Question: How large can you grow clones in an ez or aero cloner before you run into issues with the roots getting tangled? I am tight on veg. Space and would like to grow them to 12-18 inches tall if possible.[/QUOTE]
I have a 30 site, and have just upgraded a few months back to a 120 site and if you are using all of your space it wont be very long before the roots get tangled and drawn out, growing them 12-18" additionally would not be possible imo. I typically root Sour Bubble in 7 days and GDP in 10 (ready to transplant), I take the SB out and leave the GDP cuts in (but space them out as much as possible) to veg usually four or five sets of nodes and roots tend to be over 18" long and because my pheno of SB goes for 75 days I like the Gdp's to veg up for 10 days in the clone box and put them in later so I can take them all down at once. I would suggest taking bigger cuts also. I like mine to be 8-10" long.
