View Full Version : seedling starts

My seedlings get about an inch high and then die off. Too much or too little moisture? Light too close or far? They generally get their first set of true leaves, then those curl up and the plant folds over. Help !

What growing medium are they in?
Are they sitting in water/nutrient solution for any amount of time?
Do you have a humidity dome over the tray?
How often do you water?
Do you water with plain water or nutrient solution? What TDS/EC?
Are you using tap, well or reverse osmosis water?
What kind of lighting are you using and how high from the tops of the seedlings?

I'm going to be of no help other than I'm having the same problem. I started the plants from seed in rockwool cubes, used a dilute nutrient soln. The seedings grew tall and thin but then fell over and died. About 18 hrs of light per day, room temp 68F.

u either have too much nutrients, or ur light is too strong for ur little ones. try starting with no nutrients and add them after you have a decent root structure. ur light may also be a little intense for seedlings, try to have ur sprouts going and ready b4 u slam them with everything all at once.
