Hey! I need one of those! 😁
Soil blocker is a good investment and pretty fun. I was sitting out back with my kids and made 5 more sets of 4 in a couple minutes. I made a row the other day and just now had time to get back out there.
Time to get some herb seeds going and under the lights. Thanks for the recommendation nostr:nprofile1qqsx5q4h6h2urnhv859d9rwhr3x0a6ak89aetlh4e4gr9jfz8gfaq2sprdmhxue69uhkummnw3ex2mrp0yh8jet8dpex7tnnd96x2qg6waehxw309a6xsetxdaex2um59ehx7um5wgcjucm0d5q32amnwvaz7tmgd9ehgtnwdaehgu3wd3skueqg95d88

Yes. Yes you do. I got the 4 cell 2" blocks. Incredibly easy and fast. My kids have fun with it too. Been a great investment and I'm about to mass start seeds. nostr:nprofile1qqsx5q4h6h2urnhv859d9rwhr3x0a6ak89aetlh4e4gr9jfz8gfaq2sprdmhxue69uhkummnw3ex2mrp0yh8jet8dpex7tnnd96x2qg6waehxw309a6xsetxdaex2um59ehx7um5wgcjucm0d5q32amnwvaz7tmgd9ehgtnwdaehgu3wd3skueqg95d88 had good things to say for growth and limiting root bound issues.
I have done 2 seasons with mine, cant say enough, i find they grow 1 week faster indoors & a week faster once planted
