My question is, do these seedlings look healthy?
Is the growth of the 2 smaller sized seedlings normal?
I noticed the 3rd seedling growing at a much faster pace compared to those 2.
Could this possibly be a sign of stunted growth from overwatering?
Temp is kept around 73-85. RH around 80%
Any help would be appreciated thanks!
Welcome to the forum.
Don’t expect the seedlings to look like twins. They are cousins at best.
Correct
I would get rid of the straw in the cups. You don’t want to encourage soil moisture retention for a cannabis plant. Seedlings hate wet soil. All they have is a tap root and it is easy to overwhelm a seedling with too much water. Roots need oxygen and it is very difficult for a seedling to extract oxygen from the soil if the soil is wet all the time.
The best method for seeing that a seedling has what it needs without risking root rot is to instead use a dome and to not water the soil at all. Use a clear Solo cup or a cut pop bottle and spray inside of the dome a couple of times each day. The plant can get all of the water it needs via the leaves from the humidity in the dome. Start watering a few ml a day when the plant outgrows the dome.
Thanks for the feedback! I also want to mention. I followed the 10% watering rule and forgot to cut drainage holes in the cup until 7/16. Whoops
What is the 10% watering rule?
10% volume of the 16 oz red solo cup
Not really a good practice. Seedlings only need a couple of ml of water per day at the very most. Overly wet soil will kill or stunt the growth a cannabis seedling. As suggested above, it’s best to not water the soil at all and instead use a dome.
Thanks! Definitely going to give that a try. I plan on planting 3 more seeds directly into soil and using a dome this time. The plan is to have 4 final plants. Do you think they’ll catch up in time?
Back off the watering and do the best you can. They should be fine.
