Running a perpetual system is a lot of work and since its your first grow I would just do 1 harvest at a time for now and get a 2 or 3 harvests done then tweak and change the setup.

I have my timers 15-20 seconds apart

Yes there is a pi it will control 8ssr for uvb lights and there is 2 dc ssr to control the power supplies the ldds they are for 660 and 720 they will be on all day it will also control co2 and have temp humidity sensors throughout the garden its a big project and a lot of wiring. Converting 4k...

Stranded wire or soild core makes a difference you can push more amps safely through a solid core wire http://www.engineeringtoolbox.com/wire-gauges-d_419.html Using C class breakers is not that hard but the planning is the difficult part if you are unfamiliar with it. They are also more...

yes it would but you will need a 12v driver for the fans

OK the driver cant be 50w 36v and 3a it would be more like 120w driver 36v 3a There is 2 different ways to wire these chips on way is in series and on way is parallel. It seems like you are not sure of what you have or what you are trying to do. If the driver is 120w and has 36v and 3a you can...

What size space are you going to light up with them? Active cooling is better than passive you can use a smaller heat sink for higher wattage. The clu048-1212 to replace a 1000w hps in a 4x4 you need at least 12 cobs but 16 would be preferable driving them @ 1.4A now you can drive them harder...

I understand about just upgrading, do it in steps over time yes it is hard and we want to do it all now but sometimes the finances are not there. Led is a little more than that to equal or surpass what you can get with hps. There is a roi calculator...

The reflectors I used when I ran hps were dominator xxxl but if you are looking at adding new lights look at cob leds

Its q qball glad i was able to help you can get containers any size but it maybe cheaper to look for a used barrel Its easier to put fans and a filter on a shelf than it is to have a res.

I am a firm believer you get what you pay for. If i was getting new fans I would look at hyper fans. Yes they are a little pricey but the advantages outweigh the cost. The hyper fan also comes with a controller. If you want a temp controller they have one also. http://www.hyper-fans.com/ They...

Here in colorado we have the opposite problem the rh is 10%-15% you can dry buds in 2 days. One type of filter material I thought of is for swamp coolers and use it as a prefilter that can be washed and cleaned but its not level 7 filter Maybe just spray lysol on the filter area monthly during...

Have a look at the 4" inline fans once you add a carbon filter to it you will loose 25% of its rated cfm. That is with any size fan and filter. http://www.htgsupply.com/products/growbright-4-inch-inline-fan-carbon-filter-combo I dont run in tents so my experience is a little different I would...

First thing that comes to my mind is getting a filter for a furnace a little bigger than the louvered opening. You can build a wood frame for the filter to sit in leave it open on one end so you can replace it.

Since you are using a bathtub I would guess there is a sink or toilet. I would tap into the water supply for the either one and run 1/4" line to a float valve in your res. I say tap into the water supply so you can use the pressure in the line to move the water cold side of course. Home depot...

First how far away from the water source is the garden and plants? Are you going to want the reservoir to automatically fill up stay full all the time? What size is the reservoir you are going to use the height? How far away will the reservoir be from the plants? I'm going to suggest to use...
