I built a sealed room inside my garage. It is ALOT OF WORK but really not too complicated. I used 1/2" ply wood on the outside walls, 8' 2x4's in between to hold it all together, and 1/2" sheet rock on the inside of my room. I used regular wall insulation between the ply and the sheet rock, and...

I don't think humid air is going to hurt your bulb, at least while it is on. most light bulbs generate enough heat so water cannot condense on it, however, if you are pulling cool/humid air through your system you may want to watch for condensation on ducting and reflectors. If the bulb is...

I have my inline fans hooked up near my intake dampers and they push air through the reflectors and out. I run a sealed room with CO2 and sealed intake/exhaust for my lights. Reasons: 1. It warms the air slightly before entering my reflectors and causes less condensation, especially during...

Yes I agree understanding the grounding is probably the hardest part. I had to read several times just to know how to do it, and then researched for an hour or so to understand why I had to do it that way. If its a remote building you will also need to install lightning protection.

I am not an electrician but I will tell you that this is not true. You get what you pay for. [email protected] = 110V@3A and it all costs the same. Based on that, and all of the equipment you described you can probably get away with using a 60A panel. I would wire 220V to the panel using 6/3 wire and...

I would run a 6/3 wire, install a 60 amp sub panel, and then wire both 240V and 120V plugs for devices. If you are not using the full 50 amps on your timer you should be able to power anything else you need as well. Plus it's safe.

With a little research you should be able to figure out how to install a sub panel. It is really not too difficult. I am not an electrician and I was able to wire power to a remote garage with conduit, #2 wire for a 100amp panel, buried x2 feed deep to code, the works. There are many internet...

I used to have a 4' x 10' "box" with 2 600W lights mounted in a static position to the top of the box 3 feet above the base of the plants. Inside I had 4 rows of 10 plants, and each row was a 2 week cycle. I would simply take out one row every 2 weeks, harvest 10 plants, and put the row back...

I have a sealed room and had serious condensation problems too. There may be better solutions, but what I did here seems to have fixed my problem. I fixed it by having a passive intake in attic (cold outside air) and "attic exhaust" believe it or not straight down under the house. This keeps...

How much light you need depends on how many plants you have and how much vegging you want to do. I don't use T5 fluorescent lighting so I cannot even begin to give you exact wattage per plant vs size, etc. Any indoor garden shop is going to have the lights you need, as well as simply just...

400W MH burns HOTHOTHOT especially without being air cooled. If you were to get a hood or cooltube you would probably be able to cool it enough to use it in your situation. Anything less is going to be extremely challenging, if not impossible. If it's just for vegging until a they are a foot...

I would imagine it would. I had a 400W MH system and I upgraded the ballist and bulb to 600W HPS and am using the same reflector. The bulb was totally different in both shape and size but it fit into the same socket in the reflector.

An old phone charger might do it.

The best I have seen (live) is 1lb+2oz with a 600W and that was considered excellent. Reports from here show better can be done. 2lb might be possible, but I would not expect 2lbs on your first grow with a new setup. It will definately take some trial and error and fine tuning your system to get...

I would say with almost any method you choose as long as you don't make any huge mistakes and everything goes a little better than average you should be able to harvest an average of 3lb with 1800 watts of light. Some can do better, most do worse. Please don't take that estimate as a guideline...

First you will need SPDT thermostat, one that will power one item when its warm and another when it is cold. Sometimes Lowes/Home depot/wally will have them, they are the 120v ones they use on baseboard heaters. Most grow shops carry them. You will also need a dehumidifier and an AC that can...

This is a very entertaining thread to say the least. 1000KWh can easily be excused with a computer, HDTV, and a 120w bulb. That is one bedroom. Add another 1000KWh for the living room alone, and another 1000KWh for heating/cooling/water and sewer pumping/freezer in the garage/power tool...

If you have four reflectors/bulbs you can use two ballasts controlled buy a flip flops and a timer. This way you can have your ballasts constantly running so they never powering off, and every 12 hours the power can be flipped from two bulbs to the other two. This way you could have 2 rooms...

I don't know about the airlock valve, but you probably want to use sugar and not salt.
