Awesome! Indoor is fun but you tend to look too much
.
IMHO!
I would got HTGS, awwwwesome place I used them. Stick with the 600 digi, aircoolable 'flector, however scrap their bulbs, go to your local shop and support them by buying an Eye Hortilux Super HPS.
Next I would also ebay it for a light mover (don't buy the chain version) unless your local shop will be nice and work on the price. My local place is amazing, however they charge $300 lol. This will give you tons of room, and keeps temps and usage down.
In your veg room... Well, the same setup w/ a 400w MH would be nice (what I use)...
For system... well I would suggest you build a nice NFT setup with 5x5 post, but your power issue is scary. I worried too so I built this.
X - Black handle less buckets
X - Bucket inserts, I use 10" but I work up to it, your choice, 6" would be good!
X - Barbed T fittings
X - Rubber O ring seals
X - 1/8" barbed drip fittings
X - Blue drip spikes
Xft - 1/8" drip line (cheap get a ton)
Xft - 1/2" drip line
Xft - 1/2" Blue tubing (connects lines)
Xft - Air hose
X - Air stones (as many as buckets plus one for res)
1 - 20-50 gallon res of some sort (must be taller than buckets)
1 - 400+ GPH pump
1 - 1/2" drip line end cap
1 - Air pump w/ many outlets or a mani with many outputs
LOTS OF HYDROTON
Now let me explain this system and why it should work well for you...
The idea is that the res has two low mounted barbed T's one on each side. Each bucket will also have a T. The buckets will be connected with the blue tubing to the res in a "loop". Setup an airstone in the res and one in each bucket. Drill a small hole for the air line in the pot.
Now setup your pump in the res. Take a piece of 1/2" drip tube around 2ft. long. Insert however many barbed 1/8" drip tees, just twist and it will pop in to the tube. Now install the end cap on the main drip line, plug it all into the pump and set in bottom of res. Now fit your 1/8" drip line to the fittings and run those out of the res.
At this point you can fill the system, you should not have any leaks, it is a pretty easy setup. The bene here for you is that it creates a DWC system in the pots that will allow the pants access to some nutes, the hydroton will also pull the moisture from the air if the water is not hitting the pots. You can control the level by checking out your res. When it is working normally however the system does a great job of circulating the water. I run my drip system 24/7, as we all know the entire system wants to be at the same level so as the drip lines slowly fill the buckets with water from the res, old what is forced through the blue tube back to the res.
You can also add a nice little ebb/flow table to the system. This is a great place to transition your veg plants to flower. You can then dump them in the buckets.
Hope this helps, if you have any questions just ask!

and it sucked. It almost felt like I lost a best friend or something.
