Jadeius i have taken your advise on the wall reflection, i have also descided that i am going to use rockwool cubes instead of buying soil cause to tell you the truth i cant afford nothin apart from the fertilizers now, (i am broke), is it true that all i need is like a grill peice or or some type of gauze stuff so i can let them drain, and if so how many times shall i water and fertilizer? cheers again
