Epic 50 Seed Super Sour Diesel Pheno Hunt in my 2x4! Help Growmies!

Hello everyone!
First time grower here but very passionate and ambitious, Please Watch the full Video Linked below and let me know all your thoughts on my setup, I could use some help on the feeding schedule and would love to know if there are some sativa experts that could guide me through this phenohunt of this Super Silver Sour Diesel Haze. As you will see in the video I am a very confident first time grower and could use some feedbacks!


This is the plan:
Today I soaked 55 super sour diesel seeds from reservoir seeds in some 0.75% hydrogen peroxide and spring water solution at 5.85ph. Tomorrow I will soak some organiplugs in a 0.5% hydrogen peroxide solution and have them sprout in the humidity dome. for the first week till they are in the rooters i will feed only 20ml/gal clonex for seedling and then start with the veg feeding schedules attached. After the plants have reached a few inches and have a clonable top I will top all 50 of them and after about a week till they root nicely in the organiplugs i will then transplant them in some small pots that i measured, 50 of them will fit perfectly in my other 2.3x2.3 spider farmer tent. and after 2-3 days still at 18/6 i will then flip to flower to sex the main ones in the 2.3x4.6. hopefully I get at least half females and from those i will select the best 18 and transplant them into 1 gal pots arranged in 3 rows of 6 to achieve a Sea of green, if you have any advice on how to find the best genetics already from the vegetative stage let me know, anyway i will select the 18 i like, take some cuttings and flip them to flower, scientifically 16 is a very fair number to find a pretty good pheno at least for a homegrow situation. then I will select the pheno i like the most and just keep running 2-3 plants per run of that one. I know its gonna be pretty crammed in there but i found it necessary to find a good pheno.
Now that you know what i am looking forward to please watch the video in full lenght and let me know all your opinions on any detail you might find i am forgetting, i have been very synthetic and it should be an enjoyable watch. I am really curious about the feeding charts and air circulation techniques you guys run.

Don t freak out on the number of plants because i ve seen it happen, although the plants will grew less colas its still possible to get good results to find the best genetic expression. I have seen guys on youtube grow 9 plants in a 2x2 or 50 plants in a 4x8 and one dude even grew 16 in a 2.3x2.3 so i am sure with care and attention to detail i can achieve it. Check out yt channel called 2x2 growing

Please also watch this fenomenal video produced by cannacribs at the Amaze cannabis facility. It's super entertaining to watch and It will give you the whole idea on how I am trying to approach this grow. Much respect for them


The medium i plan to run its gonna be about 75% coco-perlite (70-30) from Motherearth 17.5% brut worm castings 5% biochar (pistachio shells) and 2.5% azomite micronized, i plan to feed at 5.9-5.95ph since i have a small amount of worm castings and will have lots of microbes in the medium.

The feeding charts shows a pretty heavy amount of different nutrients i will update soon on ec and ppm levels. for the first 2 weeks of veg i think i should feed about 1.2 to 1.5ec at most and then reach 1.8 till flower flip when i will start feeding at around 2.4 ec. Something that scares me is that I have a lot of nutes like Recharge for example that you are supposed to add at the end of ph and ec feed solution measuring because they dont affect it but now i am wondering if all those compatible nutes will then raise the soil ec and when i go check the runoff i might find out its very high but its high of things that doesn t matter if they raise the ec and i will not be able to find out if i am having deficiencies or toxicities! (hope i am making sense here).

I would have a thousand questions right now but I ll have the thread unfold itself and I hope we all have fun discussing this crazy first time grower pheno hunt attempt. Ahahha sorry in advance to all the pros that have their hands on their head after reading this plan, i certainly know that i am making a step longer than my leg but thats me guys hope you understand that i am just very passionate and strive for excellence

Thanks so much for everyone taking the time to share their passion with me!

This will be the official grow journal and I will post any updates under this thread, stay tuned for a grow worth checking in to!

If you would like more info about the companies recommended dosages i will picture the label and post it

That's quite the nute cocktail.

Personally if I wanted to hunt through 55 plants I'd seriously start thinking about simplifying things.

You don't need a humidity dome for seedlings. You're just inviting dampening-off. Humidity domes are for clones, period.

Replace the coco with pro-mix hp, and then you won't need to ph anything. Many growers run into issues using a high % of coco in a soil mix.

Pick one bottle of veg nutes, and one bottle of flower nutes. Cannabis plants need N, P, K and sometimes Cal-Mag. They don't need a cruise-style buffet. Seedlings don't need much of anything. Some EWC in the mix will be enough for their first few weeks.

Sexing can take some time. 3 weeks from seedling on the quick side, to 2 months on the slower side. 55x 2 month old plants will be quite the jungle.

So keep it simple, and Good luck!

I wish you all the success in the world, but as many others have said this plan really needs to be reevaluated.

You will need a minimum of one month veg to get the plants mature enough to show sex/take clones. So if at the one month period you take clones to sex, you will need to take multiple clones from each plant to ensure you are successful with every plant, 110 clones minimum. You are looking at a week, possibly two weeks or even three to root/see sex.

If you get to this point, you now have your females identified but need to cut it down to 18 . Picking winning females in veg is a MUCH taller order than you are taking into consideration. 98% of growers, will have no idea what they have until they are done flowering. So while you can pick based on a certain structure, you will have very little to base your choice on that pertains to the end result. Stem rubs are something you can look at, but are really not as helpful as you might think, in my experience of course. This is why, typically, a pheno hunt consists of retaining clones the entire time the plants are flowering, you pick the best ones when you know they are the best ones. Sure you can weed out runts etc, However choosing after seeing veg only is really just flipping a coin.

Once all those bridges are crossed, you will have 18 sativa plants that you can expect to double or triple in size once flowered and they are going to run 80+ days. One of the biggest issues you will encounter is keeping 18 long flowering plants happy with the nutrient cocktail pictured above, this is going to be exacerbated by the small pots required to fit 18 in a 2x4. Small pots have no room for error. Watering and fertilization has to be on point at all times.

There are going to be a number of hurdles to clear to pull this plan off. I truly do not intend for this to come of harshly, I just want you to be fully aware of what you are attempting and maybe reevaluate after taking into consideration the advice that has been presented in both of your threads. There are decades of experience behind the folks who are offering up responses and it would be a shame if all that good will doesn't help you have a fun and successful first run.

I'll echo you cannot hunt effectively on veg characteristics. If that's how it was normally done, people would've thrown og right in the trash bin because they are some of the worst veg plants you can imagine.

Switch out all that extra for liquid seaweed/kelp which has all the aminos and enzymes. Recharge has humic and the sweetener that's all you need

Awesome reply thanks so much, agree on all your points, fact is i am very confident but i live in reality too therefore i decided to pop the 55 seeds to leave me some room for error, In my mind this is how it ll go, from the 55 seeds i soaked yesterday i hope 45-50 will germinate, after the first transplant i might lose 3-5, during all veg i might loose 5 for mistakes like under/over watering, bugs, nutrients toxicity/deficency etc, so I might end up with 35-40 plants at end of veg which at that point the clones i took from the toppings will have show sex and hopefully i have at least 20-25 females, I will then have to select the 18 i like probably base on node structure and height to get an even canopy and yes the super pheno i might looking for could be in the 2-7 i might throw out but what are you gonna do this is life.
regarding the clones yes it should be wise to get 2-3 clones per plant for insurance but i only have space for 50 pots in my other 2.3x2.3, so I will get clones from the toppings and if 6-7 die I ll just take cuttings about 5-6 days later from the main ones so hopefully i might just have to manage veg for 1 extra week but i can be sure i sexed right. what do you think about it?
Really appreciate you answer thanks!

Ok guys first official update

after 24h floating in 0.75% hydrogen peroxide water i took the seeds which were mostly still fully closed aside for 5 or 6 and put them about 1cm in the organiplugs, i took a bit of the side material and closed the center hole, i sprayed everything with the soak water. Before putting the seeds i soaked the organiplugs in some 5.8ph 0.35% hydrogen peroxide solution spring water and some clonex seedling feed at a small rate of 3ml/gallon. Put the cuties in a humidity dome and I believe the will need at least 24-36h more of total darkness before i turn on the lights, what should the humidity be inside there for this first stage? right now i m keeping it at 85%. For the first day i think i will do 70 ppfd and add 15ppfd a day for the next 2 days, then i will reevaluate how much light they need, anyone has any advice on seedling ppfd? i heard that for the first week or so it should not exceed 200ppfd or i could hurt them. Thanks and let's gooooo!

PS: after doing some research on how to best use the rooting plugs I soaked them at 50% water capacity. one plug dry was 6 grams and fully saturated 28 grams so i squeezed time till they were about 16-23g (of course i didn t weight every single one lol). any advice on this topic?

You are right and I am so sad about it lol but yeah i will have to select based on other traits like internodal spacing, leave size and overall health and hopefully the right pheno is still in that selection!

Please keep this thread updated I'm very curious to see how this turns out for you!!!
Good luck!!!

With much pleasure!

I also have an update on the medium, after watching bruce bugbee lesson on medium i think this is now how i should proceed, I will mix a 50l or 1.8 cubic feet or 26 pounds bag of coco perlite 70-30 with 12 quarts or 3 pounds of 3mm vermiculite (now that I am using vermiculite i will use maybe 30% less silica in the feed), 12 pounds or 10 quarts of brut worm castings, 2 pounds or 2 quarts of pistachio biochar, 50 grams of lime and 200 grams of azomite micronized. So to make it simple the volumetric percentages will be around what follows:

• Coco Perlite 70-30: 58.%
• Vermiculite: 18%
• Worm Castings: 18%
• Pistachio Biochar: 3.50%
• about 1% lime
• about 2% azomite micronized

and if you d like to know in lbs here it is:

the approximate pounds percentages for each component would be:

• Coco Perlite: 78%
• Vermiculite: 8%
• Worm Castings: 7%
• Pistachio Biochar: 5%
• less than 1% lime
• about 1-2% azomite micronized

Lmk guys!

I asked chagpt and she approved the medium bu i then ask her to make this medium even more optimal and it gave me these percentages:
Here's a revised mix based on the suggested adjustments:

• Coco Perlite: 80-85%
• Vermiculite: 5-7%
• Worm Castings: 10-12%
• Pistachio Biochar: 5-6%

What do you guys think?

I think percentages are going to be +/- 10% when you're mixing these things by hand anyway. Make a few cubic feet of soil and tell me how exact you think your measurements are afterwards

This are the parameters for now, the dome has only 1 tier but its very open and a bit of the 4 inch fan is flowing inside as well.
The dome is on the vivosun heatmatt set at 87f

Also contrary to what i say in the video i will run the spider farmer far red only after the final stages of stretching maybe around week 4 of flower

Ok little update on the the feeding charts, i reduced a few % of the raw nutes after watching the schedules used by Perfect gardens channel on yt

Seedling have been all night in darkness at 82%rh and temperature from 72 to 79, later on after the 48h of darkness period end I will turn the lights on at 70ppfd scheduled at 24h for the first 2 days then will reduce to 17.30/6.30.

after some research on sativa strains experts are saying that they grow naturally in zone with less light hours so they recommend 11/13 for flowering, i will do a mixed opinions process and have them 17.30/6.30 in veg and 11.15/12.45 in flower. What do you guys think about this?

Here s the revised nutes:

Yeah 11/13 works just fine, and is typically the advice for long flowering sativas. SSSDH isn't really considered a long-flowering sativa, so it won't matter if you run 12/12 or 11/13.

Long flowering sativas are more like 14+ week strains (or 20+ week strains) that will kinda keep vegging and flowering and never seem to finish. That's when you see the advice about 11/13.

Thanks that is so informative appreciate it a lot! this strain should take 10 weeks do you think 11.15/12.45 is best or should go 11.30/12.30?

Quick video update, lmk about the cO2 bucket if you have any experience and if that mosquito zapper may cause problems even with the black foam cover over the vents!

I was Thinking that I might skip on the co2 in the main tent till the 3rd week of flowering to reduce stretching, If I skip till that time, when I take cuttings from toppings or branches the moment they are ready to clone for sexing, I will the start blasting up to 1000ppm the 2x2 clone tent so they will grow faster and show sex earlier, so then I can manage better the main tent and veg for what's actually needed. just food for thought for now.

If I may make a suggestion...why not just forget about the c02 altogether and focus on other aspects first
