Propagation

I agree its a bit on the late side, but with warmth I think they will root. I think its always a race between Root and Rot - more light might help? so if it were me I would put give them some supplemental lighting, probably not until they have rooted / started to root, otherwise I think they may struggle over the winter. Depends if you have a Grow Lamp / Lighting Rig though ...

Thanks for the advice. I don't have a grow lamp/lighting rig, is it worth getting one? and are they expensive to run?

Lots of points to consider, on my list would be:

It provides something to do during the winter

Can keep plants alive that would otherwise die (particularly plants that were very small in the Autumn - late-taken cuttings would fall into that bracket, and also anything deliberately bought "cheap" because the nurseryman doesn't want to try to overwinter it)

Various types available - lighting rigs (tubes or LED) only suitable for putting within an inch or two of the leaves, so ideal for seedlings etc. all of uniform height, a Metal Halide growing lamp (and reflector) and other "Discharge Type Lamps" better suited to growing larger plants on as they will penetrate the foliage canopy

Running cost: assuming 17p per unit and running the lights for 12 hours a day from November through February is:

(100 watts / 1000) x (17p / 100) x 12 hours x 120 days

which works out at about £25 per 100 watts. A lighting rig that covers 0.5 sq.m. is likely to cost around £100 to buy, and be 200 - 400 Watts for 0.5 sq.m. You don't get a huge number of plants in 0.5 sq.m.

If you want to try a different Wattage / Electricity price / Duration calculation then you coudld put this into Google and vary the figures (the spaces are important)

(100 / 1000) x (17 / 100) x 12 x 120 =

Lots of very useful and well considered information to be found on the Cannabis growing forums - nothing like growing a high value crop to focus the mind on efficiency!

Kirsten, thanks for all the info but, as I'm one who gone 62, unemployed but not able to claim benefits before my pension kicks in, I won't be able to afford a grow light. Maybe I'd better write this year off and resign myself to buying new stock next year

I'd give them a go. A pot on the windowsill, covered with a plastic bag to keep the humidity constant, will probably be fine.

Or just stuff the existing plants into pots, straggly and scraggly and all!, and then take some cuttings from fresh growth in the Spring?

I'll try both of those ideas, thanks Kirsten. I've already potted up some of the 'mother' plants. I've cut them down a fair bit. They should be ok in the green house as I keep it frost free without too much heat. OH not keen on using window sills for cuttings/seed growing which is why I got the propagator - still he needs glasses so maybe I'll sneak the odd pot in and tell him they are pots of herbs for kitchen use!

I took some geranium cuttings at Christmas time last year and they did fine although seemed slow to root. If the mother plant is ok you should be fine as it sounds like you've done it before so know what you're doing.
