Can a simple household lamp prevent flowering?

Yes it can work, even a full moon has enough light to prevent flowering. However, keeping a plant going all through fall, winter and into spring/summer is a big, big ask. I would suggest starting just after the mid winter equinox, around the 21st June or December 21st, depending on which hemisphere you are in, as they will still grow very large, but with the reduced risk of problems and with survivability tremendously enhanced. While the idea of big plants may seem enticing, which is something I wanted too when I started growing over 35 years ago, it does involve some issues. Firstly, room/space, unless you have acreage, this can be hard to manage. Secondly, you end up with A LOT of small crappy buds from the inner section of the plant and it is really only the ends of the branches that are getting most of the light that produce the decent flowers. Thirdly, a extended veg time can lead to plants building up an "anti-flowering" hormone in their system, so that when it does come to flowering time, they can be really stubborn to initiate the flowering phase and because of this, don't finish flowering until nearly winter time and with all of that seasons' associated problems. Fourthly, if you need to keep them out of sight, this becomes nearly impossible. Fifthly, and this is what really put me off growing big plants, you end up with a huge pile of the same stuff, which gets pretty boring to smoke month after month after month (especially if you don't like it that much!). These days I plant very late in the outdoor season (a month before the summer solstice) and grow many smaller plants, this way you get to try a lot of different strains, they are easier to look after, the soil will last the entire grow, the plants are keen to flower and do so without hesitation, the entire plant has decent flowers from stem to branch tip due to no excessive shading, (meaning no "pop corn" buds), and the best thing, a differt type of smoke for every occasion! While it may look impressive on youtube, the reality of big plants is there will be a lot of un-useable crap from the middle of the plant and unless you want to make extracts, all that small crap is a big pain. And a big waste. The only way to avoid it is to "manifold" your plants and then tie down every single branch horizontally and unless you have acreage, this becomes impractical. Believe me, lots of smaller plants is better than one or two huge plants, I just wish I worked that out 35 years ago! Hope this helps, Organoman.
