Hello,

I am an outdoor grower and I love to grow everything. I was bitten by the bug of gardening about two months ago and have been learning how to grow since then. I spent a month trying to build my own grow tent to which I managed to get right, however, I went to a really nice hydroponic shop in my area to source a decent grow light and, in doing so, I fell for the sales pitch and left the store with a grow tent, grow lights and about 50 rockwool.

I am in the Southern Hemisphere and thought I would begin with perfecting the germination process in rockwool.

Rockwool is so easy and having an out-door growing background I sewed multiple seeds into my rockwool. It seems that almost every seed has germinated in the 6 rockwool that I sewed seeds in. The problem with this is that I sewed multiple seeds in to each rockwool. 3 rockwool has sprouted about 4-5 spinach stalks each and the other 3 rockwool has sprouted 4-5 onion stalks each. They look extremely uncomfortable and the onion stalks seem to be bending and twisting around each other. My thoughts are that either I should open the rockwool and attempt to move each plant in to it's own soil where it has a nice chance to grow before they start taking on the fibre of the rockwool, or to simply snip the weakest stalks until I have one stalk left and leave that to dominate.

Unfortunately my below-amateur knowledge of hydroponics (and possibly growing altogether) has put me in a position where I am not 100% certain as to what solution would be the best going forward, how do you think I can save these guys? Also, can you maybe assist me in explaining how many seeds I should be sewing per rock wool?

Unfortunately the average Joe that makes a Youtube tutorial doesn't present fact, but rather a methodology which can't be applied to other growing situations.

Thanks for assisting me and please feel free to correct any terminology that I misused and to give any advice, I would appreciate the hell out of it!

Kind Regards

Matthew
