Indoor sativa grow question

I'm setting up for my next run which consists of

2x Ace Panama x Banji Haze fem
2x Ace Zamaldelica fem
2x CBG Destroyer fem
2x Beanhoarder Sour D x SSH
2x Peak Sweet C99
1x Ethos Black Fire Chem

My question pertains to the first 3 strains, this is my first attempt with sativas. I'm trying to decide between 2 gal and 3 gal pots. This will be a soil grow, light super soil to be exact so I have the option to add nutrients if requires. The other plants will get a mix of light and heavily amended super soil.

I understand the rootbound technique of forcing flower but I also dont want to short myself too much on final results by going too small. I plan on topping at least once and will do lst as required.

I can handle a final height of between 48-60"...54" being ideal.

Plenty of light, 600w hps, 450w (actual draw) g8 led and 4 autocobs.

So...2 gal or 3 gal pots for the sativas?

Any other tips are welcomed.

In a High Times issue on growing sativas the author used very large pots. I think it was 10gal. in veg. and 20 in flower. Of course you need large spaces for that but you get the point. The bigger the better.

Hey Fitzera Nice seed selection. I have best control starting with small pots as possible at first till roots show out the bottom then step up to the next size till you get to the end of your veg stage weather starting from seeds or clones. The last transplant should be shorter time duration and the rootball less developed and always go into as big as you can pot size in the end.

I'm growing some Nigerian, I start with rooted cuts into 3" for a few days under vegging hours, I use 12-5-2-5.
Then I transplant into 5" for two weeks and develop the plant shape as it vegges.
Then I plant into 1.5gallon and start 12-13 for another 2 weeks.
Next into 3gal one more week at 12/12 where then the plant starts to convert energy to flowering and stretches rather than getting too much bulkier in size.
Lastly into 10gallon till finish where they have enough nutrient amended already composted coco soil to properly finish in two or three months. If I need I have already composted bloom amended coco soil to top dress with till finish.
In small pots you will get root bound quickly especially if you amend the soil and use nutes, I think you gotta watch out to not rush the plants at first and get a big plant and then put it into flower when it's using lots of water and root bound.
This system need to be tailored to variety being grown and takes a little thinking with each variety each time getting better on the timing due to growth rate and stretch rate for that variety.
Hope that helps and gives you some food for thought. Good luck, can't wait to see how it turns out for you.

I read somewhere - maybe on here, maybe on another forum I lurk on - that smaller pots are key to running landrace or hyper stretchy sativas indoors.

The basic technique is to veg for a few weeks from seed in a small pot then chuck them straight into flower. You allow the plant to get root bound until it's done stretching then pot up once the final height is reached allowing them to use the new soil as food for the buds.

I've not tried this yet myself but the next grow I'm doing will be ace Panama for f2 seeds and a cross with my main two mums and I'll be trying this tech on the Panama to control height and run the cycle faster.

This is exactly where I'm coming from. The thing is, I've been seeing some grows where they were in bigger pots, topped multiple times and that kept the final height below 5' and lots of flowers. So I'm just trying to make the decision as to 2gal or 3gal for my first attempt. I'm leaning towards 3s

Root binding technique? Hippy bullshit. Show some science.

But this is the internet, so transplanting stress is a myth. In the real world though, transplanting is for suckers.

A 2 gallon pot will probably produce a tree unless you flower very early and can train the plant. I use
no more than 14 hours to vegetate Sativas and flower after 2 or 3 weeks. Sativas will stretch a lot
until flowering is well on it's way which is normally at least 5 weeks into flowering. Go light on the
nutrients. Too many people fry their Sativas these days with every nutrient under the sky.

Thanks troutman! Exactly what I wanted to hear. I've got the seedlings under 18/6 currently but I'll switch that up to 14/10 shortly. I saw a post where you mentioned they dont require more than 14hrs of light in veg and anymore is a waste of $.

My plan was to switch to flower at absolutely no taller than 12". Topped at least once, if not twice. But I also have a 2 week vacation coming up so I have to play it by ear. Take it as it comes.

I use super soils, one is store bought and I find it's not hot. Never burned new seedlings. Also never provided enough nutrients to take them to harvest. I also build my own recycled soil that is heavily amended and had nitrogen toxicity on the last round but did provide nutrients right to harvest. I was thinking I might throw in 1/4 of the hot stuff mixed into the mild but I dont want to fry them. So I probably best just use the mild and use fertilizer when required.

I normally use Pro-Mix with a little extra added vermiculite and try to feed mostly organic
if I can. I also don't feed until they make their 2nd or 3rd set of real leaves either.
