The Seedling Stage; Taking Care Of Your Seedlings

Since you have selected the best seeds for germination, germinated and planted your germinated seeds, you now have plants in the seedling stage. This is the most crucial stage of your plants life. They are small and very fragile and are just starting to build a root system.

Since your seeds have just pushed themselves above ground and shed there jacket all they will need is a little light and water to help them grow. A CFL light will work great for seedlings and small vegging plants. They give off little heat and can be placed very close to the plant so it gets optimal lighting and won't stretch towards the light. Seedlings usually stretch when lights are to far away and have to much of a red spectrum. During the seedling and veg stage its best to use a light with mostly blue spectrum. So when using a CFL light for your seedlings look for ones that have a majority of blue spectrum. I believe cool white and soft white are the ones you want to look for.


Your seedlings wont need any nutrients. They will use the cotyledons (the embryo leaves) to provide it with the energy to grow a root system and the first set of true leaves. Once it has grown a root system the nutrients in your soil will be enough to feed it (adding nutrients could fry your seedling) So when you water your seedlings make sure its plain water that has an ideal ph range (that range should be 6.3 - 6.5 for soil). If your using tap water allow it to sit out for at least 48hrs to make sure any chlorine and other chemicals evaporate from the water. There are things you can add to the water you give to your seedlings but because this is growing 101 we will leave that for the Advanced Growing articles.

So all you really need to do for seedlings is provide the basics. Make sure the grow area is not too hott. A temperature of 78F while lights are on is ideal. You can also use a small fan on low to circulate your air and gently blow on your seedlings. Remember they are seedlings so you want the air to be very gentle but enough for it to move air around. This will strengthen your seedlings, also encouraging them to grow thicker stalks. As your seedlings move into the vegetation stage you can increase the speed of the fan to allow better airflow and give the plants a little more resistance to further strengthen the plant.

Once you notice steady growth and the roots start trying to grow out of the holes you know its time to transplant and get them ready for the vegetation stage and rapid growth.

  1. Thanks a lot, very helpful. What do you think about light exposure times? Should I follow a time-schedule? (I'm using a soft-white CFL @ 10 inches from the seedlings). For watering I use tap, but no idea how to measure HP levels or the proper amounts of water to supply.

    Greetings.

    1. If your in the seedling stage/veg stage I would stick with the 18hrs on 6hrs off schedule. Some growers do 24/0 but I wouldn't recommend that. Many beneficial things happen at night, during rest. If you feel you need to do more than 18hrs on, you can do 20 on and 4 off. But honestly 18/6 does me fine.

      Thank you for your comment/question.

    2. i have been doing a 12/12 schedule and its growing lik, well, a weed. is there any downfall to my schedule?

    3. Are you doing 12/12 from the start? If you are then don't expect fantastic yields and a big plant. You need some vegging times. There are some strains that do good in a full 12/12 grow but most likely your strain is not one of them. I would suggest giving it 18hrs of light until its ready to flower.

      Thanks for your question and stop bye again.

    1. I know I am late on replying to this (I had some terrible things go down in life and could not continue writing) But it sounds like you don't have your lights close enough. Its the classic stretch to the light situation you are experiencing. If you are using CFL light you can put them very close almost touching the plant. Just make sure they are not touching at all. If your using a HID light, use your hand as a marker, when its too hott for your hand, its too hott for your plants. But you always want to get the light as close as possible to prevent that stretch. Sorry I was not able to resolve your problem sooner. But I do thank you for stopping bye.

  3. if I am growing indoor and outdoor, bringin in at night outdoor for the day, growing in pots, how much water does my baby need? anyway to speed this process? they are probably about 3 inches high at the moment

    1. Sorry for the late reply. Sounds like your plants are just starting the veg stage. I really can't tell you exactly how often to water them but there is a trick. Don't just go the the top of the soil. The top could look try, but inches down could still be wett. Stick your finger in the dirt about 3 inches in. If it feels moist, your good to go another day. If its still dry, its time to water.

      What process are you trying to speed up? I am not clear on what your asking.

  4. Hello, I'm doing a small grow (1 plant) and was wondering if Im using the right amount of light I got 4 23 watts 100 watt equivalent(Soft white), my plant is only in seedling atm and I'm only using 2 bulbs atm, will this be enough for veg and flowering?

    1. Hello, thanks for your comment/question.

      If your only growing one plant those 2 bulbs will be good for seedling and vegging depending on how long you veg for. Once your plant gets to a certain size you will see that your plant is not getting enough light coverage.

      If you intend to stick with CFL's through the whole grow I suggest you get a 2 Y splitters. This way you can run all your lights. When its ready to flower the 2 cfl's just wont cut it. Will you grow buds, sure. Will you get any weight, probably not. But if you use those Y splitters and get all 4 bulbs going it will be enough for your plant through flowering. You might only get a quarter ounce but its better than just a few grams. You might even do better than a quarter if you run all 4 under the one plant.

      If you could afford it, I would suggest getting a HPS light. If your worried about electricity and heat you can go with a 150 watt. That 150 watt will be enough to grow a few small plants through flowering and you can get much better yields. But if your sticking with CFL go with the Y splitter and use all 4 lights during flowering, you will need it.

      Hope this helps.

  5. This is my first grow. I planted 3 seeds in 3 different pots of soil at different times. 2 have sprouted an the other one has just popped the seed. I have one cfl 100w. An I'm wondering what more do I need to get an do to increase my yield?? I'm on a 18/6 lighting but not sure how to water my little seedlings. Don't wanna kill them off. Thanks in advance.

    1. Hello Monica,

      Beautiful name btw. Always said if I had a girl Monica would be at the top of the list when it comes to considering names. Anyways, to answer your question...

      Unfortunately your 1 cfl will not be enough. It will get you through the seedling stage but when it comes to vegging your going to need more light than that. However CFL's are fine for vegging, I would just add a few more. What I would do is get two Y splitters, and turn 2 sockets into 4. So you would have 2 separate light sockets hanging, each with a Y splitter. This way you can run 4 CFL lights which will be fine for your 3 plants. Since you are vegging I would use a blue spectrum light, like soft white, cool white. Stay away from using red spectrum (usually called warm) in the vegging stage. Its okay to use one red spec light but you want the rest blue. Also keep the lights as close to the plants as possible. They don't give off much heat so you can keep very close to the top, just not touching.

      Your lighting schedule is perfect. As for watering, the seedlings wont need to be watered as often as bigger plants. Water until you see a few drops coming out of the holes (make sure the pots have holes in the bottom for drainage) Once you see a few drops of water coming out you know its watered well. To check when it needs to be watered, stick a finger in the soil about a quarter of a inch down, if the soil is still moist/wett you don't need to water. If its dry, its time to water. You can also pick the pots up and judge the weight, when they are watered they are heavy, you will notice they will be a lot lighter when they need watering.

      There are many things you can do to increase yield. I would suggest giving me a e-mail to go into more detail. Contact me at CannabisCountry420@gmail.com To briefly touch on what can help yield, you can top your plants, you can also do low stress training, and veg them for a good 6 weeks.

      In the flowering stage you might want to get a high pressure sodium light. If you don't have a lot of money to spend you can get a 150W HPS for under 100.00. Should find them for 80.00. Having a HPS light for flowering over CFL's will greatly improve your yield and quality.

      I would also suggest you read all my growing 101 articles regarding the growing process. Start from the beginning and use the links at the bottom of each post to bring you to the next step.

      Send me a e-mail and I would be happy to help you learn a little more. Thank you for visiting Cannabis Country and check back often for great content and useful information.
