Hi there, sorry for digging this thread, but I have some doubt in my home made media.
I had 5 different media prepared couple months ago, they are based on tomato juice and bananas, fertilizer, honey, table sugar, active carbon and agar or corn starch. 
1.st media was with banana and starch (and all other ingrediants w/o agar) and I omit to adjust PH - no germination after 50 days (1 jar)
2.nd media was with the same but with agar PH about 6.5 - no germination after 50 days (2 jars)
3.rd media was the same but PH about 5 - no germination after 50 days (2 jars) only something swell on the top of media
4.th media was with tomato w/o bananas and agar, I also add some multivitamin in it and PH about 5, I have one jar with protocorms and the second w/o
5.th media was with tomato and also bananas, brown sugar instead of table sugar and PH also about 5, I have one jar with protocorms and the second w/o
Seed pod was raw, 110 days after pollination seeds wasn't ripe, but it is as it is, I seed them.
My questions are:
1- 5.th media was faster then 4.th, but why only in one jar seeds was germinated and in second didn't?
2- which PH level is the best for phalaenopsis and which for dendrobium nobile?
3- do you have some tested home made media, by you?

Thanks a lot.
