actually not. it's the hours of darkness that matter, a minimum of 12 hours continuously. there was a sample grow here, unfortunately in the growfaq, that used a flowering schedule greater than 24 hours with 12 hours of darkness and increased their yield quite a bit.
here's a chart to help you feel better about your luck:

you need to understand the difference between radiant heat and ambient temperature. radiant heat passes through the air and directly heats an object - as an extreme radiant heat is what cooks an egg on the sidewalk on a hot day in the desert. the ambient temp of the air is in the 30c range but...
the only good reason to cut fan leaves is if you want to slow the growth of that part of the plant relative to others. for instance, i've cut alternating fan leaves off of the main stem to help the secondary branches catch up and create a full canopy with multiple colas (also topped the main...
ok, here's the deal on temperature. the guidelines for room temp are for a thermometer at the top of the plant canopy but shaded from direct light. if you don't shade it the thermometer will read ambient air temp and radiant heat combined. you test for radiant heat by using your hand as a...
you can rig anything that has a clear top and completely encloses the plant except for very small air inlets. you might be able to cut out the bottom and top of a cardboard box and use plastic wrap over the top. the plastic also helps cut out some light to protect your clones.
unless it is very humid where you live you need to find something to increase the relative humidity of the plant's environment. no reason the same humidity dome used indoors wouldn't work for you outside.
two 85 watt actual bulbs gives you about 10,000 lumens which is good if you end up with one plant and is acceptable but weak if you end up with two females. always - as much light as you can afford, fit and cool is what you want to achieve. increasing light is the cheapest and easiest way to...
go ahead and start flowering anytime you want. nothing in your pic that shows scale and i have no idea how much light you're using so it's kinda hard to even guess yield. but your plants look really healthy and if you just continue to give them the same level of attention it's reasonable to...
side lights can be very useful when the plant becomes too big for fluorescent light to penetrate below the top canopy, but they don't really help much at this stage. oh, and it helps to have a small oscillating fan blowing gently on your plants to make the stems even stronger and to keep fresh...
your babies are stretching pretty badly from too little/too far away lighting. if you're using fluorescents you should keep them within a couple of inches of the top of the plant. as they are, your babies may not have strong enough stems to support a decent plant. you should add more dirt to...
rock, meet hard place. if you plan on a larger space with more light in the near future it wouldn't hurt to buy the lights early and see what you can get away with in your current situation.
100 actual watts or equivalent watts? for instance, a 26 watt actual cfl is a 100 watt equivalent bulb. you're already in a little bit of a tough spot because it looks stativa dominant and is pretty large to use cfl's on. if your bulbs are 26 watt actuals you should get at least two more for a...
guess i'd have to say you're a great grower who could do even better with more efficient lights. you could get 380,000 lumens from four six hundred watt lights, 2400 total watts, compared to your 240,000 lumens and 2600 watts. it really wouldn't be a contest.
bigger is definitely better for many reasons, so if you can do that, go ahead. if you get stuck and need to consider my idea, you can always place your plants on increasing smaller boxes (or anything convenient) as they grow.
yes, but you'll get a lot better yield if you add some more cfl's along the side of the plant near budding sites. you should be keeping the cfl's within a couple of inches of the plant to maximize the amount of light hitting the plant.
1. the easiest way to increase yield per watt is to limit the size of your grow area in such a way as to achieve 7,000 - 10,000 lumens per square inch. you've got about 145,000 lumens to work with so that means a flowering area of 15 to 20 square feet. yes, i know this sounds small for a 1000...
