the sun grow compaired to a 400 hps

i have 14 clones in 2 gallon pots at 18 to 20 inches tall--they are just starting to hair on tips.would i see a bigger yeald with them budding inside under the 400 or outside in the sun-- growing in promix--with ph perfect 3 part fert with a few extras---bud candy-molasses rhino and a few more----what you think!!!

Outside would yield much more at the cost of more work. In 2 gallon pots outdoor you might end up watering twice a day

14 clones under 1 400w bulb??

The sun by a mile.

As long as the plant is hardened off and it actually gets a lot of direct sunlight, well honestly it wouldn't even be a contest.

plants have been in the sun for 1 month--roughly 24 inches tall---- they were 4 inchs when clones were cut.what size container would work better ?

The bigger the better
