As a first time grower* I have been monitoring the progress of both strains over the first week. Both strains seem to be growing similarly in height but OG Kush has much faster leaf development. Spray every 2 or 3 days with a 300 ppm solution.
2 x OG Kush (1 seedling is 3 days younger due to a seed not popping the first try)
2 x Misty Kush
OG Kush seems to grow at a much faster rate compared to the Misty. The first serrated leaves have already grown larger than the cotyledon leaves and have started growing above them. Both plants appears to be strong and healthy.
Misty Kush has had some Issues with stuck seed casings and a small propagator has led to some weird bending on the Misty strains. Unsure if the slower seedling growth is normal compared to autoflowers or if it is an issue with their environment. The cotyledon leaves seem to droop considerably and the serrated leaves are developing quite slow, still being maybe 1/4 in size to the cotyledons.
At the end of the first week I have moved the seedlings from their tiny propagator to a larger tray under my grow light about 36 inches from the light. Expect to move to their final RDWC home by the end of next week.
Setup:
4x4x6.5 Grow Tent
Kind LED L600
General Hydroponics Flora Trio
CaliMag
Hydroguard
DIY RDWC System
*Not counting attempts made in younger days with little growing information and poor grow conditions.
Looking better In week 2 with the supports. that seedling stretch in week one though dam. Was the light too far off ? Or maybe too hot ? I swear by t-5’s no heat and you can put it an inch away for first 2 weeks.
@Blackadder, Right now im seeing low 90s in the tent during the day and mid to low 80s at night. They all seem to be growing fairly quickly now, they are noticeably bigger now than when I went to work this morning. Ive moved them into the RDWC buckets.
@RogueLycan,
I’d agree with that, looked like they were reaching for more light. The dome may have reflected the light too combined with the distance/watts.
I’m not so sure on heat my current seedlings grew in 83f to 90f but with good lighting right from the get go. They grew slightly slower but height wise pretty short. I just use cling film over pot until they sprout then get um straight under good light. I think too much heat stops growth as the stomata close and you notice water droplets on leaf surface as there trying too cool down rather then stretch. I’d recom next time for go the dome, Ambient humidity usually ok and get some low watt cfl/t5 nice and close. I’ve been starting mine in 5 gal pots lately :O
What sort of temps you facing ? Anything under 90f isn’t too bad just not optimal
@Blackadder, Hard to say since I was using all new equipment and havent tried to grow since back in my younger days in a closet with no knowledge lol. If I had to guess Id say I left them under the humidity dome too long with bad light placement (just sat a small LED on top of the dome). Can too much heat cause that stretch? Thats actually one of the issues im having with my grow room at the moment, although I plan on fixing that with a dedicated ac unit till fall hits.
The LED I was using was from the small propagator I got from Nirvana so not sure how good it is.
@Tonino, Checked on OG Kush#1 this morning and it really stretched out a lot last night. Didnt have time to grab a picture but it looks like it jumped up at least a couple inches.
