help me germ jack herer!

I have 5 jack herer from sensi seeds germing for maybe 3 weeks and only 1 shows any sing of life.
I used the method i had great success with:the wet paper towel,but to make sure i put them in a warm,26-7 C place.
Im getting a lil nervous,those seeds cost BIG bucks,average folks work for 1/3 months for the price here.I dont even dream of refunds or resend,just ask you to help
so we have 4 seeds,i alredy scarred them a week ago,but nothing.Maybe we have someone here who had the same problem and got solved?any advice is welcome!

ps:i germed many seeds(20+) with more tham 90% success,so none of this is my fault.

problem you have is that you bought sensi seeds.
they have been known, recently, to have lil to no germ rates.
 
weah,i wont do that again.fuck seed companies that sell non germing seeds for 150eur.
i manually removed half the shells,all 5 is live,but simply does nothing.
thanks for the input anyway :D

Er... I have never had a problem with sensi seeds. I can understand why you are pissed because their stock is expensive but I doubt it's their fault. did you buy from them direct? If not, I would avoid using whoever you bought from again - alot of people store their seed stock badly. If you did, I would send them a polite complaint and, you never know, they may send you some replacement seeds. After 3 weeks, I'm afraid, I dont think they are going to germinate - longest I have had is 10 days.

In future, I would caution against the wet tissue method - it isn't reliable. Sorry but I have used itmany times with varying degrees of success but it isn't worth the risk. It's very easy for you to miss the tissue drying out that little bit too much and then it's kaput.

Instead:

1. pre-soak your seeds for 12 hours or so in a very mild solution of hydrogen peroxide, rooting solution and water. The peroxide will sterilise the water and kill off any fungi (second most common cause of seeds not germinating).

2. Then, plant the presoaked seeds in whatever you are starting your plants in (jiffy plugs, perlite, rockwool, compost, whatever). Make sure that you have pre-soaked whatever you are starting your plants in with a light dose of nutrients in pH adjusted water well before planting the seeds. I usually do this when I put the seeds in to soak and tie up the pots (as I start mine in little pots) in a tied up plastic bag overnight, to ensure that the moisture is thoroughly and evenly distributed throughout the soil.

You can find the exact proportions of peroxide to water and a fuller description of this method in Big Book of Buds 2 - probably on this site too somewhere.

btw - Jack Herer (the weed) = pain in the ass. It's always been a pig and I guess always will be. Sensi brought out Jack Flash as an easier to grow but similar alternative.

Good luck, hope it works out for you.

Use Mandala Mikes Rockwool germination method . had 14/16 sensi skunk#1s germinate this way . never had a problem with sensi seeds . they might not be as fresh as some seedbanks , but the majority are viable ime.

some took 3 weeks to surface . the beauty about germing direct in RW imo is zero disturbance or damage to the young taproot . just transplant to your chosen medium when they break the surface .

-----------------------------------------------------------------------

Rockwool: immerse the rockwool cubes in water with a pH of 5.6-5-8. Let the water drip off. Place the seed in a horizontal position into the hole. This is the easiest method. Alternatively, you can also place the seed into the hole vertically with the rounded end facing up. (Cannabis seeds sprout by opening the shell at the pointy end where the taproot grows out). Cover the hole with a small piece of rockwool. Water the rockwool cubes with a weak nutrient solution of 15% and pH 5,6-5,8. Put the rockwool cubes at a warm location. Temperatures at 25+ C accelerate germination. Take care that the rockwool cubes do not dry out or stand in the cold. Within 3-4 days the seedlings should appear out of the cubes.
Once the seedlings appear water with a nutrient solution of EC 0,8. This can be increased to EC 1,0 as soon as the first true leaves begin to grow. Seedlings require sufficient light (this applies to the strength and length of daylight or artificial light) and fresh air to grow.

im glad you had no problem,but do a search,just here on ic.many complains about the quality,dont try to save sensi on this one.

i got the seeds from one of the biggest seed companies,they know how to store.

the towel doesnt dry out.if you keep the humidity high it will stay moist even when the temps are high.i grow shrooms too so the incubation box can help.i can keep a towel in there for weeks and doesnt dry a bit.
its actually the seed shell that is too hard!
i thank you for the advice but as you can see,i soaked for more than 1.5 days(not just 12!).

Did you stop to think that maybe this is your problem? From Mandala's tek on germination:

1. Soaking seeds in water/wet paper towels is a method which can be used for old seeds (3+ years) that are drying up and losing germination power; and for pure land race equatorial strains such as from Africa. Both factors do not apply to our seeds. Fresh seeds have a healthy embryo whose cells are filled with water. But excess water causes the cells to bloat, depletes oxygen and leads to the tissue rotting away before the seed embryo can germinate. Old seeds have lost water in the cell tissue, the embryo starts to shrivel, which is why germination rates drop the older the seeds are. Therefore, old seeds (ie. 3+ years) can soak up more water before adverse conditions cause them to rot. This is one of the main reasons why various seed stock reacts differently to pre-germination methods. Especially novice growers make a lot of mistakes with pre-germination methods such as soaking seeds in water for up to 1-2 days. Even if one chooses to pre-germ seeds it has to be done correctly.

Unless you knew that your seeds were very old, soaking them for that long sounds to be a bad idea. Sure, you might have done it before and had some success, but its possible that those strains were exceptionally vigorous and managed to make it anyways.

Germinating straight into coco might be a better idea. I think there is a good potential for over-watering rock-wool, and possibly with keeping a consistent pH level. Especially with seeds that have trouble germinating, rock-wool might be trouble. This is my experience with one strain that had really low germination rates, compared to several other strains that did just fine in the rock-wool. Just a thought, and Sagarmatha suggested coco over rock-wool as well.

try to offer a little advise , and get told don t try and save sensi ? wtf ?
ya dude , learn to grow before blaming the seed co. :wink: paper towels are for wiping your asre .

47/50 germed direct in RW inc. the sensi sk1s . your experience with RW may vary .



peeez


eta .... to be clear i use 1" RW starter cubes , in a prop. . as soon as they sprout , they re transplanted to pots with whatever medium i m using . these show pots with mapito.

just becouse i ran into a problem it doesnt mean i cant grow.
my first ordered seeds just popped,after 4 years of BAD storage(high temps,no desscicant).these are clearly worse.

2 out of 5 now show some progress finally.the bad grower maybe does it....?

Easy there cabinet boy, we are just trying to help you out!

Your bad experiences with sensi are unfortunate and you may not be to blame but, as justagrower and I have implied, one-off problems with a set of seeds doesn't mean the seedbank are to blame either. This is living material you are talking about, it doesn't always "go according to plan". I wouldn't always listen to what people say about seedbank on this site - people are always slagging off KC brains for some reason, for example, but he's a good seed producer in truth. However, yes, I understand why you are disappointed with the poor showing from your JH seeds. luckily there is plenty of other choice. If it helps, I reckon Paradise seeds probably do a very good job of packaging their seeds protectively: they are sealed in plastic foil bags.

Sirius and justagrower have made some very sensible suggestions about starting seeds (hopefully, I have too). I like using rockwool but I am careful to presoak it for a while in pH adjusted water ; I totally agree with justagrower when he say "the beauty about germing direct in RW imo is zero disturbance or damage to the young taproot". seedlings can be very fragile.

I have heard good things about germinating in coco so you may want to try that, as sirius recommends. Some people rate perlite too. coco and perlite would seem to me to be good choices if you are growing in pots and want to transplant when the seedlings have rooted ; rockwool (or similar) plugs are better if you are transplanting into a hydro rig becuase they are clean and protect the young roots well.

Hope it all works out for you
