If space is limited and probable costs are High where u live then sorting one out to perpetuate the strain, a solo cup would be ideal. Low feeds and low wattage lights will keep her alive and once space permits, upping it to a larger pot will give you an option to make a “mother” and I’ve cloned right in a Dw type system, air stone and time and she will pop roots, change the solution add the npk(low to start) and you have another plant going into veg/ and potentially flower. It’s not ideal but if the country and laws are what they are it’s a viable solution for a grower to keep product coming.
Light wise , any low wattage bulb, socket extension cord , daylight type bulb (bright white) will suffice. Just defoliate occasionally as they will grow , and defoliating slows it’s growth a bit and allows you the time you need to keep it going. I’ve kept plants in situ for over a yr. when I didn’t have space to throw more in. Matter of fact look at these , been in situ since June. Top em and defoliate about once a month or so. I’ve just hit it with sulfur to keep pm at bay and to acidify the media. Salts will build up, to counter that I use very very light feeds like one feed at a month , basically a cal mag at 1/8 the strength once a month and feed at 1/8 the strength twice a month. Water as they need it , sparingly, zero run off. They grow knarly with all kinds of shoots and once transition to a larger pot all those potentially will be a cola!
hope my input helps.
Tent size is 1x2x3’ small with a led light at 19watts. One usb fan that pulls 33 watts but it’s three speeds and at lowest it pulls 12watts, (desktop fan).
