5 Seeds planted for each Strain
Northern Light
Black Domina
White Ice
(All bought from Sensi Seeds Store Amsterdam)
My equipment:
1,50 x 0,80 Growtent
2x Sanlight Q6W
Carbonactive Silent Tube
Growcontrol EC Pro
Taifun Humidity Controller
2x 40w Heating Mat
Was a good start, all seeds germinated, all plants look good
Day 1-8 : had some problems with RH but that should be solved now
Day 10-14 : some trouble with temperature, but seems solved too
Now after 11 days the roots show on the bottom of 1 of my 1L airpots, the plant is only 4-5cm high, so i assume the pot can't be fully rooted, but the roots already show on the bottom...
My question is: when should i repot into my final 12l airpot?
Ya they are healthy as can be that awesome how fast those roots traveled great man ...I would wait till they get that 3rd or 4th internode grown in and then transplant . By that point the roots will have developed all around the pot making her less likely to fall apart as you try transplanting them .looking like end of third week or closer to fourth just my opinion ..cheers
14.12 • Things look good
15.12 • raised temperature to 25.5° during daylight
16.12 • one of the Black Domina's leave has some light yellow spots...i wonder why..
19.12 • i think i'm missing some calcium/magnesium as i made the mistake and only used osmose water
20.12 • definately seeing some calcium deficit, repoting and adding some cal/mag aswell as some other stuff(biobizz alg a mag, emiko soil activator and alpha boost)
22.12 • Cal/mag deficit looks solved, plants look healthy
23.12 • last watering was 1L / Pot right after repoting on 20.12 , right now soil feels moist
25.12 • added a bio CO2 reactor (4x 1L bottles with 800ml water, some mashed tomato and 100g sugar, 10g moist yeast)
25.12 • rotated one of the lights to maximize illumination
26.12 • watered all plants with 1L
26.12 • CO2 ppm went up from +-400 to +-600 i hope for some more as i increased room temperature to 26°C, (yeast should react more due to increased temp.)
27.12 • sunburn as the lights were under 30cm distance
27.12 • CO2 wasn't working when i arrived this evening, perhaps i used too much yeast, perhaps it was too cold, perhapy i need bigger bottles...either way: i removed 3/4 from the bottles and refilled water/sugar/tomato
29.12 • it was planned to give the plants 8 days for germination & 21 days for vegetation, now it's the 29th day, tomorrow should be the 1st day of bloom but the biggest plant only has 25cm, most others only have 20cm....so i think i'll give them a few more days vegetation...
Perhaps the slow growth was because of the pure osmose water i gave them the first 2 weeks causing a cal/mag deficency
30.12 • had to cut the top of one of the plants as it was 5cm bigger then all others
1.1 • watered all plants with 1L
5.1 • last day of vegetation, most plants are about 30cm, the one i toped is 40cm
My plants are mostly indica and they're all +-30cm big now...
My room is 2m, so with lights and stuff on the ceiling and proper distance to the lights they may reach up to 90cm...
My question is: when should i switch to 12/12, so they reach their 90cm limit after stretch?
Hello there, looks like we're both growing NL and other indica dominant strains. So when to flip?
If you'd like to fully utilize the space and max out your plants as far as possible (upwards) I would not allow them to surpass 60cm in height. This will allow for roughly 60% stretch and leave you with the recommended 18-24 inch buffer space required for your lamp for appropriate core light spread.
In my experience, so far, my Indies don't surpass 50% stretch, BUT if you're concerned or feel they will stretch further (trust your gut, my friend) you can play it safe and flip at 45cm. This will give lots of buffer room and you won't have to worry about over stretching or light burn. (I'm also assuming your pot is about 30cm high as well and that has been taken into consideration for these measurements).
Just quickly and personally. I'm flipping at the 60cm-75cm mark because I feel it won't surpass the 50% stretch (with these specific girls). But that's my gut telling me that👍😉.
Hoped this helped my friend. If you choose this as the answer, there is no need to 'select' it. Of this is the info you needed, there's no strings attached. If you have more questions about flushing and nutrient schedule changes, pm me anytime.
Cheers my friend.
6.1. • watered all plants with 1L
6.1. • i wanted to put them in flowering phase but decided to give them a few more days, they're all about 30cm big(except 1 northern light, which is 45cm), if they stretch for 100% they'll be 60cm...my room can take 90cm plants...so let's give them a few more days...
8.1 • moved the lights again. The big one is at 50cm already...even after toping it when it was 35cm....all other plants slowly get bigger, average is 30cm now
9.1 • watered all plants with 1L
10.1 • height is average 33-35cm now
11.1 • lowered temperature to 23°
12.1 • moved bigger plants to the middle
12.1 • watered all plants with 1L
12.1 • WI #1=39cm #2=36cm #3=29cm #4=25cm #5=30cm
12.1 • NL #1=59cm #2=39cm #3=36cm #4=38cm #5=31cm
12.1 • BD #1=46cm #2=35cm #3=37cm #4=30cm #5=31cm
13.1 • planed switch to 12/12
13.1 • switched to 12/12, planed to harvest in about 55 days (08.03.)
14.1 • watered all plants with 1L
15.1 • it's cold outside, i'm having problems keeping temperature on a constant level during night
17.1 • watered all plants with 1L
19.1 • set up a watering pump as is can't reach the pots in the back anymore
20.1 • i see white hairs on almost all plants
20.1 • watered all plants with 1L
22.1 • average height is 50cm now
24.1 • watered all plants with 1L & defoiled some yellowing leaves from beneath to get better airflow
03.02 • all plants are in full flower mode, i think stretch is almost over, smell is getting stronger
04.02 • having big problems with RH... average 60+%....can't get it much below that
05.02 • watered all plants with 1L
06.02 • watered some more & cleaned the filter of the pump
10.02 • watered all plants with 0.8L
12.02 • watered all plants with 0.8L
14.02 • watered all plants with 1L
14.02 • i flushed the yellowing Black Domina with clear water with EC of 0.8 and checked the EC of the drain, it was 1.8...so i assume EC in the pot was like 2+, perhaps it was too high and nutrients had a lockout....PH was perfect (6.8)....perhaps the cause of yellowing was a lockout or N deficency...i have no clue...
16.02 • 3 of 5 White Ice are turning red/brownish...must be their genetics...
It seems i have 2 kind of defiencies
1 plant gets yellow on top
3 plants seem to get red/brown/yellow
I checked PH of the soil, looks good -> 6,8
I checked EC of the soil it's 1.8-2.0
I use bio nutriens from biocanna + some cal/mag -> my water has alot of calcium in it in my town
What you have here is a heavy feeder. She's crying out for pk so she's taking what she can from the leaves. I honestly believe if you feed this one plant more pk she will bounce back! Also I strongly recommend some defoliation. It's not a calmag issue, it's not nitrogen and it's not from your water source. They looked healthy 2 weeks ago so must be because of the flowers, no? 👍🌱
17.02 • watered all plants with 1L - added some Biocanna Vega
19.02 • harvested the early flowering NL, wet weight 138g
19.02 • watered all plants with 0.8L
21.02 • watered all plants with 0.8L
