Trace the line back to the circuit breaker or fuse, it will have a rating in amps. Take 80% of that number as your maximum amps. Add all equipment amps together and it has to be below your 80% target. If you have the watts of an appliance but not the amps divide watts by 230 volts to get amps.

make sure your shop light is hps. No worries with brown hairs. You will get hundreds of seeds if you leave a male in with females.

You're limited by your horizontal space, 100 watts is about all you can fit.

What makes you think I'm not using a reflector? For pure physics measurements I went without a reflector but for growing, and with the chart, a reflector that emits light at a 120 degree angle was used.

still speechless

Note that the distances are from the bulb, not the hood. So you don't want a flat plant canopy, you want a stadium canopy.

No way to get there without larger dehumidifier

Not really. 3000 lumens per square foot as a minimum for flowering, 7000 lumens per square foot preferred

you want at least 50 actual watts of 6500k cfl's. you're probably going to need some nutes before flowering but you won't waste that much.

you can't get around venting - you'd need to vent the exhaust from the ac. If the temps in the room outside the closet are below 75 f then no need for ac, above 80 f and you have to have ac.

Your plant looks great, keep up the good work: 1. Hours of light don't really matter as long as you have light for at least 16 hours per day for this stage. 2. You will want to start watering only when the soil is dry down about an inch. This pushes the plant to expand its root system. 3. You...

You are going to need to vent air in and out of that space. Either use existing vents if they exist or cut holes in walls. You can always repair a hole when you move.

One tent with divider you put in - use black/white poly and zipper sold where you buy tent

The Way you are set up you are not making best use of your carbon filter and your ac vents smelly air, so you'd always need on a gel, whicqh is likely to be too little help when your plants are further along in flowering. Better to set up your carbon filter to recirculate room air which will...

Read the double your yield link below for both sides of the pruning argument.

lets see if this is easier to read: This chart shows how close you can get your plant to the light without it receiving too much light. It does not take into account heat.

Working on it

after examining the origins of the light distance chart i found a good bit of physics originally calculated by caligrower in 2004. i took his chart, verified the numbers for a 600 watt hps light, then updated it for newer bulbs and this is what you get: caligrower had light intensities for...

got a few other things going on right now that i need to figure out before refining formula, but basically what i did was take a one inch thick layer around the plant and added up the lumens each cubic inch would experience from indoor and outdoor light. the figures are going to change...

You are going to eventually want two chambers so that you can have more than one harvest every four months. Count on 12 square feet for your flowering area for 4 plants eventually, and a 600 watt hps light would be ideal. Plan on 6 square feet or less for a vegging area, with fluorescent...
