Slow Growth or Normal?
Hey all. First time grower, so apologies up front for the beginner question. Popped my first seed 2 weeks ago in solo cup with BAS3.0 . It finally came thru the soil last week (first picture). Fast forward a week and the growth seems slow(?). I watered with recharge once last week. Checked PPFD and it was around 100. I increased it to 150. Measured with Photone and diffuser. VPD is hovering around 1.0

Back in the day I had a bunch of seeds I overwatered and the soil didn’t dry out quickly enough. They never really grew much. If your soil is good I have no ideas. Good luck✌
-
Over-watered seedlings are almost always stunted. They’ll typically need watered only twice in a solo cup the first 10 days or so. At that point the seedling should almost be big enough to come out of the solo cup within 2 weeks with a decent root system.

Something that I had to learn and I’m still learning. That BAS 3.0 is a nutrient rich soil and it takes some seedlings a while to adjust. The 3.0 is built to be a water only product too. Especially the initial run in my opinion.

Sounds normal to me use some recharge it helps with the root production
-
This is what my seedlings look like on day 10 after spouting!

Honestly thought they should look something closer to this. I’ve seen no real change in the last 3 days. I watered the bag of soil with recharge, if i grabbed a handful and squeezed, i didnt get a drop but my hand felt wet so i figured that was enough. Loaded some soil into the cup, planted seed and covered with a clear solo. And rewatered with recharge again a week later (maybe a shot glass amount). Nothing since.

I water with a spray bottle until it looks wet and then I water again when it looks dry and the cup gets lighter than it was after I watered it!
-
Going to start another seed in the meantime. Give this one a few more days to see if it recovers. Hopefully i dont kill the next one. Lol. All part of the learning process i guess
-
I’m having the same problem but different soil. “Black Gold” for seeds. First timer here as well so I find your question interesting. If you find out anything let me know please.

what are your temps and rH?
VPD around 1 kPa can mean 86F at 65% rH or 68F at 45% rH
-
On/off set points for heater and humudifier are 70-75F and 64-68% RH. I was taking my VPD reading off the AC Infinity controller which was off. Last night i verified temp and rh using another calibrated unit from work (benefit of working in a lab). So i guess my VPD is fluctuating between 0.6 – 0.9
-
for that early stage I’d raise the temps a bit over a couple of days. they are in the general zone but at the lower end of the zone
