With the sativa I grow, 3 days veg after transplant works well. With the indica 10 days veg give a good plant. Had some pretty puny indica until I figured how slow they veg compared to sativa.
Growing the same plant until tuned in on what is genetic and what is controllable gives the grower an edge when growing something new later. A new strain every grow gives random feedback.
The following is from test grow, my only vice is buying every light I can afford and putting it in the test room just to see. An example of how specific advice can backfire.
To nearly eliminate stretch in my sativa I use a 400 watt coral HID with a 450 nanometer output (sky blue). With this light supplementing (not replacing) the veg lighting, the sativa can veg for 10 days with very similar results as an indica under standard veg lights. Stronger stems, less fall over later.
When I received my first indica the clones were put to veg with the sativa. I let things slide for a week before noticing the complete lack of serrated leaves.
Inspection revealed all the leaves were singles with smooth edges and every single one of them grew from the first 1/2" of stem. The plants were 6" high, branches and fan leaves (singles, actually) parallel to the stem.
Took out the blue light and a week later new leaves started showing with serrations and new nodes were separate. I lost 2 weeks and the plants were stunted their entire life span, yukky yield.
All that negative from the extra blue the sativa's thrived under better than any other supplement tested so far. Until it tried to kill my indica it had my endorsement for all vegging. That would have garnered some "disagree" from indica growers for sure.
