Plan: 2x 38 Gallon pots. Scrog in a 8x4 tent need advise,height......

Whats up my brothers,

Never scroged before but i am eyeing to scrog here soon, two giant plant bags,
24x24x16 inches each.

Question: My tent is a 8x4 and 7.2 feet high.

Grow time is no problem, but how high do i set my scrog screen since i have a pretty high tent to get the optimum out of the space and these pots?!

Would love to hear some opinions and suggestions

Much love

Are you using the screen to ultimately support the colas? Many people call that a scrog, I dont personally. I have the screen about 8-10" above the pots and keep tucking and weaving until the screen is about 70-80% full, then all the bud sites start growing up and the next trick is to try and get them roughly the same length, bit more tucking and about half the total length you want before flipping. I say 8-10" clearance from pots so you can get your hands in there for maintenance, watering and pulling off undergrowth.

If you are just separating branches and supporting your plants its probably a good idea to use two screens/nets, but you still need to get in underneath. Use the first net to shape and the second for support as the colas form and get tall and heavy. I think they call it a second trellis. Probably a thousand videos to be found on youtube.

You think 38 Gallon pots are too much?? how long would you veg them?
And what can i pull of them two plants scrogging compare to regular grow, just one time fimmed long veg to reach as much of the height possible my tent gives me. What would be the better way to go with those two giant pots?

How tall do you want your plants? if you are trying to grow trees then a screen probably isnt going to do you much good. your plants will about double in size from the time you flip, genetics play a factor. Grow tents are the height they are so that you can get in there and work comfortably, seriously go crawl around on youtube keywording scrog for a bit, or read some grow journals here where people are screening/scrogging. I use fabric pots, cant remember the gallons, but they are approx 15" in diameter.

I saw this guy once (online not in person) who vegged out his cannabis plants to about 6' tall and then asked why isn't it flowering? A lot of wasted time and water, dunno how that worked out, but I am guessing he would have had to cut it way down or the weight of the flowers would topple it.

38 gallons is pretty big. i grow in 5 gallon smart pots and some plants can fill a 3x3 canopy themselves.

pretty sure most people would use those bags u have for outdoor growing massive trees.

if you're gonna grow in 38 gallon pots i would start with a lot smaller pots and just keep vegging and training the plants to grow horizontal and transplanting up a few sizes at a time. i think indoor a pot that large might just be overkill no matter what though. i think you'll find a healthy plant in 10 gal pot and good lighting can fill a 4x4 canopy easily.

Hi! Are you limited in the number of plants you can grow? Why only 2 plants in a 4x8? I grow 4x10g in a 4x4! Most of people in EU grow 9(2g or 3g) in a 4x4(most only have 1 room so we need to have the shortest vegg possible)
10g or 35L is enough to get a big plant indoor...most of the growers use this size with very good results!
Using only 2 plants in 38g or 130L pots will lead you to a never ending SCROG and if you really want to go this way you will need a solid net or a piece of fence and do as Canadian 1969 said go under and above the screen to help the plants support all the weight of the future buds! And depend if it is an indica a sativa or an hybrid fill the fence 80%(I) 40%(S) 60%(H)for real sativa(between 16 and 24 weeks)10/20%!
And when you switch to 12/12 you just shave everything under the net! That's why I start SCROG from the fifth pair of leaves (1st is false leaves 2nd have only one "finger"(can't remember the English for this sorry)3rd only 3...the fourth pair is the first real pair of leaves so I get rid of the 3 first pair of leaves and then I start the SCROG! I try to let the light far away at the beginning to have enough space to water after and because we shave everything under the net anyway I try to stretch it at the beginning which is easy to do!
You can do it with 2 plants in 38g but you will loose so many time to vegg this two big mama! I would have go with 8 plants in 10g this way you can vegg 8/10 weeks to match bloom time and have a perpetual grow...i guess you have a vegg room!
With a SCROG you will need to vegg and bloom in the same room unless you use wheel to move the SCROG I already saw that...because the plant is inside out the fence you need to move the all thing from vegg room to bloom room so the guy used wheel on a piece of wood to transport!
If you go for a SCROG in 38g could you share a few pics please...it would be an epic SCROG! And don't forget to think flat and to fill the screen with plants till you can't see the floor anywhere and remember that when it will be cover by plants you will need lot less water!
Have a lifted one and lots of good vibes from France

Much love from across the border my dear brother!
Im in Germany my man!

So brother, if i decide to grow just topping the plants once and then just let em grow tall and strong.
Spacewise, would you still suggest 8x 10 gallon pots?!

Cheers

Hi! Lucky German guy!!! One of my best friend have the same name!!! He is from Algeria(Setif)!!!
You guys have a medical program...i guess we are one of the last EU country without one...the last country of western Europe at least! Maybe it is because our health ministry use to work 14 years for bigpharma or because same bigpharma paid our prez campaign...President who write a book before election and where he said he will legalise if he was elected...and now French baby will have to recieve 11(eleven) vaccines instead of 3!??...coincidence??? Sorry for this!
Yes I will definitely go with 8 or even 10X 10g!!! Even 12 if you plan on going lazy...more plants more used space more surface more buds in less weeks! If you want to SCROG then go with 8!
With only 2 plants you will vegg for 3 month or more and will have to do a lots of training and topping! With 8/10 you will need 2 monitor 10 weeks with topping if you SCROG you will need less than 2 month because you don't top you just train and lst!
Fastest and without work is 10 plants and topping or 9 for convenience 3/3/3! To make thing easier use solid nutes you mix into your soil or in top layer to be able to watering only with water all along(you can use a bit of molasses and milk during bloom to boost the nutes!)

Much loe from over here and many thanks,

So how long would you veg the 10x 10gallon pots space wise.....only two to four weeks veg???!
Just thinking beacuse 10x 10 Gallon pots seems like too much in a 240x120cm tent.

Hi! 10 gallon is 35L I have 6 in my 4x4 and 4 in my 100x100cm(40"x40")! Most of the French growers don't have a lot of space so we need to be as effective as possible to grow the biggest amount of quality weed in the shortest amount of time!
I bet we have the best scrogger in the world here!
When I started growing in 2001 I had T5 neon light and because there is not a lot of penetration I had to go with small plants in my 40"x40" so I went with 32 x 1g pots(3.5L)...a few year later I start using a 250w and a 400w HPS and then I started to grow taller plants but less plants(16 x 2g pots)and then I bought a MH for vegg and a 600w and then I used only 9 plants in 3g then I switched to COB in 2015 and at the same time I went full organic with solid amendments you mix into the soil and then only use water all along(I use molasses and milk during bloom) I was going 9 plants but while my 9 plants where waiting for me in the garden I was washing my box for the new bloom some f.....g cats eaten 3 plants so i had to use all the space and went to buy 10g pot and i saw that 6 was very good and filled my solid net very fast!
What I want is to have plants everywhere and since I shave everything under the net I have all the space I need to water! If I can have 6x10g in my 4x4 you can go with 10 in twice this space! I would love to be closer and be able to help you more!
The less plants you will use the more vegg topping and training you will need...you can save weeks using more plants! And I guess you can make clones so it won't be a problem! And this way you can try more strains and genotype to find the best one for you!
What's your favourite strains and breeders???

So for how long do you veg in your 10 gallon pots bro?
And any pot brand that you use in particular i am thinking of using these kind of 50l pots maybe since i got a high ceiling to go with:
https://www.ebay.de/itm/50-Liter-35-x-50cm-Pflanzsack-mit-Henkeln-Grow-Bag-Pots/162080782812

I am looking to grow some strong medicine brother, a 1:20 seed from Medical Marijuana Genetics called CD1 Candida.

And then Super Silver Haze, a 1:1 seed from our boys from Greenhouse Seeds from Holland.

Here are the links:

https://shop.greenhouseseeds.nl/super-silver-haze-cbd-feminised.html

https://mmgenetics.eu/en/product/candida-cd-1/

Hi! Usually I put my seed in a cup for a week then 2 weeks in 2g and depend if it is mostly indica I go for 3 weeks vegg in 10g and for hybrids only 2 weeks!(with very long sativa I do 1 week or no vegg depend if it is 16 or 22 weeks but I do not grow pure sativa often)
About the pot I use to have regular plastic pots but I switched to fabric pots like Root pouch...plants grow much better in tissue than in plastic! The roots act in a different way in fabric pots and increase the grow rates! There is square 10g fabric pot I guess it is what you need...i have the round one but I would have buy the square one if they were available when I did!!
I don't remember the English word but you know the plastic thing you put under your pot to keep water from flooding everywhere...i use a 4x4 one and with fabric pots when plants are in the 10g pot when you water even if a lot of it go thru the pot it will be sucked by the bottom of the pots anyway so no watering problem this way!
A lot of people use only coco mix with perlite or vermiculite and canna coco nutrients with awesome results! I prefer an all organic nutes but if it is quantity you looking for go coco!!!
I never heard of cd1 Candida but it sound a lot like industrial hemp...go check the official industrial hemp seeds allowed by European community!
For high cbd seeds I would have choosen any Swiss breeder because it is their speciality since they can have 1% THC allowed and as many cbd as possible! They play with industrial hemp and classic strains to get the best of 2 world's...lot of cbd low THC but tasty!
About greenhouse...i used to really like Franco(RIP) but it is more a seedbank than a breeder especially since Franco passed away...i don't say they have only crappy seeds and for the price it is correct but if you plan on doing clone I would go with sense seed SSH or even the one from home grown fantaiseed!
If I learn something along these years is that seeds have different level of quality...and price isn't always relevant! Take KC brain for example it is less expensive than let's say 00seed bank but I would grow any KC seeds but I will never buy anything from 00seed the first is a breeder the second a seller who probably have the same genetics than rqs greenhouse and all the cheap seeds seller!
Is it your first grow?
Do you know SSH will take about 12 weeks to be really mature...if it is a real SSH! I love haze too but most need more than 10 week to be ready as there is haze in the strain(Jack Herer sativa phenotype takes 14/16 weeks So when I see 9 weeks on greenhouse site it can't be the real one or they lie about the flowering time!) And Candida will be ready in 9 week I guess! So it won't be ready at the same time! That's why your light should be in 3 or 4 part...4 panels to be able to switch some off when you don't need it!
I bet there is a thread only about SSH here on RIU so if it is your favourite smoke I would try to find the real deal the one who taste like it should and who grow big and fast frosty buds!
About the high CBD strain low THC the most famous stable and tasty are : Charlotte's web/ Ringo's gift/ AC/DC/ Harlequin and Mom's boy(seed2soul) those are some of the most famous high cbd strains in US!(Charlotte's web should be 0.3% THC and 20% CBD with a large spectrum of cannabinoides!)! When I talk about stability I mean you will get almost the same ratio thc:cbd on every plants...because sometimes it is not the case and you can have huge difference on some other strains even have more THC than CBD!
I forgot the dinamed from DINAFEM this one is a true med plant too...no high the on this one but high cbd and taste(I tried once a few month ago and for a cbd plant I was very surprised by the flavour!
About soil and nutes what are you going to use? Have you ever tried guanodiffusion? It is very simple to use and provides wonderful frosty tasty nuggs! It is not expensive and keep you away from overfeeding and burn! Medium is important too what are you going to use soil/ coco/ flakes/ hydro/ a mix?
If it is your first grow you should keep it simple...don't go for a nutrient line with 20 bottles and super expensive seeds! Most of the time I allow me a budget of 60€ per plant (8/15€ seed 10/12€ soil and about 25/30€ nutes!)
Nutrient and medium play an important role in the finished product quality and quantity so I really encourage you to grow with organic amendments in an organic soil and to use automatic watering(I can't remember the name...i have some...lol!...it is ceramic plug you put into the soil and when it is dry it water your plant without pump you just need a tank with water 30cm higher than the pot...organic needs to be always moist to be the most effective same for temperature under 18°C it do not work well but since we need to be between 22 and 26°C to please our girls it won't be a problem!
If you go this way solid amendments and top dressing plus the auto watering you will only need to fill the tank do a little training to fill the space and to hand water once a week if needed!
Don't forget to use any organic pesticide for prevention!!! It is very important to do it very!!! And to use traps(yellow and blue little trap who appeal the bugs and glue them)! You don't know how it is important to prevent until you have a bugs invasion and have to throw all your plants to trash and cry! So prevention is the master word to don't have to spend hours trying to kill microscopic enemies and turn mad or have to use chemicals(and we smoke that after...i started growing to have clean medicine so never use chemicals! I did but I didn't knew what I know now!!!)
Have a lifted one and lots of good vibes from France

I have 8 plants in my 4x8 with about 1x4 of the tent for dehuey etc. Unless ya restricted id probably do at least 4 for a scrog or youll be vegging for a year

I don't think a pot that size is necessary.
I've done a 2lbs (dry) plants with 7 weeks veg in a 12 gallon air pot.

So you would recommend vegging longer (6-8weeks) in 12 gallon pots......?!

Just out of curiosity, How big (what are the dimensions) of the 12 gallon air pots? Ive never used them , currently I use fabric.

just checked mine are
30 x 37cm/11.81 x 15.57" (HxDiameter), so about 8.5 gallons ish

I use 3x3 4 gallon fabrics (3R)
in 4x4 space, main-lining, solid amendment, blumat, about 3 potting before flowering.
growth time depending sativa/indica/pheno , and the apex numbers wish.
working in space is easier with 8 plants.

I don’t think you need 4 gallons if you dont use organics solid amendment.

Sorry forget what I said about SSH! I didn't get it was the cbd version!
If you want to go with real cbd strains you should try Swiss breeders seed or the high CBD US strains I mentioned!
It is a huge industry in Switzerland because they are allowed to grow 1% THC strains!
I think they try to develop high cannabinoid content strain and same with terpine!
There is a huge difference in aroma between a 0.3%THC weed and a 1%THC one! I tried both and no comparison! Even the effect is not the same even if it very light...the first you fell nothing special and it is not very pleasant to smoke the other is very cool to smoke and you fell relax! Not stone at all just cool like after a good massage!
May I ask you for what condition you will use it? Are you sick? I have family member who have died from brain cancer last year and when I told my family cannabis can cure this kind of cancer they watch me like an alien...a few month ago it was on us cancer research site and a professor in Madrid had great success on rats but he stopped his research after this success why...bigpharma give money to the university So...!
Who will be the first country to legalise in EU to you? I want to say Greece as they are economically in deep shit and they started their medical program more than a year ago!!! Or maybe UK as they already have a big growing facility(GW pharma)
Have a nice one

@salah. You can veg quite long in 12g. Once I got a cutting from someone really early and ended up vegging that one cutting for 10 weeks. It was a regular 12g ( non fabric or airpot) and it ended up with 3lbs. Mind you this was about 7ft tall indoors with vertically mounted 600w hps (in cool tubes) in front and on either side of the plant.

At the moment, because of LED I'm doing purely canopy scrog. I recommend having more small pots than larger because it'll save you more time filling the canopy out. It'll take 6+ weeks to fill out a 4x4 area "densely" with 12g pots

The place I bought them at advertised as 45 litres. I guess they are only slightly larger than yours dimension wise. These are 6 weeks into veg. I got 5 gallon fabric pots too for comparison. In my current opinion @6 wk veg, the 5 gallon pots are roughly 60-70% the size of the 12g. I'm pretty happy with that.
But I am feeding the 5gallons 5 times a day and the 12g 3 times a day. The 12g pots sucks up over 1.2gallons of water a day without runoff!
I do things a bit differently than everyone else, my coco is usually always saturated.

BLUMAT that's the name I forgotten!!! Those are so usefull with solid organic amendments!!! A life changer!!! Just a few hand watering with molasses and/or fresh milk(20%)! Try milk at 20% week 6 and 7 just when the buds start to get weigh and fill the sites!!!
There is different size in 10g there is normal round 10g there is flat round 10g and my favorite are the square 10g! Our tents are square for the most part or rectangular so i prefer square pots...because if I have to do a fast crop I just fill the tent with pots till I can't see the floor...why I wouldn't use all the surface exposed to the light...and I have multiple light source due to the spacing of my COB they can light 30x30cm 1ftx1ft so I have 1 COB at the center of each ft2 of my tent so the same light intensity everywhere in my 4x4(16 COB @5 to 50w but I use it at 35/40w during bloom)
I can put 9 x 10g in my 4x4 and it is full square fabric pots are 16x16x13"(40x40x32) so yes you can put 18 in your box! But as they said it is nice if you use organic solid amendments and reuse the soil several time!
If you want to go faster go with 25cl cup 5/7 days then 1g(3.5L) for 7/10 days then 5g(18L) 10/14 days then bloom for the amount of time your strains need! And 18 pots nine in each 4x4 (you can put 32 if you want!)
If it is for your personal use only you could use a part of the tent to vegg and the other part you can have a perpetual bloom! Use clone and vegg it 4 weeks replace half of the crops do it again and replace the other half and on and on and on! This way you can harvest every month!
Tall plants are for outdoor or 1000w de(who have for the best about 4" or 120cm penetration) when you grow indoor under led you have to think "flat" the more space you cover with plants the best it is for yield!!
I let you meditate on this
