root rot can come anytime and theres realy no way to stop it
10" to 12" are MY tallest clones under a 600HPS...
You wanna do 6" at most... especially with the Sativa strains...
A 5" clone can produce up to 1 oz under a 600HPS...
Tall plants put the top and the bottom in different "light zones" (remember the drawing?)...
Short plants however, are able to reside entirely in the most intense light... you just gotta have more of them...![]()
I plan on lollipoping all the plants to take the light penetration into account. I lowered the lights another 3-4" and now the tallest ones are less than a foot away. We'll see how the plants react.
You are keeping your LEDs a foot away???
Wow... I keep my aircooled 600 HPS 6" above my plants...
I imagined LEDs would have to be really close to have any intensity.. guess I'm wrong...
