I have started my AG's at a depth of 1/2" from the top of the seed coat. Now I am getting germination and my cots are still yellow when they emerge. Should my seeds be deeper or am I doing something wrong? I assume this is bad and I actually have put more VERY loose soil over the top of them to give an extra day of maturity before they are exposed to our very dry/hot air.

Please note that this is important as I am growing in AZ where these fragile cots are exposed to intense heat/sun except for my 70% shade cloth.

Yes, I think this should be in seed starting, but most people come here for question/answers.

Thank you,
Ben

Ben they will green up when they get sunlight. 70% shade cloth seems a little shady to me.

Linus,

As a former resident of AZ I can guarantee 70% is the least Ben can get away with ... and that is with misters. Ben - try putting a sheet of cardboard covered in foil about 12 inches above the plants so that they get a bit of morning and afternoon sun from the sides but don't get hit real hard for 2-3 days. I do that here in SoCal and we are only at 92-94 right now.

Hoppette, that is an excellent idea... I was really suprised with AG's how deep they should be planted compared to my germination testing Big Max's.

Linus, I didn't understand that they would green up easily in sun. My main concern has been the protection of these fragile cots. All my test plants that were grown in intense heat that came up early and yellow would burn under my glaring grow lights. I would test them at 100+ F surface temps so I saw the effects. Just a different way we have to look at growing unfortunately. I am jealous of you up there this time of the year.

Light = photosynthesis = production of chlorophyll = green leaves.

I don't understand your problem...is it the grow lights or the heat that is causing the leaves to burn?

Brigitte and Shannon need to get away from the northern lights, the diffused pleasant northern sunshine. Down south he sun is WAY more intense and add the temperatures and these leaves fry in the southern sun........

Here is my problem: My cots came up out of the moist earth in 102 F heat. Then today, we had an official high of 108 F. THATS HOT.

I was under the assumption that cots came up kinda green and when mine were yellow, I assumed something was wrong. I am pretty sure my little one in the garden has its tips fried because it was completely exposed for the whole day without help. I had seen this before in testers I germinated. The last 1/3 of the cot (away from stem) is whitish yellow in color the middle 1/3 is yellow and the final 1/3 is green. I think this little bugger will survive, but with damage. Now I wonder if it is worth saving.

I was looking for the input I got from Hoppette and currently I have implemented.

Hey Ben!

Did you soak them before planting in the ground? It sounds to me the 1/3 that is whitish yellow did not get as much water as it needs.
nothing you can do about that now, but if it keeps on growing it will easyaly grow out of it and put on better true leafs.

make sure you shade the vine tip, it will burn off on a very hot day.

when the seeds first pop out of the ground, you need to remember they were with out light this whole time so they will be yellow and just living on there protein(Untill they get light).

Best of luck Fellow Az grower!
