lighting

[H11]

ok i have a mate that insists that for flowering the light should be 8 hours on and 16 hour off.

yet from everyone that i've spoken too and everything i'v read its suppost to be 12/12.

now were just arguing over whats right and wrong. can someone please confirm whats right and wrong.

 

cheers.

seriously man tell ya mate to go away i only heard of 8/16 as a last resort to cut out stretching during flower i would get ya light onto 12/12 ASAP

and if ya dont mind me asking what medium are you in and how much are you watering mate

 

hope this helps

15 mins every hour in clay pebbles. and havent cut roots at all. another thing were arguing over.

but i plant on cutting roots tomorrow as the leaves are drooping a bit,

[Stoney]

hey there again im in clay balls as well and 15min every hr is abit much in my books i have mine set to 15min every 2 hrs and also i trim my roots but only befor i go into flower but i always trim any roots that are hanging down into the tank below cause that where my water and nutes are so if this is the case trim any that are hanging in the water and yeah i would cut ya watering back mate

 

good luck with the rest these measures should help with ya leaf droop

 

cheerz

12/12.

If you use a decent size pot then trimming roots would be unnecessary, as for 16/8, tell your mate I said he has a shitload to learn about growing mj.

Light cycles like 8 on 16 off can be used to sex seedlings quickly when a new batch of seeds is grown out, but its not used in a normal grow as it will do nothing but grow smaller plants with a smaller yield (but with a quicker finishing time) The other situation its used is in the final stages of growing a strain that takes longer than usual to finish, say 12-14 weeks. Sometimes you need to reduce the light hours in the last 2-4 weeks back to 10 or even 8 hours to fully ripen the plant for harvest as some can adapt to the 12/12 lighting schedule and not finish off as well as they could.

 

thats probably where your mate has got confused.

 

The aim of the game is to give your plant as much light as possible but still giving it the minimum dark period to make it flower.

by clay pebbles you mean clay balls from the hydro shop I right?

 

I doubt cutting the roots will solve your drooping problem. Its more likely you got root rot with that watering schedule. watering for 15 minutes every 2-3 hours is more like what you should be aiming for IMO. Check your roots aren't turning brown or producing funny smells as these are signs of trouble.
