Shelf gardening cannabis with fluorescents could be the trend of the future, since the supplies are so affordable, and straightforward to obtain. Fluorescent lamps are excellent for shelf gardening. In this program, a lot of shelves may be placed, one above the other, and fluorescent lamps are utilized on every single shelf. Some shelves have 24 hour lighting, some have 12 hour lighting (for flowering). Two places are greatest, maybe with 1 other devoted to cloning and germination of seed.
Shelf gardening assumes your going to keep all plants 3′ or shorter at maturity, so all shelves are 3-4 feet apart. Less light is needed once you have plants which are this short and forced to mature early.

One drawback to a cannabis shelf garden like this is that it really is extremely time consuming to adjust the lamp height every single day, and it is harder to take a vacation for even a week with no tending of the garden. This applies mostly to the vegetative stage, when plants are growing as significantly as an inch per day. Lamps on the flowering shelves are not adjusted almost as often.
Typically, the lamps need to be kept within two inches of the tops of the plants, using the plants arranged such that they get progressively taller as the finish of the lamps go up, to ensure that all plants are within this 2″ range. This is an ideal nevertheless, and in case you do go on vacation, adjust the lamps to ensure that your positive the plants won’t be able to grow as much as the lamps within that length of time. If enough fluorescent are utilized to entirely saturate the shelf with light, the spacing issue will not produce spindly plants. They are going to merely grow a bit slower if the lamps are not extremely close to them.
An option would be to use fluorescent lamps for cloning; germination and early seedling growth on the top shelf of a closet, then switch over to HPS for heavy vegetative growth and/or flowering in the primary closet location.
Position the HPS such that it won’t require adjustment, at the leading most feasible point within the closet or room. Most HPS installations won’t require lamp height adjustment. Just attach the lamp to the underside of shelf or ceiling as high as feasible, and if you want to get several plants closer to it, put them on a temporary shelf, box or table to obtain them closer towards the lamp.
A shelf is all which is needed with this kind of setup, preferably at the very least 18″ wide, as much as about 24″ maximum. This location must be painted a extremely bright white, or covered with aluminum foil, dull side out to reflect light back to the plants. (Dull side out prevents hot-spots; diffuses light better.) Paint the shelf white too. Or, use aluminized Mylar, a space blanket, or any silvery surface material. Do not use mirrors, as the glass soaks up light.
Hang shop lamps from chains and be sure you are able to adjust them with hooks or some other kind of mechanism so they are able to be kept as close to the plants as possible at all times (1-2″).If the lamps are too far from the plants, the plants could grow lengthy, spindly stems trying to reach the lamp, and won’t create as considerably bud at maturity. This is due to internode length getting a lot longer. This may be the length of stem among each and every set of leaves. If it truly is shorter, there may be far more internodes, thus a lot more branches, therefore a plant that supplies far more buds in less space at harvest time.
Shelf gardening is at times referred to as Sea of Green, since many plants are grown close together, creating a green canopy of tops that are grown and matured quickly, and the next crop is began and growing concurrently in a separate area of continuous light. Clones are raised in a constant light shelf, until they start off to grow nicely vegetative, and then placed on a 12 hour per day shelf to flower.
