Hi,
I have 3 seedlings that aren't doing very well. Can I get some guidance?
What I used/did:
- 5 phototropic Northern Lights seeds
- I germinated the seeds in paper towels, they sprouted fast. 2 days showed over 10mm cotyldons. 4/5 seeds made it through germination.
- I planted them in peat pots with pebbles at the bottom using FoxFarm Light Warrior seed starter soil
- All four of them sprouted up nice after just a few days
- Then I noticed that if I didn't water them kind of heavily they would fall over and come close to dying kind of quick, so I proceeded with moderately heavy watering.
- I used natural sunlight for a day or two while I waited for my tent and light to arrive
- About 3 days into being seedlings I placed them in a Vivosun 2'x2' tent with a VS1000 LED Grow Light up top about 30" away with the dimmer on 25% power
- They've been getting about 14 hours of LED lighting per day
- The light looks like it's mostly daylight (very white light) with some red LEDs. Not sure if this is the correct LED color combo to use, or how to change the colors if needed
- The fourth seedling has pretty much died, the rest look medium / bad with regards to health
Thoughts from more experienced growers?
