Sativied's Picture Journal

Question? have you heard of plants taking longer to finish under led lights? My plant are 7 weeks in, normally an 8 week strain but no we’re near done, these plants are gonna go at least 10 weeks at this pace. Same plants under cmh or hps finished in 53-56 days a few years back, I don’t know

I had ice from nirvana was a great frost plant with a fuel like smell. Beautifull plants and very close node structures. How the f u do it? Great

Same used to grow the nirvana ice was one of my fav of all time. Was hoping to find out sensi was the real ice. Guess nirvana just made something special back then. Looking at white label white ice or sensi ice. Indica crystal extreme.. wonder if nirvana ice is still the bomb...

Thanks man. Not happy with 2 or 3 plants being finicky but considering the climate is bad right now I can’t complain. Temps too low, and barely enough ventilation. Will fix that before switching to 12/12, going to pinch and chop and tie down some branches and leaves and then veg a few days more.

Using warm white leds now instead of the blue-ish hpi-t, thought they stretch more. I’m sure they will soon, the Pan x SH gets pretty tall like both parents.

Here‘s a pic from the mother, Panama (ace seeds). I’ll be shocked if I get similar results now. Main reason I got more plants than I normally would for this space is that I expect things to get ugly.



This is OTH (Old Timer’s Haze, which is basically Original Haze), about as stretchy as hemp.



The advice some give in Ace Seeds’ thread about keeping it short (nother forum) is the opposite of what I do. One of the main reasons for stretch isn’t vegging too long, it’s vegging too short. Plants from seed should ideally be mature betore switching to flower schedule, i.o.w. they should have pre-flowers before flowering. I make macro photos to sex plants, usually from the very first pistils it creates on usually 5th node.



It’s also why I don’t top them earlier and/or just bend them over, takes longer to sex and find males. Besides the pck cross, only plant I don’t know if female/male is the accidentally topped plant.

If you switch to 12/12 before they are physically mature, they will still first mature, stretch, basically vegging with lack of light hours makes them stretch for light, and still take as long to switch to flower. Mature plants, and clones, transition much faster. I do end up with big plants, but not because too much early elongation between nodes. Crowding definitely causes stretch, but right now I remove males around the same time the females need the space.

Good advise, I think my panama was from ace to, never looked as nice as yours though!

Missed this post. It’s certainly possible it has an indirect effect because of the different spectrum, maybe temperature too, but then between cmh and hps is already a good difference. I’ve done literally only a couple of led grows myself but haven’t noticed a major difference aside from what‘s expected with less light. I can already tell the 330watt I use on 2x4 feet is plenty, did a couple of 600watt hps grows in similar size closet.

Did you veg them for a shorter amount of time, did they transition slower?

Quoting myself here from 2015 ‘nother forum, not sure if relevant, it’s pretty much what I mentioned in previous reply.

It's the ontogenetic age that matters, which is about going through all phases from fertilization as embryo to fully flowering, and some strains (genetics from equatorial origin) won't be rushed as much through those phases by setting the light to 12/12. When you grow a sativa from seed on 12/12 from start for example, it won't actually work on the transition to flower stage while it's still seedling and maturing (and will actually progress slower through those initial phases). When you take a clone you have a head start ontogenetically (carry on some of the maturity level) so they tend to transition faster. Unless you reveg or rejuvenate (tissue culture), which is like ontogenetic time travel

If you recognize and look at the stages it becomes easier to determine if and what stage is slower. For example, a couple of pistils doesn’t mean it’s flowering yet and setting it to 12/12 doesn’t mean it started flowering stage. That makes it harder to tell the difference between different grows if all other factors aren’t equal. Low temps can certainly stagnate the processes, an issue less likely with cmh/hps.

I got these pc fans on the heatsinks on top of my leds, they blow heat upwards. Which would be great in summer, blow towards the carbon filter+exhaust. Right now, I wish I had added some U-pieces I could attach on top of the fans to direct the heat down and create some airmovement too… might just have to ductape a piece of flexible ducting on each.

Almost felt bad pinching and bending this one over, PanxSH #1





I wasn’t planning on making seeds but looking at some of the PanxSH and the PF1 and PF4 already know I am definitely going to drop some pollen on a few flowers. The goal with P was to create a piney haze hybrid. Unfortunately, the cannalope haze (version 1, which was supposedly just a c99 pheno) wasn’t hazy enough. Easiest way would be to use SSH but what’s the fun in that… that’s why I grew the original haze and silver haze. The SH from sensi is unstable af but the panama x SH is looking good again and begging to be crossed with P.

Another PanxSH


Final selection. From 25 seedlings to 12 females, 2 males, 3 undetermined. Funny how the sh x pck still doesn’t show sex, it’s barely an 8week strain while the SH and Pan are 9-11wks.

Everything looks great.!
i vegged my mothers for 1 week after I was sure they were female, probably 12 or 14 weeks all together. clones rooted and vegged for 2 weeks then flipped to 12/12. As far as light, I went from a 400 watt hps to a 315 watt cmh, but now I’m actually running a 400 watt led so as far as wattage plants got a small boost, however the light spectrum as you said is completely different between the lights. I used to veg under different lights as well, when running hps in flower I vegged under metal halide, when blooming under cmh I had the higher k value in veg then the regular I think it was 3200 k Phillips master bulb in bloom. Temp may also be something as it’s cooler in my room now it says bewtween 68-72 f other grows may have been during the summer when I keep my temps between 72-80* f

I always liked how hps gave me a good temperature range at least when light was on. Roughly 76f now with 300w led, smaller closet, but it will drop starting tomorrow when I put in carbon filter and turn on larger fan. Freezing outside so I got to pull air from indoor, not good for humidity. And indoor isn’t very warm in that area of the house either, I can see my breath… Definitely different from previous runs. Fortunately roots in perlite seem to handle it better than in wet dirt.

68-72f is not great but doable. However, how much colder is at at night? Mine drops below 60, which I’d normally avoid but I’m just going to roll with it. Quite a bit variation in flower times in my P1-F1 and the PanxSH crosses already so it’ll be hard to tell if it takes longer to finish.

What’s the spectrum of your led? Just curious. A sure way to find out if that’s the cause would be to do a side-by-side.

I’d love to do a side by side but I’m almost done for this year and I only have 1 veg room(closet) 7 ft x 3ft with a 2x4 flood table. My bloom is the room w a 4x4 flood table. My rooms are on a temp controller so In winter it never goes below 65*f and never above 78*f,,,during summer I have it air conditioned to keep cool but pull in outside air every 4-5 hours. It’s cheaper for me to grow during winter months but I have a surplus of weed right now.

Totally understand space limitations. I chose the worst month to grow. Government put a cap on skyrocketed energy rates (electricity and natural gas) but it won’t start till Jan 1st. Still worth it but whether I get 200 or 400 gram isn’t a concern right now, instead of a surplus I have zero stash so I buy. Definitely going to start another grow after a short break. In spring I can suck in outdoor air 24/7.

Just cleaned up a bit. I’m so lazy, closet is getting build while growing. The room is dark so no worries about light coming through.



Looks like 14 or 15 females out of 25.

One of the SHxredPCK is a female, will keep it in separate pot, might make good photo op with red buds.

The accidentally topped one is still gender neutral…


Triwhorled so more places to check for pistils but none so far


Switching to 12/12 today, a week later than planned I think mostly because I didn’t preveg them in dwc to have enough roots to reach bottom of bottle.As soon as they did they took off, fattened stem and grew larger leaves as if container size is no limitation.

I haven’t had to buy weed since the 90’s thanks to growing,it was illegal then but it was a great extra income. Now I grow strictly for personal street prices are crap anyways. If I get a half pound per grow it lasts quite a wile as I don’t smoke to get really blown, just a nice painfree life style.

Things got a bit risky here for a few years. Still is but lower priority to harras small homegrowers. Basically getting caught here in NL means trouble for future housing opportunities, buy or rent. While the housing shortage and pricing is already insane. Main reason I started a grow now is cause I want to smoke my P cross but having too much fun to quit again after this run.

Just isolated the window in the room where grow closet is. Stayed above 60f. Warmer weather expected next week. So far they all seem to be holding up but the SHxPCK clearly is less bothered by it all.

Ladies responding well to the pinching and bending. Again the handles on the jugs turn out to be handy



SH x Red pck:

Accidental topped P-F1. Left it in small bottle, triwhorled, not cleaning it up on purpose




SH x red PCK, also in small bottles, untopped, natural structure




Pretty happy girl




Slow but steady. Hopefully some more flowers next update. Although run off varies, they all get 700-800pm, I just drain the ones with low ppm run off a little extra. Ph varies, rarely below 6, rarely above 7, I just add a few drops to lower tap water to 6.5 roughly. Weather‘s been mild, no more freezing temps outside.

Happy holidays too all!

Thanks man, you too, have a super 2023!

Good stuff, man I love SH. Hands down the best smoke I ever had in Amsterdam during the 90's. You say it's not stable, as in a lot of pheno variation? Have always been interested in picking up some from Sensi, but unsure how many I'd need to hunt through to find a good example. I'm Ok with trying my hand at 14+ week sativas.

Damn, I love sativa too but hate running 14 week strains. I have a haze I crossed years ago with a top44 pick cut the stretch and finish to an acceptable 9 weeks, haven’t grown it in a wile but it held on to the very uplifting almost trippy high.

Haha well I am only just "Ok" with it. I say that after recently finishing some 12.5 week plants with every leaf fried to a crisp.

Every thing looks good Sativied... hope you had a good xmas and a great new..

I still buy SH occasionally at a shop that’s been growing and selling it from clones for decades and it tastes better than what I grew from Sensi seeds. Aside from variety in taste and flower/finish time they get pretty tall with some plants producing clearly more dense/commercial bud than others. Always tricky with sensi, I like them for historical reasons, and hard to skip as a candidate to search for classics. At the same time, we all know they don’t have the original parents anymore. At best you get part of the genepool.

Instead of a 14 week sativa, find a fuely afghani like a hashplant indica and cross it with a spicey SSH (from mr. nice) (with a desirable structure and flower time) and cross the result back to that SSH and you won’t get SH but likely better and closer than a few bags of SH from sensi can produce.
