First extreme sativa run - please advise

[Cheyos720]

Hey folks,

my first sativa run is currently underway with three genetics from ACE Seeds. These are the following strains:
- Purple Haze x Malawi
- Zamaldelica
- Golden Tiger (3rd Thai-Dominant Version)

I am currently growing three plants of each strain in 1-liter airpots. In the long term, I would like to keep three plants to cultivate them in my tent (1.2 m x 1.2 m x 2.2 m) under a 500 watt lamp. The plan is to repot them in 15-liter fabric pots soon.

However, I'm not sure how long I should keep the plants in the vegetation phase (18/6). The Golden Tiger in particular is growing much faster than the other varieties, which is starting to worry me.

My plan is to top all the plants from the third node onwards, shortly before flowering a second time and - depending on development - possibly a third time (probably at the start of flowering). After that, the few main shoots will be woven into a SCROG net.

Here are a few photos:

I hope the growth rate is recognizable in the pictures.

I have two final questions:
What do you think of my plan?
When should I send them into flower?

Kind regards

I won't plant them in direct in 15l pots if size is your concern. Better repot more often like in 7l a few days before flip and in 15l when the stretch is over.
i have only experience with the gt 3.0 but 2-3 veg are enough imo.

Thanks for sharing your garden with us friend. You have a super line-up of strains. I wouldn't worry too much now because you have a way to go. When the time comes you can pick out the finest females and see how they respond to your growing environment. Those Sativa seedlings need special attention and you are doing well with them. It will be interesting to watch so keep us posted friend.

In a small space such as yours I would keep them in the small pots and switch to flowering light cycle now. Once flower is set you can transplant to the 15L pots for the remainder of flowering. This should keep the plants somewhat manageable. You will be tucking and pruning I'm sure.

Thank you very much for your numerous answers.
I am considering repotting the plant twice, but I would put the plant in a SCROG net so that it is not mobile and cannot really be repotted by me.

I'll get back to you as soon as the little ones have grown a bit bigger and the situation becomes more serious or it becomes clearer when they will be sent into flower.

I am confident. They are currently getting 100 watts at a distance of 35 cm. They are no longer sparring and seem to be tolerating it well so far.

Keeping such Sativas under 18/6 will ensure extremely great yeilds but no space for them as they get into flowering, also 12/12 and then going down an hour every several weeks would be recommended if the space is truly that tiny, the potency and quality would be the same, the yeild would be less though

One suggestion for a 2x2 tent is to keep them all in that same pot you have until they sex. Have a plan to control height (scrog, or prunning, bending) 99% chance you will run out of space (vertical and horizontal).

I would have started at 12/12 heavy sativas will veg under 12/12 until 10th-12th node of growth and then they are sexually mature (in most cases). They grow vertical while they veg and then they stretch for a good 4 weeks while the hormones set in place. Then they keep stretching if the photo period remains at 12/12 even 11/13. Most sativa growers will say 10/14 9/15 is the final photoperiod for heavy sativas.

Thats a Purple haze X malawi... HUGE when they veg.

Congrats, it's a boy!

That’s 2 years ago, wasn’t really looking for a male Malawi dom. If Haze dom different story.

Just an example of what does veg plus big pots to a sativa dom cultivar.

Good luck on your grow

I've grown the Golden Tiger, Malawi, and Oldtimers Haze which is the mother to that Purple Haze and one of either plant will easily fill that tent if you let it. Best to flip sooner rather than later if that's all the space you have to work with.

Good luck.
