Please does anyone have a brain i can pick ?

why do you have to buy mh every 8 months ?

i have been told that you should re-place mh bulbs every 8-12 months why is this ?

i have a mh bulb running and i am running for the flowering stage i know that lots of people would change to a hps conversion but i have been told by a few people that sticking with the mh will give getter quality rather than quantity so i put an envirolite 125w (flowering bulb) in.

if i don't know how old my mh bulb is should i change it ?

pic below of my plants they have been in flowering for 7 days and 3 are female 1 i don't know yet

these plant have been grow from seed the mother was a hermie does that make these hermies or will they be female i can't see any balls just hairs ?

after a transplant do you use nutes i am growing in a cheap compost/perlite mix should i nute them they are due to be fed this feed?

thank to anyone who can answer one or all of the above

theres no pics

hahahahahahahaha your funny hahahahahaha

s**t how many time can i forget to post the pic this is like the 4 time in 4 weeks i think my brain is melting with all the info you need to grow

i will edit my first post to include pics now

HID bulbs can have less than 1/2 their initial output - and still appear blindingly bright. from what i understand, HID bulbs lose their lumens quickly over time. HPS should be changed every 24 months and MH every 12-18 months (from my understanding). If you are concerned, it is probably better to go ahead and just change the bulb. Or else get a light/lumens meter to be certain.

congratulations! the one on the right is a girl!

thanks EMAIL468 i don't know how old my light is so i will change it.

can anyone help with the other questions

as email stated, if you dont know how old the bulb is, might be a good idea to purchase a new one.. you will notice a difference in intensity between new and old.. (if you plan on having more than one grow, why not? you will need a new bulb eventually..)

just because the mother was a hermie doesn't mean you will grow hermie plants.. chances are they will turn out either male or female.. was your mother stressed into a hermie state or was it always a hermie?

not that big of a deal.. but i wouldnt be keeping plants with a history of hermies around very long.. inferior genetics (imo)

you will probably need to give those plants some nutes sometime in the next few weeks although they look healthy at the moment.. start off with a diluted feeding (1/4-1/2 strength) of some bloom/flower building nutes (high phosphorus content, lower Nitrogen and Potassium) and go from there.. no need to push the nutes though.. you'll just end burning them

will buy new bulb, all i know is the mother was hermie my plants 6 out of 6 are female upto yet i have read that they might show male later into flowering, got rid of 2 not got a lot of space in my tent, still going to get a smoke out of it this is my first grow so i will be happy with any thing, i transplanted my plants last night they look a bit droppy but that is probably just a bit of shock will not give them nutes for 4/5 waterings


thanks for the info chromer

Not just intensity, but the color temperature (Kelvin rating/spectrum) changes as well. This is also known in fluoro bulbs. It is a very important issue for people growing photosynthetic corals.
