18/12 growroom set up

[fhydro]

Hello,
i want to set up a new grow room dedicated to 18/12, seedlings, cuttings and mother plants. I want to make it vertically. What is better ? How to split the grow room to manage seedlings and cuttings on one hand and mother plants on the other hand ? Thanks for advices.

personally i always stick to a 24 hour day 18/6 kinda thing.. splitting a grow room? put a wall in the middle...

18/12 = 30 hours total. With out demisions and a description (pictures would help too) I'm not sure what to advise. What type of grow are you planing, dirt, hydro what? are you experienced in construction or at least handy with power tools?

I'm sorry. Yes i'd like to know how to manage space to keep mother plants, seedlings and cuttings in the same grow room. And also how to select mother plants. Are they plants that you grow, put quickly to 12/12 to determine sex and put back to 18/6 to veg it? How to keep it without spending to much space ?
Thanks

First a mother is not required. If you donâ??t have the space then donâ??t worry about one. If you have a place to keep a mother then by all means do so. A mother plant is one that has growing traits that you are looking for. Either, short and bushy, tight nods, spacey branching, potency, good leaf foliage, ect.

I do not keep mothers myself, I just veg my clones until they are ready to move into the flower room. One week before they move into the flower room I take clones again. So these are clones x 14 now (meaning the 14 time I have cloned this strain from a clone)

Clones are given 24/7 of light (fluorescents is best because it will not heat up the leafs and dry them out) Aeroponics cloning is the best way to clone.

The problem is having them all in the same room is hard. Each will have different light requirements. Clones need the fluorescent light about 2-4 inches away and a cycle of 24/7. They will not be the same height, as your other plants so using the same light will not work for them. Clones can grow fine in a small cabinet with doors just watch the temperature and the rest of the environment.

You donâ??t need to sex the whole plant. There are several waysâ?? to determine sex. After about 45-60 dayâ??s of vegetation most strains will show their sex. The quick way is to take a clone as soon as you can, root the clone like normal then throwing it into 12/12 will show the sex in about a week or 2 at most.

Next you can place a bag over one of the mid side branch for 12 house of darkness even if it is during the 18/6 light cycle. This will also show sex and is better then putting the whole plant back into vegetation again.

I really like the alternatives given here to early12/12, reveg method...
clone asap, root, then 12/12, determine sex... or place bag over side branch 6 hours out of 18/6 cyle to sex ...that is quick & cool...
