Germination and thermostat

[aliennnz]

Hi guys i just have a quick question...
i had some like 20 seeds storaged and i dont know their strain (same seed as my grow journal).
so from the 20 seeds i did try to germ, none as came out the surface.

Some 10 germinated, with half a cm ( 0,5cm) of tail. But after 2 weeks in soil they didnt came up... during daylight i can get 17celsius but i have some light to make it warm, but at nightfal it drops to 15celsius and i heard it is not good for them while not sprouted.

My question is, i have a thermostat that i can use, and i think im gonna use it. it can get to 30celsius!
i've bought 6 seeds and im gonna want to germ them. since my house is to cold im gonna use the thermostat to get at least to 24/25celsius so it gets warmer for them.

should i do it?
and should i use lights before the seedling breaks trought the soil? thats my question for now. Because i've germinated these seeds before with no problemsbut it was on summer, i know they are old seeds probably 10yold seeds, but i think its the cold ruining them.

thanks!

Heating mats are cheap and functional. Lights when it emerges.

Ok thans man! im doing it already, but 3 more days and im putting them down, since in 3 days it gets to 3 weeks without a single movement of the seed... i think they frost 1 week ago ith the 15celsius at night..

For old seeds I use a different technique if I have trouble germinating seeds where I would take a little surgical knife and slit the seed on one of the sides carefully enough to leave the embryo untouched or exposed and the seed still in a viable intact state that it could still germinate and start the germination process over again. Within 3 days I would have a sprout

hi!! i've done it to one of the seeds, and after 1 day she is still the same.. the inside of the seeds looks really good, still white and with a green layer, but 1 day after she didnt move a single bit. I put it on the side of the germ cup so i can check on her tho, but still nothing. Its fine, i just bought some amnezia haze and Royal Gorilla. In 2 days they will arrive and i will germinate them! hope it all goes well

When I put my seeds to germ in their Germination station, I presoak the rapid rooter with a hydroponic root stimulator added to the water and aim for a ph of 5.5, so I'm assuming your using the water and cup method correct?

true that sir! i am, but i dont have any kind of nutes now with me, but i can check the pH nontheless!
thanks for the idea!

but these seeds already been in the water for 24 hours.. im affraid that if shes not dead yet i can kill her by having no air in the water?

I don't think you have to worry about oxygen being in that water. Their is a possibility you can drown a seed, but if it's only been 24 hrs I don't think there's a chance of that happening so soon. Usually for me it takes 2-3 days to germinate and on very rare occasions probably 5 days but not that often. My method is a little different. I never did the cup of water and seeds.

Don't give up on the seed, give it sometime.

so whats your way of germinating them seeds? (i mean usually)

I thaw out my seeds for a day from the freezer. Let them get room temp. I make a water solution with a Hydroponic root stimulant to presoak my rapid rooters for 24 hours pH of 5.5, by the time my seeds are thawed my rapid rooters are ready. I set my thermostat to min 77- max 82. I place my seed in the rapid rooter after shaking off the excess water and place it on the tray that is placed on top of the heating mat. Within 3 days I have a sprout. Make sure the rapid rooter does not dry out or is completely drenched while germinating. If I have a stubborn seed after 3 days I make a cut and while ensuring that the rapid root is not to wet and not to dry.
That's my process for germinating seeds.

For autoflowers I follow the same method but the only difference is I remove the autoflower seed from the rapid rooter after it germinates and before it takes root within the rapid rooter and possibly stunting the growth.

Do you have a thermostat that is connected to your heating pad so that it can shut off and turn on automatically?

If you try to pop 20 seeds and none of them germinated and they look viable, it's something that your doing or not doing or not doing right.

ok got you! ad im gonna try then your way, but probably not right ow since its been hrd to get material because of the virus. years ago when i did grow the same seeds im trying now i simply put them on a cup of water and after 1 day all of them (4) had the tail with 1 cm already coming out. i simply did that and they came out perfect. Now years later i did the same process and none is surviving, or at least the ones that got a tail out, the tail ws less than 1cm and until now they simply didnt grew.. so i beliee at the same time im maig some mistake but the only difference from now and then is the temperature at my house.. i did it at summer time before, and now its freezing, my house is really cold and humid until may. But thats what i dont get, if at least 2 of the 20 seeds got a tail out and stop growing when i put them on soil gotta be something im doing wrong.. either temperature or lights or i dot know. I can creat any envoriment you wat with my aquarium, and i did it, but what it looks to me is that they are dead, but they are still pretty white (the tails), they simply dont grow lol and im talking about growing mm not cm

 

[aliennnz]

i have a thermostat that i can control like that yeah, the oly thing i dont have is a heating pad. I have the aquarium and thermostat because i had retilians before, and i did indeed germinated those 4 seeds years ago in that same envirment i can create inside of the aquarium, this ast 3 weeks they are simpy not germinanting or growing

 

[aliennnz]

i am i frying my seeds? because they are having 23 to 25 celsius a day... maybe i should be germinating them at 18celsius?
at night my house drops from 10 to 15 celcius and during day is 17/18celsius

You said when you put 2 of the seeds in soil they stopped growing. What kind of medium are you using and was it pre-fertilized? If so it might be too hot for a seedlings.

No you are not frying your seeds at that temperature. I germinate 77-82f

being honest this one is not fertelized, but years ago was not fertelized as well, im using the same dirt i used before. But thats the problem maybe.. i've never invested siruously to grow cannabis. maybe i should invest, and maybe my dirt is bad.. and yeah probably to hot for them
