a little white mold on starter plugs

by Jan
(VA)

This is a true newbie's question. I've just started my very first seeds in the starter plugs. I've noticed that a thin layer of what looks like white mold is growing on the starter plugs in the part above the nutrient solution.

Does this mean that I should've already put the plugs into the clay balls and main growing system? The seedlings are up, but it doesn't seem like the roots would be very well developed yet.

Do I need to toss this batch and start over?
----------------------------------------------------------

Answer from Stella/Simon:
To be honest, I think I would start over. It sounds like the starter plugs were left too wet and grew some mold, which can be devastating to a garden. Seedlings should be allowed to dry out a little, and provide good cirulation, like a small fan. Make sure to sterilize the starter nursery pan with bleach before you start over.

thanks and another question
by: Jan

Thanks, this is very helpful. I had restarted a new set of seedlings. However, I was under the impression that the plugs were to just sit in water until they were transplanted.

I reviewed the pages you mentioned and made special not of the damping off section. Can I ask how this works with a lettuce raft. I followed your instructions for the homemade version. Aren't the newly transplanted seedlings basically sitting in water?

Answer from Stella,
Yes, you are right, they are just sitting in water, but there are two differences:
In the seedling flat, it is normally warmer than your open-air garden (lettuce raft). The seedlings are kept warm and well lit to help promote germination. This also makes it a possible hotbed for mold or algae to grow. That's why we advise letting the plugs dry out just a little bit.

Once they are in the raft, the nutrients are well aerated with an airstone, this aeration goes a long way towards preventing disease. Also the raft should have a fan blowing very gently towards the garden, which also prevents mold.

Make sense? Hope this helps.
Stella
