Thanks Hydro, What are you using as a soil? I've never seen that before (probably because I've only been here for 4 months, Not very new anymore but still inexperienced).
Straight perlite for everything. Here are a couple clones at 14 days when I potted up to a milk jug.
I make solo cup hempy style with one 1/4 hole 1/2 inch up from bottom of cup filled with straight perlite rinsed with tap water.
Poke hole in perlite for the stem to fit
I snip cutting at an angle then dip in root stim powder
Place into perlite hole made for stem
Pack perlite around stem
I follow nutrients for clones. I use another solo cup filled about 2/3 with nutriant solution. I place solo cup with fresh cutting into it to soak to the top so all perlite is wet, pull it out and let drain. ( I have used straight tap water with good results, leaves are just more yellow)
Place under light. (I use 2-20 watt t8)
Final result 14 days later.
