Day 22:
Drain EC 3 feet high and risin'😅( average 3.3 to be exact...)
dunno how much whatever-salt is building up in that pots, but it obviuosly doesn't bother the ladies.
Dark green colour, very few 'claws', no signs of tipp-burn, new foliage appears in a juicy green and turns dark in an instant, leafs point upwards.......
looks like they're happy😊.
Planns for this week:
- Install the scrog-net
- Obsereve plants/soil ( when do i have to feed nutrients again?)
otherwise there will be no changes......
Thoughts:
These bushy babies will be kind of a challlenge to create this scrog the way i'm used to (basically bending the 4 main main colas to the corners of the tent, upper branches to the walls and spaces between the pants, lower branches to the very center).
Now these ladies make so many branches, so close togehter and so equal in length, underneath huge fanleafs..... i'd love to have them in a 100 square meter canna-crib....but in a tent...????? I really hate doin' things without having them planned - but in this case i guess i will have to install the net, start weaving and see what's happening😯
Day 23
Let's keep it positive...... indoor-climate of 64% rh is perfect for my health💪😁!!! ......but in my tent it's killing the vpd😖.
at a lousy 24 degrees C, i'm readin' about 60-64 % rh wich results in about 0.7 to 0.8 kPa.*
More figures? Here come the crazyones👻!:
pH 5.5; EC 4.2😨
but thats only drain from plant 3....... average was 6.1/3.6
The girls busy produce roots, shoots and leafs....... still very green, still not unhealthy.......few claws, no tipp-burn.
Basically a comfortable place to be: It's not bad yet - no work but watering - and it can only get better!!!😁
*VPD issue solved:
The sensor hung too close to a fanleaf - didn‘t expect this thing beeing so sensitive 😅.
Day 24
Climbed new hights this morning: Plant 1 had an EC of 3.8 - the others didn't climb any higher than yesterday.
So maybe we've reached the climax..... 😇
Visible growth now - so i installed the scrog-net and will start bending and weaving these days:-)
Thoughts:
Did beeing out of VPD-range for one day harm my plants? How exact can my sensor measure VPD?
after a bit of research i found out: Whatever you buy for less than 200 bucks is far from beeing exact! Even professional sensors have a margin of about +/- 1% in relative humidity. Thermometers at least +/- 0.5 degrees C. This could give some a good guess of the actual VPD BUT: Leaf-temperature-offset is absolute key! Many of our trusted homegrow-equippment isn't even able to measure it (some offer default temp-offset) ....don't wanna go further here - but there's no way to achieve something like a precise VPD-measurement in homegrowing.
So why caring for VPD?
Even with those less accurate instruments, you may be able to keep your plants in something like a comfort-zone. Way better than only guessing 👆!!!
In case i ran a much higher VPD than planned, yesterday (due to a missplaced sensor) , it will not harm or kill my plants. they might have had a bit of stress from dry air - but nothing to worry about!
STAY TUNED 👈!
