Larger containers have a higher water-holding capacity making it easy to drown tiny seed spouts. After the seed sprouts fill up the dixie cups one can up-pot into 1-gallon pots for up to 4 weeks. After the plant shows the sex, it can go into a large flowering container. Here are some plants going thru the 3 container-size containers.

Nice healthy plants.......do you have to throw soda cans on the floor...? ;). Checking/writing the weight down of cups might be a little time consuming, a good idea for beginners, but in time you can get more of a feel for water needs. You've found a system that works for you, no doubt........in this case of the 20yr old seeds, it's a special situation. It sounds like you have 3 transplantings until you flower? It seems like quite often even with smooth transitions, there can be a bit of a growth pause, if the roots start getting just a little bound, and for a few days after transplanting.........I think people who go directly into the one and only container they use for the entire grow (5-7 gal?) at least keep that balance of water and aeration.......slight drying out in between waterings as they get bigger....it takes good, fluffy soil, and that intuitive experience to get that right, the reward being it saves a lot of work and avoids growth pauses.

Did you mention your variety? ;)

I think this might be the only one that's gonna grow out of this batch. I'm ok with that, I've got some more.

I start seeds in these cheap thin 4-5 inch planters. Watering isn't a big deal if your soil drains well and you use some common sense. Once mine start needing water every day abouts, I put them in 5 gallons as a final container. I've got some other threads growing, check em out.

My buddy says he only saved the seeds because it was kill. He said the small dark seeds are from a Thai variety, chocolate Thai maybe, very spacy. The others are bagseeds from fire that he got 20+ years ago from Utah to Alaska.

That awesome. Hey it's not like 20 yrs ago was 1977........but why not try to pop all of them all at the same time? Especially if they're mixed and you don't know what's what? It would increase your chances of saving the genetics. Any 1 male and 1 female would at least allow you to carry on.......

I've got plant count requirements to think about. I've been trying to germinate 6 at a time. Once I repot the plants in my veg tent and move them over to the flower tent, I'll be trying to germ some more of these old seeds.

I'm hoping he gets 2, one of each......actually if he's gonna space them out it would be better if the first one is a male, he can save the pollen. If they're 2 different varieties he could get an interesting hybrid (Thai plus an Indica dom hybrid?). Then he'll have new seeds he can name after his friend.

Maybe keep it in veg long enough to cut some clones off of it just in case things go south along the way?

I definitely want to keep any of these that germinate. I'm not going to let the old genes die off, and I'll of course need help with that. I grow for personal use and don't breed cannabis, so I'll be more than willing to share my findings in these seeds. Clones, pollen, whatever. I want to share with people who appreciate conservation and preservation.

I dug through the top layer of the pot looking for any more germinated seeds that might be having a hard time. I didn't find anything, so I assume the rest of the seeds in this pot are dead, I moved the lone ranger into the center of the cup very gently. One healthy looking baby out of twelve of these old seeds so far, I'll be sowing some more tonight if I can't sleep.

If you weigh the dixie cups you will have more success with the germination rates. Another critical thing to remember is the seedlings need a gentle breeze after sprouting for transpiring nutrients and water.

I appreciate your enthusiasm. I am a simple man, weighing and tracking cup weight throughout a plant's lifecycle sounds like a special torture to me. I just grow the dang things. No notes, no measuring, no sir.

I do agree with the breeze thing. It helps with stem rot, lowering the humidity where the seedling meets the soil, strengthens the stem fibers......
