Week 1 ended with photos on day 7, but that’s after planting seed - not after actual germination. Photos of this week start with day 7, probably skipping 1 day of slow growth.
Plant is looking good, no stretching, very stocky with a thick stem.
Day 7: 3,5 cm
Day 8: 3,9 cm
I switched from the IKEA 15w growlight at 28cm (supported by 150w UFO at 50cm - just for the heat at light cycle during cold nights, I’ll definitely look in to an actual heating solution)
to having only the 150W UFO at 32cm)
Temp at light cycle around 24C with 65% RH on avarage.
Since this is my first proper growth in a tent with a dwarf autoflower I’m still surprised how short and stocky this plant is. That’s why I lowered the UFO LED to 32cm from start of this week and keep an eye on problems. Might even lower it a little bit more.
Since the seed was in potting soil surrounded by Light Mix I started with a very light nutrients addition to the water on end of day 6 (when the plant had 2 sets of normal single finger leaves). A quarter of the recommended feed for Biobizz Grow for week 2:
Bio Grow 0,6ml / liter
Feeding 50ml water every other day for day 6, 8 and probably day 10.
From day 12 I might give more ml; weighing the pot after cycles to see when the water is gone.
Day 9: Too busy measuring pot weight and pondering whether or not to water. Pot weight was still increasing, I think it sucked up some water from the drip dish, or it’s incredible root growth, haha.
Morning day 9 (end of light cycle): 1310gr.
Evening day 9 (3hrs after dark cycle): 1359gr. I don’t think it can grow 49gr. of plant and root mass in 12 hours, or?
I stopped using the drip dish for humidity (i kept some water in there at a certain height so to pot’s feet would prevent it being sucked in to the pot).
Hung up a tea moist towel for humidity now, in addition to a mini usb humidifier.
Day 10: 4,2 cm
Day 11: 4,9 cm
Day 12: 5,5 cm ~ 6 cm
Day 13/14: 6-6,5 cm
I ended up slowly increasing the watering amount (day 12: 70ml, late day 13: 80ml and day 14: 100 ml.) in a way that the pot dried out in about 24-48 hours.
The soil on top was completely dry to a light color, and 1 to 2 cm in it was a darker color soil; ever so slightly moist I figure, but not leaving wetness behind on my finger.
Even up to day 14 the 100 ml. of water didn’t reach all the way to the bottom of this smallish 6,5 L pot. I one time sprayed the bottom with water (d 14) and later even let the bottom soak up a tiny amount just so the soil down below got slightly moist.
Of to week 3 of vegetation with my very first attempt at LST, as a bonus: performing it on a very short and thick-stemmed auto dwarf!
Don't worry they will fatten up it looks like they just need another couple weeks. Your feeding schedule is also super light compared to what biobizz recommends. They look good mate!
@indigold,
Thanks!
And yeah, my feeding schedule is super light, 1/2 or less of their recommendation. But then again, I've watered more often though in the first 4 weeks (almost daily) than the Biobizz schedule mentions (2-3x/week).
Can't remember when (somewhere in week 4-5), but the runoff was 1400 PPM, which I guess was almost 2 times higher than it should be.
And my plant is a dwarf - 39 cm / 1'3", doesn't that justify a lighter feeding?
