Stage - Seedling: Day 1 - Total days above soil 6

Today's update. High temperatures will be 106° F (41°C) with humidity at 8%. And this is still April.

I now have 4 plants above ground. Two of which are 5 days ahead of the other two.

The oldest two that were put in Jiffy pellets are finally out of the germination stage (at least by my definition) and have achieved the status of seedling. These two will be transplanted today into Coco/Perlite Solo cups. I was worried about these two but it looks like the roots are doing well.

Stage - Germination: Day 5 - 2 days above the soil

The younger two are looking good. I still think they will catch up to the first ones.

I'll update after the transplant.

Successful transplanting of the two seedlings.

I added 2 ml of Core A and Core B of @Prescription Blend to a gallon of 0 TDS water and a PH of 6.2. Total TDS reading of the final solution was 165 ppm. Then I added a small amount of Great White Mycorrhizae to 8 oz of the nutrient water. After transplanting both got about 3 oz each.

They are now both back in their tent. I will keep them under the dome until they reach the veg stage.

Looking good!

Stage - Seedling: Day 3

Today's temps will reach 101° F (38°C) with humidity at 28%.

I currently have the lights set for 18/6 and increased to 50% power. My meters read 20000 lux or about 350 Par at 28" "inside the dome" which filters a little bit of the light. Due to the heat the off hours are between 12:00 PM and 6:00 PM. When the lights come on at 6:00 PM I give each plant 25 ml of nutrient solution which is about 5% of the solo cup capacity and should produce 20% run off. I water around the outside of the root ball area. I watered last night and the Coco is still saturated so I won't water again until 6:00 PM tonight. My goal is to keep the Coco above 90% saturation. Tomorrow I will up the watering to twice per day.

A few updated photos.

Number 1 and 2 are the original seeds. Germinated 8 days ago. Numbers 3 and 4 were germinated 3 days ago. As I predicted number 3 will out pass number 1.

3 and 4 already catching up. Good job

Looking good, Dano!
They'll be huge in no time.

Thanks Tk

I learned a good lesson with those Jiffy Pellets. They can get too saturated and can suffocate the seed. These two were lucky and are just now getting back to normal. Both pellets had a lot of roots coming out so although not very tall they look like they have a decent root base. Number 3 was planted directly into Coco after sprouting. Number 4 was a dryer pellet. I think directly into buffered Coco that's been flushed well is the way to go next time.

It will be interesting to see which two will be the final ones to get transplanted in the next stage of containers.

 

[Brett Blaze]

I forgot to add. #4 had roots coming out of the pellet after only two days so it went into a solo cup. So if you have the right saturation the pellets may work well. I just wish it didn't cost me 2 seeds to find out.

This folks is the difference between precision and me!

Damn Dano... I'm not sure I would be able to do all that. Maybe after kids are gone and things slow down in life, I'll give this a try. Have a great day.

I'm semi retired, kids have their own kids, so I have the time.

Stage - Seedling: Day 4

A little break in the temperature today. High will be 91° F (33°C) and the current Rh is 47%.

No water was added this morning since they still looked saturated and I am still concerned with drowning, even in Coco. Tonight/tomorrow I will most likely start a twice a day watering. All water includes the @Prescription Blend Core A and Core B nutrients at a ppm level of 150. When testing the PH last night it looked like it creeped low to 5.7. I needed to add some distilled water (PH 8.0) to bring the PH up which diluted the solution slightly.

The Demon LED light by @Budget LED has been set to half power which seems to be the right setting for now. During my last grow I had the light to low at the start and it did not have a way to adjust the power so my nodes were real tight. These look pretty good so far.

GSC #1and 2 have started to produce their second set of leaves. All looked pretty healthy but I think #2's growth may be stunted a bit.

PHOTO FLOOD WARNING!!

And one more.

 

[Lime]

#1 has got some vigor !
Coming along nicely

 

[Brett Blaze]

#1 has got some vigor !
Looking good

Yes but it's also 5 days older than 3 and 4. It has come back from the drowning and may do well. Still a lot of time left before I select the top two.

I'm semi retired, kids have their own kids, so I have the time.

That sounds like a wonderful and blessed place to be! One day, I hope that I can find myself in those shoes. Blessings to you and your family.

Your girls are looking fantastic! I agree with @Lime about #1, even if it is older. It certainly doesn't looked stressed out anymore.

 

[Brett Blaze]

Yes #1 is reaching towards the light which is a good sign. My bet is on #1 and #3 although #4 had roots coming out the bottom in 2 days. #3 was planted from sprout to the solo cup so no roots to compare to.

Stage - Seedling: Day 5

Temperatures today will get up to 96° F (36°C) with Rh 21% or lower.

The ladies are looking pretty good this morning. I gave each 20ml of nutrient water and got about the right amount of run off. Last night the run off was way to much so today I reduced the amount to 20ml and put 10ml at a time and real slowly.

It looks like #4 is catching up and is passing #3. Another difference for #3 (beside going right into the Coco) is it did not get any Great White because it was not transplanted. I also think #3 has a little yellowing possibly from too much water.

I took the dome off permanently today. I experimented last night and was able to keep Rh around 55% with temps near 75°F. The Ace Infinity T4 along with the humidity monitor and fogger are keeping Rh within 5 percent averaging 55%. The room, where the tent is located, is 72° F with 61% Rh using the A/C and humidifier. Exhaust from the tent is venting into the room which is not ideal but for now is the only choice. When the lights get bumped up to full this will change though.

 

[Brett Blaze]

Here's a view from the tent cam. When the humidity gets to 52% the fogger in the back left kicks on until it gets to 57%.

Stage - Seedling: Day 6

Hello Fellow Growers. Here's today's update.

Today's temps will get to 98°F (37°C) with Rh currently at 16% and dropping.

Tent Stats: Temp 76° F Rh 55%

All the ladies are doing well. I would like a little more stretch on #1 and #2 to allow for training so I reduced the light 25%. I had it at 140W which gave me 20K lux at 28". I just reduced it to 100W giving me 15K lux.

Actually I think #2 has been stunted so much it most likely won't make the cut but we'll see. #1 is still reaching for the lights and looks happy.

#4 has caught up to #3 which still has some yellowing. Not much but noticeable. I still think it's too much water. The leaves and especially the cotyledon leaves are drooping a little too compared to the others.

Here are the latest photos.

Happy Growing.

The down spike in temp is when the tent was opened.
