much water.

How lmuch time was devoted to soaking the seeds.....?

Then how long did you sprout them......

I prefer not to...but did you cover the seeds to increase sprouting....this can help to contribute to molding.


You want to keep the seeds moist the first 2 days....so they sprout evenly (if you have purchased good seeds.)

Then on the third day water them moderately.....keeping the soil or soiless grow mix damp...but NOT wet.

Where are you located(what state)...cooler or colder weather makes it easier to over water ...and have little or no problems..

But it sounds like you created a "rain forest" and that will almost always cause molding.

The fan for venatlation sounds like a good idea. I use 5 two horse power fans.(Breezemaker Fans Tampa Florida).

To my knowledge topical mold is not harmful....but subterainial mold can produce Salmonella and Ecoli....And when some seeds open they produce a Silica burst of a white substance that LOOKS like mold. No big deal.

By the fiith day if the trays are holding moisture....and I presume you are filling them to the top of 2 inches....so you get the maximine height. You should not have to water them the last two to three days....depending on heat and humidity....or cold and dry air.

Orchids like to be misted....wheatgrass likes to be bottom watered after it reaches a hieght of 5-6 inches.

The wetter you keep the seeds after they sprout ...the more you increase you chance of problems.

Remember you can grow wheatgrass in your bare hand...so KEEP IT SIMPLE!
