Hello The seedling will take light in through the stock at this stage. The light it gets now will stop her from stretching to much. Good Luck. Chuck.

More light now will encourage her to start growing and opening up. I would put her under it now, but careful not to place it too close, seedlings love light but kind of the way NASCAR fans enjoy car crashes-- at a distance.

Guys- I think I have a bad/deformed seed. The second set of actual leaves are starting to come in but they are very small and confused. See picture and let me know if I should scrap it and start over or let it go. Today is day 7 above soil.

What do y'all think about this one? Scrap it or let it do its thing? I did a little damage removing the shell since it was stuck for over 24 hours.

Seedling Height? See diary entries for a better idea.I couldn't find any real answers on this one. How tall should an autoflower sprout be? My Gelat.OG Auto is 2 days old and over 5" tall. I know it's a light issue, but how tall should I expect to see? You know, a reference point of sorts. Thanks!

Abstand der Lampe zum Keimen Hey Grower Ich stehe kurz vor meinem 3 Run und schaffe es bisher nicht das Spargeln zu umgehen. Ich habe eine 150 Watt LED. Beim ersten Mal hatte ich zum Keimen bzw. beim Sämlingsstatus 1 M Abstand und beim 2 Run 75 cm. Wie tief kann oder soll ich die Lampe setzen ? Dankeschön

Curling Cotyledons? 2 day old seedlings.I have seedlings in jiffy pellets and am concerned as the cotyledons are curling downwards. I suspect the pellets are too wet right now and am letting them dry out a bit before watering again. I am following AC Infinity's lighting schedule with 100% light 18/6 @ 36 inches.

Hi All. New Grower here. Just checking in, how're we looking? 70/30 Coco/Perlite. 18/6 light @ 36 inches @ 100%. Canna nutes + Calimagic + Greatwhite. I'm getting some settling of my coco, so I'm adding a bit on top every once in a while.

Hi all, first time grower. I've just put my seeds into jiffy pellets. How's everything looking? I have some of my wife's plants in the tent as well right now. I'm thinking of going 60% at around 24 inches for the first few weeks with this mixed bag. Thoughts?

Seedling tips?New grower. First seed. Seems to be going fine with seedling popping through soil after 2 days. Now under 60w CFL about 6-8 inches above the plant and a clear plastic cup covering it. Any tips for keeping it alive and thriving? Been spritzing with water 1-2x/day.
