m0useanswered grow question 2 years ago It Still has the stretch to go through and it will gain some height from that.
I have been finding as long as autos have a stable root zone, not to hot, cold, root bound, bombarded with nutrients, nice PH they can get massive. but one thing goes out of wack and they dwarf a bit. My one plant went from 30 to 90cm after its stretch under 100w led from Spider Farmer. Had to bend its man cola a bit as it was to close to the light and I could not raise it any further. and in contrast my one plant outside got root bound by other plants in the same pot and they never made it over 30cm. Meanwhile the same seed in a solo pot got massive.
Keep at it and you will be golden.
Good Luck & Happy Growing!
