If it's just for one seed. 23 watt 6500k bulb will do. Just keep it 3 to 4 inches above the seed when it pops out. If you don't have a 6500k bulb 5000k will do. Best of luck with your grow.

That depends on how many seedlings and size of the space.

Browning seedling stalk
It's about 3 inches tall and the stalk around the dirt is starting to brown. I am hoping I was over watering and have stopped watering it for 2 days now hoping it will dry out more and see if the color gets lighter. What else could I be doing wrong

Help these babies please! Watering very little when dry with 6.2pH. I can't get these growing. Should I flush? Transplant in different soil? Add nutrients to lower soil pH?

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.

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

When to pot the seedlings?
Hi! When is the best time to plant the jiffy pellets into pots? They sprouted yesterday, and are doing nicely in my propagator. Should I plant in pots now and keep them inside the propagator or leave them a little longer? Or just plant them up & put them inside the grow tent?

Remove Half-Solo Cup from pot, or leave it?
Should I remove the half-solo cup from the pot or leave it? I don't want to hurt any root growth. I plan on topping off the pot with more coco/perlite this week. I used this technique to avoid transplanting.

Stunted??? What to do?
Does anyone think these guys are stunted? I am a beginner grower. They are day 14 from seed, under a Viparspectra 450 on veg mode 18hrs a day. Germination soil and perlite only. Should I bump up the lighting or re-pot them to a bigger pot with soil mix? Any ideas are welcomed.
