Jack Herer, Euforia - 11 days 12/12 - should i supercrop/pinch to control stretch?

[Max Headroom]

newb question: i have 4 euforia and 5 jack herer clones running in 11 l pots in my homebox (400 W). right now it's been 11 days since i flipped to 12/12 and they have gained considerable height and are ~50 cm right now.

i've never super-cropped before but it seems to be a good method to control stretch. i've read that you can even do this at the beginning of flower.

i have no experience running JH and i've grown euforia once from seed (them suckers grew TALL!)

i don't know which JH pheno i have, but i doubt it's the indica one.

should i pinch them?

 

[HighDesertJoe]

I don't like to pinch when I can SuperCrop the crap out of my plants,
here's one I've been SC:

 

[Max Headroom]

i was under the impression that pinching and supercropping is the same?

 

[guestaweed]

can one pinch / supercrop when in flower?

 

[Max Headroom]

i read somewhere that it isn't really a problem during the first couple of weeks.

wanted to get this confirmed by all the knowledgables here. i guess they aren't up yet.

 

[Greenwich Pope]

if i have one trying to 'take the lead' with nice off shoots i will pinch/bend the leader
not sure about the supercroppin in flower

what is your intention/save on height?

 

[Max Headroom]

what is your intention/save on height?

well, the box is 2 m tall (minus lamp, pots) - i've had some plants grow to the max height before and i want to avoid that this time.

if they double from their current size, fine. but anything more than that...
since i don't know how tall the herers are going to get, i thought of pinching them.
(i still don't know if pinching and SC is the same... anyone?)

 

[PistilPete]

Yes you can supercrop in flower. SC is just bending and snapping a branch/top to one side to shorten the plant.
By "pinching", do you mean cutting off tops to make multiple tops (AKA topping)?

No, they're not the same...have you ever considered LST'ing?

It's the bees knees for controlling height.

Supercropped in flower..... i snapped about 20" down the main stem and folded her over....

by pinching AND supercropping i mean rolling the stem between your fingers to crush the walls but not removing anything.
stem heals... upward growth temp. halted... plant bushes out... or something like that...

Hey Max

Hey Max

plants good great ...i dont think u should touch them anymore ...big thing is what your chems are ..cause they taste is the most improtent thing ... take out all the weights chems (big bud , overdrive , etc ) anything that say that it will make plant bud bigger ... that ish is full of nitrogen ..and that is really hard to get out of thet plant..ive grown jack alot ..and if u do just a an b . and one add one you should be good. and flush for 2-4 weeks ...then u should have some really nice meds !!!!!

 

[muddywaters]

actually, bigbud's mostly full of potassium, magnesium, and overdrive's 1-3-4 mostly phosphorus potassium and magnesium.

keep up the good work, your plants look really nice and there going to turn into some big monsters.

just recently herd about JACK. indeed nice keep it up well growing big buds anyway

ok, to clarify things, here is the definition from the sticky

Super Cropping

There is also a technique called super cropping, which involves crushing of the soft inner tissue of the stem. This technique will allow you to gain some control over the plant, but it is mainly used to increase health, potency and yields. This soft inner tissue is made up of cellulose and forms a network of vascular tissue that can be divided into two groups; namely the xylem and phloem. These two are responsible for the transport of water and nutrients along the stem.

Breaking the plant's inner walls will cause it to rebuild. The plant will rebuild the tissue stronger than before and this is why this technique can increase the harvest. While rebuilding the tissue the plant expands on the network of cellulose, which is why the stem grows thicker than before at the point where it was crushed.

Think of it this way; instead of having a two way street for water and nutrient transport, you now have a multi-laned super highway.

If you pinch the main stem it will grow very thick, which will benefit the entire plant. Pinching the side branches will allow you to have more control over how she takes shape. Thanks to the bend on the newly crushed branch you can now redirect it in any way that you see fit. This will also allow more light to reach the lower buds. Since the branch will grow stronger at the breaking point, it will also be able to support more weight. The branches that are closest to the breaking point will also grow stronger in order to compensate for the injury.

The idea here is to gain some control over the shape of the plant while improving on health and increasing her yield. Pinched plants usually grow into very healthy bushes with thick stems. Super cropping is also a good way of getting several main colas. The pinched branches will eventually grow so thick that the plant will treat them as if they were main colas instead of secondary branches.

Super cropping should be carried out during the second or third week of vegetative growth. Take a branch between your forefinger and thumb and proceed to pinch and twist at the same time until you feel the insides start to collapse under the pressure of your fingers. Slowly squeeze and bend the stem without snapping it. Just squeeze lightly until you feel the branch give, then let go. The branch might droop for a while but that's ok as it will heal over time.

Keep in mind that sometimes you will have to keep the plant in a vegetative state slightly longer than usual as it takes the plant some time to repair the broken tissue and redirect energy. Plants are quite good at repairing these kinds of injuries, so there is no need to worry. You might have to provide the pinched branches with some kind of support until they heal or the angle might become too extreme. Regular string will work just fine.

Topping and super cropping both serve the same purpose, the difference being that when you super crop a plant, you don't remove anything from it. You just bend it out of the way. The plant will however behave in a similar way because the main shoot is now lower down than the secondary shoots. The result is that the plant sends up the secondary shoots as if the main shoot was actually removed. The secondary shoots can in turn be pinched and the effect is shifted towards shoots that are located further down on the stem. You will end up with a relatively even canopy which is good because then all the shoots will receive an equal amount of light.

Topping and super cropping should be considered mutually exclusive but a number of the other techniques can be used once they have been applied.

If this technique is applied correctly and with patience, the outcome will most likely be a stronger, bushier plant and a greater harvest. The procedure can be repeated several times during the vegetative stage for even better results.

has anybody tried this in the first couple of weeks of flowering?

anybody know how many weeks and how much jack herer typically stretches?

the girls grew a couple more inches over the last two days... getting a bit nervous

Super cropping jack herer

Super cropping jack herer

I super cropped. Currently they are in the end of the eight week of flowering. There is a sea of buds but they are about knee high at the highest point. Not tall at all.

 

[Dr.Toots]

I stretched the main 4 branches during vegetation with a ticker string and taped the in place to the side of the pot, while also cutting the tip as to prevent tall growing (essentially we forced the plant to be a bush instead of a tree). Then I kept stretching slowly though out the vegetation. The plants are about knee high now, in the end of the 8th week of flowering. FULLLL of buds. Just a seaaaa of buds. But not very tall.

 

[Dr.Toots]

I didn't "super crop" by pinching but rather forcing the plant to have multiple Main branches.

 

[m0ff99]

I got some genuine jack herer newly potted in 10g air pots. cuts were 20 inch tall already and in a less than ideal condition. I expect to top my plants 3 times in 3 weeks of veg before cropping if needed . Scrog is last resort but i do expect a double or triple stretch. Lots of work early on in flower but so totally worth it. Good luck to OP.
