Stringy seedlings

I don't understand why 3 other people just writing the same stuff i already wrote lol ? But at least you know now :P

They are leggy because they need more light. Close the distance between your light and the plant. If you want to toughen them, give them a light fan or when you transplant bury most of the stem. They will be fine.

Stretching (stringy) is the plant growing as tall and fast as it can to reach light. It has nothing to do with the size of the pot. So, repotting will not help. Don't forget. This is a full sun plant. In the wild the sprouts get full sun when they emerge from the soil.

No diary = no information from which we can get an idea of what to tell you about ANY issue! Is this an indoor grow? If it is, I'd lower the lights a bit - they seem to be stretching too much at this stage, probably trying to get enough light. Are they photoperiods or autoflowers? You can transplant photos at any time (although it's not called for here) but autoflowers absolutely hate being transplanted and should always be started in the pot they're going to finish in. Do yourself (and the community) a favor and start a diary... that way, if you run into problems or have questions later on, there will be loads of information we can look at to advise you... Good luck!

Hey Atebano, They are like that because they are searching for a lightsource(the sun or lamps). Since i don't see a diary i don't know if you are growing inside or outside. If you are growing inside, make sure you lower your lamps down a bit. The distance between plant and lamp is different between LED or HPS, look that up or ask me. if you are growing outside there is not much that you can do about them stretching but you can put a fan. A fan will make them move a bit and by doing so, your stems get more firm. I would advice you to keep them in the same pots. Only put them in bigger pots when you are many roots in your medium(soil), You can always at more soil on top so your stems get more solid. Good luck growing :)
