I've already given it a go
i bought 4kg of RCG, immersed in water for a day and put into shallow panes in my balcony(a day ago)
1-i had a wrong impression of area requirement: the seed size is about 2mm, with density of 1700seed/kg that would require 4m2 if we were to put in single seed layer, i had to put it into multiple panes stacked in 2-3 layers of seed(a pane or two are more dense,4kg is a huge amount)
2-i wanted some feed back how to provide nutrients in the liquid, i did some research and supplied about 3g Urea + 1g KSO4 + 0.5g MgSO4/ Litre ( i will provide P,Ca in coffee and egg powder later)
3-now a day is gone i'm having concerns of the water molding
4-i had another concern about birds(sparrows,pigeons around),as they could have got fat on my expense,phalaralis is bird seed

so far yesterday i think it passed safely
5-i should have processed seeds for foreign seeds,as i could notice it now,but hopefully will not be a big deal(if it worked at all)
