Week 3 has shown a lot of progress. 1 of each strain has grown very large very quickly and they look to be ready for LST soon. Temperature conditions have improved in the last few days with a few changes to my grow tent. One major change is I had to replace my RDWC system for a DWC system due to sudden serious leaks springing up. Roots have started growing into the nutrient solution.
OG Kush #1 is looking fantastic. Has grown its first set of 5 finger leaves and should be ready for LST soon.
OG Kush #2 is growing a little slower than #1 and is showing some wilting on some of the leaves with a dark purplish color. I trimmed some of the worst spots. PH looks good at 6 for the water with about a 200 PPM solution.
Misty Kush #1 has overtaken OG Kush #1 as the largest plant. 1 leaf has a small amount of brown on it but otherwise its looking great and growing quickly.
Misty Kush #2 is the smallest of the bunch but has shown some increased growth rate over the last couple of days. I was not expecting this one to make it as it was bent completely over due to too much stretching during its first week. Its stalk is now strong and straight and looks very good.
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.
