Purple Seedlings

[FriendlyPharmacist]

On Sunday, September 4th I germinated 8 seeds. On Tuesday, September 6th, 5 of the 8 popped and were transplanted into Black Gold Seedling Mix. Today is September 8th and all five are above soil and looking pretty good.

My only concern is noticing they have purple stems starting from the soil upward. Is this normal for seedlings?

 

[Bose]

Yes nothing to worried about.

 

[Bose]

They look healthy

Good ol papwr towel method? How long did it take to germ?

Looks great. I popped 9 seeds on the 5th, 8 of 9 are out of the ground. The 9th is taking its sweet time. Not sure if it's the strain, never grown 7 of the 9. That last one is The Black from BC Bud Depot. Maybe it's something do to the dark strains?

Bose do you use d2jsp?

Bose, I used the paper towel method. Seeds in a damped paper towel. Paper towel on a glass plate. Glass plate on a seedling heat mat. I put a humidity dome over top to keep them moist longer, just in case I wasn't home in time.

The seeds that germinated did so really quickly. They were started around 5pm on Sunday and by 12pm on Monday they had ½" taproots!

Today marks 7 days exactly from when I started germination.

Maybe I'm being overly cautious but it seems like something is wrong already. Some of the plants have a lighter shade of green around the edges. Hoping it doesn't turn yellow.

Currently under a 1000W MH lamp set at 500W which was 26" from ground. I just raised the light to 48" from the ground in case they were getting too much. They are inside of a humidity dome as well. Humidity holds steadily high which I believe is preferred.

Never put seedlings in a humidity dome, leaves need fresh air to breath, big mistake!

[Kingrow1]

Yep they look screwed from the dome!

 

[Timothypaul26]

Not sure if your model has vents, but they help greatly. Mine has adjustable vents on the top, and after they've popped through the soil I'll open them up. You can always cut or drill a few, or just take the lid off entirely

I have zero idea why anyone would want to keep seedlings in a humidity dome, once you understand how stomata work you will discontinue the dome. Domes are for clones not seedlings and anyone who tells you differently is mis-guided....!

Agreed, no dome is needed for seedlings, just newly rooting clones. I wouldn't worry about the purple stems just yet. 500w is also quite a bit of light for small seedlings, that could be an issue you are seeing too.

 

[FriendlyPharmacist]

Dome has been removed for about 24 hours. Plants have also been about 48" from the 500W light. Temps are steady at 79 and humidity has settled at 39%.

I can't tell if the leaves have changed color but they're now perfectly flat.

 

[Kingrow1]

Where is your humidity meter, if its directly under the lights move it to the side or keep it shaded. This should up your humidity even more...

I still think that's the best method out there

 

[FriendlyPharmacist]

Well things aren't looking so good.

I noticed a fungus gnat a few days ago. One plant is already dead...

My other four plants are still hanging on and I'm hoping they continue to mature. I waited about 14 days before watering them after the soil was finally dry. The leaves were starting to fall on one of the plants and that was enough of a sign for me! Unfortunately now the leaves on all of my plants are curling under a bit. One is curled severely.

Yeah gnats are now fun hmmmm.. The purple might be from cold temps what's ur temp when lights off

 

[Timothypaul26]

Get some diatomaceous earth, that should help keep the gnats in check. Letting the soil dry totally probably killed the plant, you need more than 10% moisture to keep the plant alive, soil will retain some amount of moisture that the plant can't absorb. If you see the leaves start to droop, and top inch is dry, then water.

I planted my plants at pretty much the same time, just moved them into their 5 gallon homes last night.
