Day 0: Feb 09, 2021
Soaking seeds 12-24 hour in 500ml H2O + 3ML GS Plant Food Organic Liquid Kelp solution.

 

Day 1: Feb 10, 2021
After 14-hours of soaking in darkness, seeds have already sunken to bottom of solution and tap root is starting to emerge from each seed. Temperatures averaged 75F. Moving the seeds to tray with paper towels moistened with the soaking solution and will leave in darkness for another 24-hours or so.

 

Day 2: Feb 11, 2021
After ~24-hours of germinating seeds in paper towels, a healthy tap root has grown from all 10 seeds. Carefully moved seeds to root riot plugs. Also shredded an extra riot plug to lightly cover the seed holes to minimize light exposure to the roots. I did feel a small pop when trying to lightly tap one of the seeds into the plug. Fear I may have snapped it's root... Well, only time will tell.

 

Day 3: Feb 12, 2021
Temps have held around 72F (Low) and 78F (High) over the past 24-hours with humidity in the propagation dome ~60%-75%. Mixed a light solution with 500ML H2O + 1ML Liquid Kelp and applied 10ML of solution (PH ~6) to each plug. Noticed a few seeds started to poke up slightly above the seed holes. Hoping to see some cotyledons in the next couple of days.

 

Day 4: Feb 13, 2021
Several ladies decided to show themselves and start stretching their arms today
Temps have stayed 72F (low) - 76F (high) with humidity (60%-70%). Unfortunately, I suspect the seed I felt pop when placing in the plug likely severed the root and probably isn't going to sprout. Unfortunate error on my part. She had the longest root of the bunch. We'll see over the next couple days. A couple are lagging the other girls but trucking along. Plugs are plenty moist. Just lightly spraying dome to keep humidity up.

 

Day 5: Feb 14, 2021
All 10 ladies have sprouted. Two are still catching up. Several had roots running a few inches out of the riot plugs into the tray. Went ahead and transplanted to 1-liter SuperRoots Air Pots with 70% Coco Coir / 30% Perlite mix and added endomycorrhizal fungi to support root development. Conditioned medium with 5.8ph water with cal mag only. Added a second small 32w LED and decreased distance of lights to minimize stretching. Temps have ranged from 72F to 78F with humidity 50%-70%.

 

Day 6: Feb 15, 2021
Ladies are doing well. 8 Girls are looking healthy and strong while 2 runts are struggling but still pushing along. Medium is sufficiently moist, no watering today. Frequently spraying dome to maintain humidity. Temperatures have ranged between 72F - 78F and humidity 50%-65%.

 

Day 7: Feb 16, 2021
Unfortunately they stretched alot the other night. Lowered the lights to just a couple inches above dome. Girls are progressing nicely. First set of true leaves are filling out. Two runts finally opened up and are slowly catching up. Seems the seed I was worried about may be fine after all.

Mixed a light feeding solution:
1 Gallon H2O
5ML CalMag
2.5ML Buddha Grow
2.5ML Trinity
2.5ML Surge
3.0ML Ancient Amber
PH 5.8

Watered until runoff (Approximately 150ML per pot)

 

Day 8: Feb 17, 2021

These girls are Virginia Slims. Added support to some of the seedlings as they rocketed to 3-4 inches and are skinny. Hopefully having the lights closer keeps them from stretching anymore. Removing the dome and have a small fan blowing on them. Main room isn't quite ready and current room is pretty dry. Using small humidifier in the meantime. Coco is still plenty moist, no watering.

 

Day 9: Feb 18, 2021
Looks like ladies have stopped stretching thankfully. Kept humidity dome off with a small fan blowing lightly across them. Temperature has ranged 68F-74F with humidity 40%-50%.

Mixed feeding solution:
1 Gallon Purified Water
5ML CalMag
4ML Buddha Grow
4ML Trinity
4ML Surge
8ML Ancient Amber
PH 6.0

Watered until runoff (~200ML per pot)

Day 10: Feb 19, 2021
Ladies appear to have stopped stretching thankfully. Medium is plenty moist, no watering today. Temps have ranged from 68F-72F with humidity 45%-50%.

Finished setup of Mini-split, Electrical, and 5'x9' tent today for main room. Will finish setting up controllers, lights, fans, etc tomorrow and hopefully move them into main room this weekend.

 

Day 11: Feb 20, 2021
Ladies are growing slowing but surely. Temperature has ranged 68F-74F with humidity 40%-50%.

1 Gallon Purified Water
5ML CalMag
4ML Buddha Grow
4ML Trinity
4ML Surge
8ML Ancient Amber
PH 5.8

Watered until runoff (~200ML per pot)

 

Day 12: Feb 21, 2021
Finally got the main room mostly set up. Went ahead and moved the seedlings to get better climate control. Just have to finish setting up a few more fans, water and air pumps and will be done with room build.

Girls are doing well. Medium still plenty moist, no watering today. Temp has stayed between 68f - 72f and humidity 45%-55%. Put them under a better led light and different room.

 

Day 13: Feb 22, 2021

Everyone is doing well. Temps 68f-72f and humidity 50%-60%.

Mixed feeding solution:
1 Gallon Purified Water
5ML CalMag
5ML Buddha Grow
5ML Trinity
5ML Surge
8ML Ancient Amber
PH 5.8

 

Day 14: Feb 23, 2021

Girls are doing good. Temps staying constant 68F with humidity 45% - 60%. Medium plenty moist, no watering today.

 

Day 15 - Feb 24, 2021

Looks like girls are showing early signs of nutrient burn on tips of lower leaves. Also some spots that looks like could be calcium deficiency.

Flushed with PH 5.9 water and CalMag (6ml / gallon) to be safe. Going to increase PH to 6.2
next feeding with 10% reduction in nutrients. Also raised light slightly.

 

Thanks! Been a busy couple of weeks
