Why are my seedlings so leggy when they get enough light?
JohnSwaggartstarted grow question 14 days ago
I added pictures from 4 days after germ and wonder why my seedlings are so leggy (~5cm). I already filled it up with soil and they would be 10cm by now if I didn't. First 2 days was 12-14 DLI and since yesterday am giving them more light than many guides say: 250-270 PPFD, 18 DLI

Hey, a little bit of stretching is normal under SanLight LEDs as they emit not so much blue but more red in their light spectrum. If it really would have been 10cm long by now without adding soil on top, you may have had the light a little too far away for the first 2-3 days...it should be fine now with the adjustments and start to make bigger leaves while slowly getting bigger with the stem thickening. A good indicator is the color of the stems, they shouldnt be too light in colour, thats when you dont have enough light.
Good luck!

some seedlings want more than others, but also use developing stem between nodes as a guide... if you give too much they remain tight. too little the stretch out too much etc...
your stem isn't a pale white, so i'd say it's okay. Maybe it's just ready for a little ramp up... slowly.

For me, the first week of seedling stage, I keep the PPFD around 175-200, and then I'll up it to 200-250 PPFD. I don't think your seedlings look leggy, personally. THat's about the average stem length for seedlings. I've seen some leggy seedlings, and yours aren't it. Good start on your seedlings man. Just make sure to not overwater and they'll thrive.

Help with seedlings falling over and dying :/Could someone please look at my two seedlings and tell my why they are falling over? I planted four golden goat seeds, which all sprouted. However, two have already completely fallen over and died. The one with the makeshift supports was completely flat this morning. Thanks

Watering seedlings queryHi there,
How much should I be letting the coco dry out for these seedlings?
I just had a failed grow due to overwatering the seedlings and I'm looking for some guidance.
I know there's many factors, but I'm just worried I'll either under or over water again.
Thank you!

Lamp distance from seedlings? PPFD uploaded in this weeks photos.How far away I should have my lamp from my week old seedlings? I think it has something to do with the PPFD for my lamp (TS600), but I have no idea what it means. The lamp is set right at the very top of my tent now and is 32 inches (81cm) away. See photos in week 1.Setup. Lighting

StretchingBecause my seedling stretched a little during her first few days of life, is it safe to bury a small amount of her stem in the substrate when I transplant in a week or two? I'm using coco and perlite 70/30. Actually writing this down made me realize it's probably a stupid idea 🤣

This is my first grow so I'd like to be sure I'm not missing anything. Does my seedling look alright? This is about an hour or two after her first transplant. I'm not experienced with spotting nutrient issues so would appreciate some experts casting there eyes on her! 🌱🔎👀

Should I wash the potting soil mix before sowing?Going ahead with my first grow. Should I wash the potting mix before to remove impurities and dust particles, before I sow the sprouted seeds inside? The potting mix contains Coco Peat, Perlite, Organic Manure, Seaweed, and other beneficial microbes. Advice would be appreciated!Other. General questions

Should I be worried about the slow growth of my seedling?I'm not giving her too much water at the moment, she's definitely growing and I'm conscious it's only been 3 days since she was put under grow lights but thought by now we would have had more growth

Solo cups vs clear plastic cups for seedlingsI'm gonna plant sprouts in solo cups, but thought it might be cool to use clear plastic cups (to see when roots reach the edges). Would it be bad to use clear plastic cups? Maybe the roots/soil won't like the light idk?Week 12
