sorry just over 400 in nutes my bad, the point im trying to get across is you are spending money on stuff that in the end won't be the difference makers in yeild or quality. The additives can be argued in an absolute perfect growing enviorment could boost plant growth, but we haven't even got 1 crop yet. the guardian, could of spent 100 bucks on pen which in the end would do the same thing. ( I would love to have a guardian, but is isn't necvessary) they aren't gonna fix lack of light issues in ya plants.
Trust me mate we all want you to succeed in this adventure, although we are coming across as stand offish we are all trying to help you. I think everyone who has posted in this thread has harvested multiple crops in doors, gazza has done aero plants, arguably much harder than RDWC, he knows his shit.
