Big time rush: minimum veg time for indica seedlings?

im germing 9 natural indys, and looking to harvest 10 g's per fem in soil, SOG under 400w MH. What is the minimum veg time (post sprouting) needed to roughly achieve this?

I wouldn't really depend on time, since this can differ from enviroments, what lights you are using, what nutes you are using and what strain you are growing. You would be best to start flowering when you have at least 5 nodes, ....

masterkushx5,mangox4(natural seeds) its a generic halide, the enviroment will be uncontrolled. how much stretching could i expect from 4'',3 nodes? keep in mind, ive had massive results with the mango outdoors. if these characteristics are compareable indoors, the results should be above average?

You want the plant around 12" that gives you 18" left for flower based on your 400, so your plant will finish some where around 25 to 30" that should give you twice what your looking for in weight. (15/20g)

Now there are a lot of variables here but it should be close.

3 & a half weeks for veg.

whats the smallest anyone has flowered an indy seedling?
