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.

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.

Abnormal Seedling?
First time grower, does this seedling look ok? First true leaves looking short and slightly curled. Seed popped last Thursday 1/14. Using buildasoil v 3.0 and watering two shot glasses worth of water ph 6.5. Just want to make sure I shouldn’t be doing something else.

From germination to big pot?
I transferred my auto seedlings in their plugs to a small, transitional pot. Is it true autos can and should go straight from germination to the big pot without a stepping stone?

How long until seeds sprout?
I’m worried about the seeds sprouting had good germination on all four seeds with the paper towel method. planted root down and watered and put humidity domes now just waiting. How long does it typically take for seeds to sprout from soil?

Seedlings under the sun
Does anyone knows what is happening with my seedlings? I placed them today for the first time under the sun. I thought they were not getting enough light. When I went to check on them they were all wilted and fallen over.

Seedling Stunted
Week 2, day 16, the first plant to sprout (Green Fire) still only has it's first leaves (day 8 with cotyledon's). Other plants (separate strain) have now sprouted and surpassed the Green fire in terms of having true leaves. What's going on here?

Time to transplant to defenitive pot? Auto strain.
Anyone knows when to transplant to definitive pot? What is better, wait 2 week after germination (so 1w more) then transplant to 14L pot or transplant now... I'm opened to any experienced advises and suggestions. 😅

Any idea whats wrong with my seedlings?
Hey everyone, I had this issue last time already when I popped about 40 seeds and had to discard more of half of them because of this issue. I pop them as usual in water and put them in my living soil 0,5L pots. As soon as they show on the surface they look like shit... any idea?

Should I continue to veg?
I am now in the 5 week of my plants and we had a very rough start with nute burn and discrepancies with amounts. They have recovered nicely but I think they got stunted except for like 3 of them. Today is water change day and I'm wondering if I should go into bloom like this.

please look at my seed 3 days after germination and tell me if she is a goner
my germination pot fell while being moved. one seed got out but it wasn't rooted yet, I put it back in. do you think she will be okey or do I germinate another one? I damaged the tip of the root when putting the root in the hole.

seedling discoloration, leaning toward center, brown perlite despite no nutrients so far
leaves of these seedlings look weird, almost looks like light discoloration, but they also seem to be leaning toward the middle of the box for more light. Also, the perlite is turning orangey/brown, just got a new light and dont have much experience with LED or growing in general

Is growth normally this slow for seedlings? Any advice appreciated.
These 3 seeds (of 12) germinated March 19-21; I transferred them to coco coir/perlite soil under 40W full-spectrum grow lights I also use for garden vegetable seedlings. Lights are on 16 hours; off 8 hours, and the seedlings have barely grown in the last 10 days. Is this normal?

Wrong pot D:
Ive sadly placed my seedling in a pot without any drainage holes at the bottom, how bad is this? I know I need to be careful with overwatering , obviously in 10-15 days when it starts vegging properly Ill transfer it into its final big pot that does have drainage holes.

Adding More Soil
Should I switch from fabric pots and add more soil or just add more soil? My plants are a tall in the sense of they seem really stretched up. I moved my light closer, but I think the lack of dirt could also be hurting them. Any ideas or recommendations? And I'm using a soil/coco
