well if ya want to grow lowryders outside ya will have to wait till about end of may to plant out or even june
cause the long term weather forecast is bad that the ground wont be warm enough for the lowryders.
if ya do it before then wont get such good returns, they grow better in warm ground
but if going to grow out side need to go prepare the ground now
if ya get ur ass to aldi you can pick up a ph meter and stuff dead cheap
test the soil after the nutes, compost have been in for a few weeks
then u can adjust the ph with lime and stuff,to let it wash in
cant do it at the same time cause can get a chemical reaction that can be bad for you and soil round you
but still have to start them off in doors, but why dont you grow some other types like early girl and hollands hoop/hope(depends on the seed supplier which name it is) hollands hope/hoop can give up to 11oz form my own grows wild but depens on the weather
because we get long days here for so long, the plant doesnt start to flower late in the year. then we have windy weather which the plants dont like and can cause some to stress out and produce male pollen sacks( sort of a survial mode)
i would go with the early girl as it is an autoflower and pretty forgiving for a newbie grow
as for going back everyday only do it if no one will ever see you
but better of just letting it get on with it
and dont really need nutes if ya start with good soil and if growing in a pot with the lowryders use one to start them indoors then use to harden them by taking them out 1st. then ya can transplant them as they dont like change it stunts their growth.
this may sound mad but if want to grow in ireland outside and wild best not planting non auto flowering untill late may early june they will be smaller but would be able to harvest mid oct early september
between then ya can be growing the lowryders
any more info just ask
hope helps
