5g per plant with enough veg is not that high expectations but why not run 12/12 from seed? that pc case of yours is not fulltower pc case and you dont want them plants to overgrow lights which is the worst thing trust me been there..

Did you like ever measured your tap ph and what is it at?
after you add nutes it will go lower 0.1-0.2 points just by adding nutes right

Dont want to tell anyone what to do or anything..
but ph is the most important thing when growing all those deficiencies are from bad ph some strains are not that much affected by it for first few weeks but only for those few weeks after more time the shitstorm breaks in /too much trailer park boys has been watched lately.. /.

looking forward for updates..and get proper and calibrated etc. ph pen and ppm pen so you wont be out in the dark with whats going on with the plants.
I was there back in the day not caring about ph and results were all kinds of random shitzorz /not good/.

for watering that 0.5l pots think two times/day is plenty unless temps are crazy high like over 34C less water is better but consistent waterings are what you really want to provide to plants /think auto dripper systems still have to look into those myself/.

e: all plants in coco are doing good? then it might be something in that soil mix affecting ph /nute uptake/

I am not running 12/12 from seed because someone said that it is better to let plants veg for while. I just cant remember who it was. I am verry bad with names.
I have also dreamed about this canopy of buds that are made of plants that each have 4 buds. I hope I achieve that so I can show you what I mean.
If you have time to tell me what to do when I am clearly doing something wrong pls tell me. I'd be grateful.
I did find my ph and ec meter and measured them from my tap water.
ppm was 80 and ph 6.5.
2 times a day sounds too lot of watering to me so I think I stick with my autowatering yogurt cups.
My yogurt challenge plants are doing fine except some nute deffiencies on bigger older plant. I will increase nutes from recomended if it does not fix its self before next watering.

 

[kasvi]

Here is my update one day late.
I did try to take pics of induvidual plants but they came out shit so I dont show them to you.


Case 1 plants

You can see one plant that looks withered. That is one that I accidentaly topped and did not remove top because I was hoping that it did not die. But it did. After taking pics I did cut that withered part of and bellow it there were 2 shoots already growing bigger.

Case 2 plants

I dont remember anymore if I gave full strenght nutes to all coco plants except smallest one last time I watered. I will use full ammount of nutes next time I water bigger coco plants and wait to so I can see if they are recovering. I surely hope so.

I started to mix leonardite to my coco nutes because I have been reading book "Humic, Fulvic and microbial balance: Organic soil conditioning" and Fulvic acid seems to be magic.
I will switch to Raw full up when I have money to do so which is in 2 days. I am going to buy timer to case 2 on same day.

I have some sad news also. I had to stop smoking weed because I have cognitive test because of my mental illness and smoking weed every day is not going to help on those tests.
Those test are going to be made after 6 months of abstinence.
I am easing symptoms of not smoking with microdosing psilocybin mushrooms and it is working great. I dont feel restless or urge to smoke weed. But dont get me wrong, I would still love to puff on fat blunt but there just is no need to do so.
My dose is .2g as needed which is about 2 times a day. I am not sure how long I need to microdose but I hope restlesness and urge to smoke is gone in 2 weeks.

 

[doams]

I dont want to bitch about that ph any more coz I might sound like a crazy mofo lunatic like those jehova witnesses or something
I am sure you will find out after some time /my first and 2nd grow was shit due to that/ im still learning and not there yet.
ppm 80 water is my wet dream my tap is @800 was using bottled water last run with success /kinda/.

6 months of abstinence something I would never ever do.
but I agree after two weeks of cutting thc from the system it will go back to normal at least for me first week is the worst then it will stabilize.
I just cant stop vaping even for one day that would make my life miserable AF.

Jesus.. I would rather get addicted to codeine.. y`know? Like a real addiction,.. getting addicted to weed is like stealing from the dollar store

Does the 3D printed filter work?

If it does, could you share the file? I am currently building PC growth case for Antec P182. I am still missing few parts like the filter. It seems to be really hard to source suitable building materials for it without access to proper tools.

Hey man, this may be an easier build for you unless you have access to the 3d printer easily? This guy says it works well and it loks pretty easy to builde. I am just waiting on some fans being delivered and I am going to give it a go myself

 

[repuk]

kasvi, do the leaves feel brittle? I'd say those seedlings look "cooked".

Sick project going on here, loved the 3D printer stuff you made my imagination go wild!

I will elaborate further, but if I were in your shoes, this is what I'd do:

Criteria number one will be making as much free space as possible.

- Use quantum boards/strips. I would test first using the whole PC cover as passive heatsink for them by thermally gluing them to it. If that doesn't cut it, then I'll look into an active cooling system.

These are to grow drosera dichrosepala (carnivorous plants) which I think have a similar light intensity needs as cannabis, note how height space is similar to a PC case:

Which ones fit your cases? LT-Q282A (27.5cm), LT-Q562A (56cm)?

- I would go single plant, straight to 12/12 from feminized seed, (or cuts if you can source them) then shape it Blynx way.

- Would use a coco square slab (to gain even more vertical space) + canna coco A+B and hand feed for starters, less variables to worry about than in soil.

- Would use a Raspberry integrated in the case to control everything (only one cable going to the PC case), plus Mycodo. I bet you're handy with electronics if you managed to build the 3D printer, this won't be any different to assemble. It will allow to automate lights on/off with timer or cycles, control intraction/extraction based on temps and/or RH, etc.

You can even control light intensity (using a dimmable driver) from it, so that it lowers it if heat becomes a concern, or to create different "light cycles" (seedling, vegging, flowering) with different intensities and hours cycle. The plus: constant monitoring and a sick dashboard to see what's going on even from your cell phone (can give you a hand on securing it network-wise).



Adding a 4 rows LCD display is easy and cheap (and will look sick on a PC case 3,5" bay, not losing stealth):



A suitable dimmable driver if you go this route can be the Mean Well IDLC-45-500. Will research more and get back.

Again thanks for tips. If you look closely, nasty leaves are at bottom. I think it was because there was fertilizer build up at trays and it made super saturated solution everytime I watered. I did not realised this when I used trays with organic soil and it killed many plants.
I did leave fertilizer water on purpose in trays so that I dont need to water too often. Small pots dry out too fast.

LT-Q282A fits my case perfectly. I have been thinking about making my case automatic with pi, but I have some other electronics projects going on so I cannot do it right now. I think I can make my pcs automatic after next round. Then my projects should be done.

I had success with organic soil in big tent and would like to try it indoors with one or two plants in as big underwatering pot as fits there. If that wont work then coco with coco nutrients and automatic watering.
I have grown chili peppers in organic soil in 1,5l container so I think I can do it in little bit bigger bottom watering container with cannabis.
I can fit total of 4 liters of soil in there in 2 bottom watering container like this.
https://www.orthexgroup.fi/tuotteet/kasvien-hoito/kestokasteluruukut/pauliina-sailioruukku-17-cm

I have mother plant that I can take cuttings from after some time.

Can that driver be used as normal driver if I dont connect it to any kind of controller? If I read datasheet right it needs singal to be at 100% light intensity. No singal no light.

Coco coir with Advanced Nutrients pH-perfect nutrients. Last run in my micro tent (30x30x50cm) with 4 x 20w E27 LED spots (Airam and Osram are available locally I yielded 50~ grams dry + some trim. It was with a random autoflowering NYCD seed, not sure which breeder. Definitely better to have a single plant in a micro grow than multiple tiny containers that yield less total than 1 larger plant.

The AN nutrients have made coco growing so simple, I don't measure anything and the plants are healthy through the whole grow. The Orthex pots are a waste of money IME, you have to flush the coco every now and then and the water area in the bottom is just going to store up all the salts.

 

[repuk]

I think given your restrictions in space, a single plant with a "decent" root space, and enough canopy space will yield much better than two or more space-hindered ones.

That's why I advise coco as medium; even using a slab (which fits nicely inside a PC case using mostly horizontal space), is nuting frequency what counts, not overall volume. Using a blumat will feed the girl as she demands, and usihg a slab will make the most efficient use of volume available inside the PC case thanks to its cubic shape.

You're basically going to run a SCROG-like grow (using Blynx technique), and this requires as much root real state as possible; SCROG plants are big plants crammed on small spaces, And pot size has a direct influence on yields.

You need as much vertical space as possible, as you need to leave proper canopy distance, and space for buds to develop. That's the reason for thinking on coco and quantum LEDs, having as much useable space for actual "green" as possible.

Small spaces are rather critical to keep on steady temps and RH. If you don't want to go with the raspberry, I'd either build a temp-controlled exhaust fan, or use an inkbird ITC-308S like device.

You can use a non-dimmable driver, of course. Given how cheap they are you can always purchase a dimmable one in the future if you decide to go with a Rapsberry... or purchase two different ones to use for vegging and flowering.

 

[repuk]

Now going to actual LED implementation, I'd use 7x LT-Q282A in series for a total maximum global power of around 35W, don't think a PC case can stand more than that, in fact is very possible that you actually get better results dimming it down to about 20-30W per sq feet, how many sq feet does your flowering PC case have?.

A MeanWell ELG-75C-500B looks like it will fit the bill, and it supports three dimming methods: voltage, PWM and potentiometer.

Each LT-Q282A has a forward voltage of about 11V; seven in series = 77V, ELG-75C-500B should fit the bill nicely; constant current region is 75-150VDC so it should drive seven LT-Q282A in series fine, allowing for 250mA-500mA dimmable range (max per LT-Q282A is 450mA, so dimming range would go from 55% to 100%).

You could use e.g. 4x 3000K + 3x 5000K. Each LT-Q282A will be providing about 1000 lumens, so max will be 7000 lumens, which I think is more than enough for the space.

You can dim it using a regular potentiometer, and you'll be able to dim it in the future using PWM or fixed voltage too.

In case you want to go simpler and cheaper, an APC-25-350 (non-dimmable) will fit the bill nicely with 5x or 6x LT-Q282 in series (e.g. 3x 3000K + 2x 5000K or 4x 3000K + 2x 5000K), running at 350mA (77% of max LT-Q282 power) and producing about 25W max.
