Plant problems (Urgent)

one last question about light do you thing 250w metal halide is enough ? for 4 plants ?

250w MH bulbs i would only suggest growing 2 plants to get the best quality and quantity, but u can do 4 plants. but i would suggest 400w and u would get amazing grow with 4 plants

do you think i can use plastic (eps) foam instead of perlite in order to open more space in the soil for roots to get air and enough space to develop ?? if i mix plastic foam to soil?

Hey Guys i really need an answer for the last question about the foam soil mix...
please urgent help required

Not sure about the foam but why not just use perlite? It is sold pratically everywhere and isn't expensive.

your not feeding it wae anything are you ? dont give a seedling nutes and watch the water (not to much) make sure your p h is ok if its dry an inch below the suface water it with p h neutral water

im sure where ever you live you can find it easily but i've been looking for week for perlite here and i seriously couldn't find it. but i've been looking on the internet about the foam and i've seen several articles about mixing to and they say it wouldnt be problem, and already i've mix it. Technically it shouldn't be a problem, my only fear is when i put some put some extra element like potassium or calcium, it'd make a chemical mix and would leave toxic stuff but i will cross that bridge when i come to it... i've changed the soil it was awful sticky like a mud plus i've lost some root along the way. i am at this moment praying that it stays alive!! among them all JH is the most i expect to see grow... we will see..
