stuck germination

OK.... I'm a new grower in need of assistance.  I'm starting White Widow seeds - had no problem getting tap roots using the paper towel method.  Planted in small peat starter pots using Fox Farm mix almost 5 days ago.  I thought I would see something poking through the soil by now, but nothing.... I'm keeping them moist but not soaking.  I've used this method with vegetables before, and usually see veg. by now.  Growing indoors by the way - have them on a heat mat too to keep warm.  Should I be concerned, or does it just need more time?

  • I'm not sure if I got it right. Your seeds had already germinated when you moved them in their starting pots. If I got it right then you simply put 'em too deep into the soil. You should plant the germinated seeds 1/8 inch deep, not more, and cover with a very thin and airy layer of your medium. You know exactly how deep you put them. If you put them 1/2 inch deep they will make it out, it'll take them a few more days but they should make it. If you dug 'em 1inch or deeper, well, I'd put up a small lab to gently "inspect" the pots and see what I can do. Careful, rots hate the light and new baby rots are very sensitive to light and dryness. Therefore keep rots in the light the least possible time and keep them wet.

    As a rule of thumb if after 10 days a seed hasn't sprout I'd inspect thoroughly but pre-germinated seeds should go very little deep and normally in 3 days time they're all out.

    Good Luck with your babies! Keep them warm and in high humidity 70-99%. Use a spray bottle to water them. Keep the close to the light source (otherwise they will grow long to try get closer to the light source and than drop). Don't fertilize for the 1st week. And if the medium you use is soil or has more than 20% soil in it, than it will probably be fine for 2 weeks, otherwise you can fertilize once at 1/4 the dosage prescribed on the bottles. No matter what brand you use. If you follow the producer "chart" for feeding, feed them 1 a week, the other days water.

    Study water (PH, EC, TDS) and how to regulate these values and study environmental preferences for your strain, so that you can try to stay ahead of issues. If you grow in a medium with 20+ of soil, watch out for drainage and salts (TDS=Total Dissolved Solids). Remember that for the first 3 weeks or so your seedlings will need very-very-very little apart from:

    1. Right Temperature and RH range (
    2. Light (keep the as close as possible - if you use a cold light source better otherwise check distance regularly)
    3. Water with correct PH ( and EC (TDS) levels (

    Watch-out for these and you'll be fine. Feed what the producer "charts" say, ONCE a week at normal dosage. Check drainage water for TDS, solids will accumulate in soil and reach high levels. When the Total DissolvedSolids is too high, plants aren't capable of absorbing nurtients from the soil. This means they will show deficiencies and you fed them and can't understand. Well, it's easy. Your nutrients are "locked-up" by TDS. But all this will begin in the vegetative stage which begins when seedlings put their 3rd pair of leaves (cotyledons a-part).

    Good Luck!
