I wouldn't personally flip a 5ft og, it would end up an 8ft+ floppy nightmare of lesser quality than it could be IME. og's produce the best quality when flowered at 12-18", they stretch 2.5-3ft no matter how big they are at flip. I get my best results flipping og's @ around 18" tall, with at least a few tops, 9 like that will easily fill up a light. those ladies usually end up right around 3oz from a 3gal pot(og's tend to prefer a bit smaller pots ime, I use 2 & 3 gal exclusively, 3's in summer, 2's in winter)
I NEVER foliar feed!
Menards and Home Depot are out of seed starter mats so I ordered some and hope it helps. Everything else rooted no problem, a little late maybe, but the sfv cuts I took aren't doing shit after 25ish days in the dome
do the cuts you're taking have nice green, pliable/soft stems? the woody, sometimes striped stems are tougher to root. rapid rooters, dip n grow, and no dome and og's are usually rooted in 12-14 days or so for me. I use a mat in the winter but not so much now that it's warming up.
Forum cut? Looks beautiful
The cuts were all new lowers that were still nice and green, I guess a couple might have had purple stems, but the heating pad and domes are a must for me because my rooms are all built in my basement, temps stay between 72/68 in my veg room, with ambient RH between 40-50% pretty consistently
