Smoke another ......in veg i have found it dont matter,
ive tried it all i just know 24hr light and,
any environmental stress will show characteristics.
so test your plant it wont hurt it its a weed...!
ive many times jammed a hid/400 24hrs a day and presently hid/600 24hrs
but just switch it it wont trigger to flower unless three environmental factors occur,
case study drive from Vegas to Colo with strain....

1 temp drop below 32deg
2 light cycle drop to 12/12
3 or complete darkness for 24hrs

its easy to trigger your plants to flower but in your case it should not make a difference in your very small box except HEAT......
Native¥organicfarmer Reviewed by Native¥organicfarmer on . Switch light cycles Hey I am going to switch my veg 18/6 cycle from off hours at 12:00am/6:00am to 3:00pm/9:00pm. What will be the best way to do the light cycle adjustments. Leave it on over 24 hours and then start? So on at 6:00am and not off again until 3:00pm the following day? It is a 400w MH bulb in a tiny 2x2x5 box. Rating: 5
