Germinating Weed Seeds In Rapid Rooters

Ok,so after weeks of waiting on seeds in mail i decided to go with rapid rooters for seed germination but im not sure on method as ppl.say different things… I don't have good luck with germinating seeds or keeping them alive long enough to grow out. Most of my failures have come in the first two weeks so I am…

Proper rapid rooter use

Ok,so after weeks of waiting on seeds in mail i decided to go with rapid rooters for seed germination but im not sure on method as ppl.say different things. Some soak seeds in glass of water 1st,some use paper towel method then place when tap root shows,others just stick them right in. Can anybody tell me best method for using these.

Best is what works for you.

Personally I soak 16-18 hrs in distilled water. Then stack 4 paper towels on a plate and wet with tap water. Tilt the plate so the paper towels drain. You do not want to see any water just moist paper towel. Place the seeds and then fold over top. Place another plate over top face to face so it kinda seals the moisture in. Place a washcloth folded in half on a tv box and place the plates on top. Within 24-72 hrs should all have germinated. Once they germinate place in rapid rooters tap root down. You should have 100% success rate.. atleast I usually do.

K,thx. Ive always done paper towel method by itself & just put them in soil but decided to go with the rooters but that makes sense. Seems getting the tap root showing before placing would give them that extra push. After waiting weeks on seeds due to flu slowing postal I want as many to germinate as possible.

Starting seeds in Rapid Rooters?

I don’t have good luck with germinating seeds or keeping them alive long enough to grow out. Most of my failures have come in the first two weeks so I am modifying what I normally do in an attempt to get better results.

My new plan is to use rapid rooters and just place the seed in them, then place the RR in a seedling tray, put 1/4″ of water in the bottom of the tray, put on a humidity dome and put all of it in the dark.

The temp in my closest varies from about 80-85*F and the relative humidity is 66% without the humidity dome. The RH jumps to 85% RH with the dome on.

Is 85*f and 85% RH too high and could this cause fungus problems? Is 66% high enough given the fact they are sitting in a 1/4″ of water?

I soak my seed in a glass for 12 hrs, drop into rooter,put little piece of rooter over hole. put nxt to window, at night, under cfl

Sounds like a recipe for cooking rotten seeds.

Don’t use a dome with seedlings, 66% is fine, so is 40. Seeds and seedlings do not require high air humidity level. And don’t put the rapid rooters in a layer of water. Instead add a layer of perlite or hydroton, put the rapid roots on those and water them. Try to keep the temp below 80.

I too soak seeds in (warm yet cooling down) water for 12-24 hours before planting them.

And place them under light.

That’s a brilliant idea! I will do just that.

I read two different versions. Some same put the RR in the dark to germinate and others say put them under light. Even the Rapid Rooter tray instructions say to place them in the dark to germinate.

Why is light so important when the seed is under cover anyway?

Even though your temps are 80-85f in the space the wet RR will be colder and it will likely fluctuate. Putting light (not too strong, I use T8 ) above it helps keeps the temps in the RR stable. But besides that, if you’re already have a hard time germinating, they will likely not all pop the same day and seedling that grow up in the dark become stretchy and lanky (searching for light) fast.

Soaking them addresses both of those issues. If germination fails from improper environmental settings it’s usually shortly before cracking open (too much water, not enough oxygen, and/or too cold/warm) or when it just cracked. The longer that takes, the riskier it gets and the more important it becomes that the environment remain stable. Ideally you measure the inside of the RR for a complete day.

Not only that but you can try for yourself an easy experiment. I had to do it for class but we did Pinto beans and did various hypothesis and tests. Anyway, one of the hypothesis I tested was light vs no light and they were in the same enviorment, one was just in a box without light. The roots were MUCH more developed on the beans in the light. this is them sitting in a moist paper towel inside of a plastic Baggie for 7 days. Soaking them vs unsoaked was also noticible but strangely light outside vs light inside didn’t have too much of a difference. and my outside temps were 90F~ while the inside was 75~

My first grow was a fist fight that I lost. I was smart enough to grow more seed than I needed and finally figured out what I needed to know enough to grow and harvest a few plants. I feel like if I can get my plants to live to two weeks old, I think I’ll have a good chance at finishing them.

I’m been trying to practice on bag seed and not having any luck germinating. I’ve order some expensive seeds and ready to try to germinate them but nervous they won’t germinate.

I’ve tried the paper towel method a couple of different ways and that bag seed didn’t crack. It could be just bad old seed but I’m not sure it’s not at least partially my method.

I’m thinking as soon as the seeds break the surface in the rooter, to plant them in a cup and move them to the tent under CFL’s at 12/12. The rooter won’t sit in the seedling tray for more than a day after they break the surface and won’t grow roots out of the rooter before they are moved.

First, I have to get them to germinate without growing fungus. Sativied’s idea of putting that rooter on top of a bit of perlite wicks the moisture up without saturating the rooter is a great idea. I am testing that right now to see what kind of moisture the rooter will hold and for how long while I wait for my seeds to arrive.

If you guys say put lights over the rapid rooters to germinate, I’ll do it, but it seems counter intuitive to me if seeds need dark to crack.
