I seem to kill seedlings in my tent no matter what environment/light/pH/humidity/temps I give them. I've spent a lot of hours reading and changed a lot of variables to no success really. I have grown one plant from seed to harvest in the tent in my waterfarm but all other attempts have been failures. I'm trying soil this time but my first plant to pop is now starting to slow down. I'd like to save these ones this time.
I'll try to describe what happens to the seedlings: They always seem to germinate well, I take care when germinating and have 100% success rate so far with every seed I've wanted to germ. The seedling straightens out, the cotyledons pop open and everything is great. Then after 2-3 days the growth all but stops and the plant stops progressing. It looks green and healthy to me, but it just won't grow. It looks like pic 1 below. The tiny baby leaves really never get much bigger than that and height is stunted. Back in the day we used to just take bagseed and put it in shitty walmart soil, shitty lighting, and use shitty un-pHed well water and the things would grow like hell. So it irritates me that I've spent all the time and money on this setup just to kill them. My seed stock is not the greatest but I do have seeds from a reputable online seller and tons of decent bagseed.
Here's some of the things I've thought were the problem and made efforts to change without much success: too much light/low humidity/damping off/bad seeds/germination methods....
Below is my current set up but I've tried it a lot of different ways.
Your Equipment:
1: Type and wattage of lights. 400W CMH
2: Distance from tops? 3-4 feet
3: Reflector type? Open air reflector
4: Is there a consistent fresh air supply? Passive air intake flap, circulation fans by intake, doors to tent open most the day
5: Do you have an exhaust fan and a circulation fan? Exhaust Fan: 4" 170 CFM, circulation fan
6: What are the bulb wattages, kelvin ratings, and schedule? 400W CMH 24/0
Your medium:
7: Specific brand and type of soil? Seed Starter Soil, (Burpee) and anything you've added to it. No additives to the seed starter soil.
8: Size of container? 16 oz. Red Solo Cup
9: Did you use peat pucks (or similar) to root clones or germinate seedlings? No
Your nutrients and water:
10: Source of water? (tap, bottled or filtered) What's it's ph before adjusting? Bottled distilled. pH: 6.5 right out of the bottle
11: Method of checking water ph? Hanna pH/EC/PPM test meter
12: Method of adjusting water ph? No adjustments
13: Specific brand and N-P-K ratio for each bottle. List dosages (quantity per gallon) and current feeding schedule. NO NUTES
14: How often are you watering between feedings, and how much per watering? I've been watering every day about 1-2 ounces per cup until top soil is uniform moistness
15: Any additives or tea's? (Superthrive, CalMag, molasses, Mother's Earth...) No
16: Are your ph levels stable, or do they fluctuate? Water is stable, have not checked runoff as there is hardly ever any runoff, soil is moist top and bottom
17: What is your ingoing water's ph? ...your runoff ph? Ingoing water ph 6.5 0 PPM
18: Do you foliar feed? If so, with what, how often, and at what time do you spray? No
Your growroom:
19: Indoors or outdoors? Indoor
20: What size of closet, room or hut? Mylar Lined Grow Tent 22"W X 36"L X 63"H
21: What are the temps and humidity levels while lights are on? 75F, 20% humidity ... With lights off? 24/0 light schedule currently
22: Have you seen signs of insects in the growroom? No
Your strain:
23: What strain are you growing? (Indica dominate or Sativa dom?) Aurora Indica, PPP, bagseed backups
24: From seeds or clones? Seed
25: Is this an autoflower strain? No
Pic 1 is Aurora Indica taken about 24 hours ago, Pic 2 is most recent AI pic. Pic 3 is PPP about day 4 and Pic 4 is bagseed day 2 or 3. Thanks in advance
