Are you going to use a propper Cool-Tube or one of those 'Bake-a-Round' tubes... I am going to use the baking tube and modify it.. I know HPS comes with a lot of heat but how does it compare to a 150/250W HPS...Just trying to get an idea of what CFM fan/s I will be needing !?? - STELTHY
My cool tube came with a MOG socket in it and its rated at 2000w but since my lights are only Med base I can use any ceramic light socket. Always use ceramic light sockets because they are safer to use and they can help take heat away from the lamp.Are you going to use a propper Cool-Tube or one of those 'Bake-a-Round' tubes...

Hey man, I like what your doing. That cool tube looks perfect. And scrog is definitely the way to go. I did one of these a few years back with a 70 watt hps also and the ventilation was the hardest part. It was soil so that probably makes a bit of a difference. Also had a makeshift wind tunnel. i started with one small computer fan for intake and one for outtake by the bulb. That ended up drying the one plant out too much. Ended up on running the one outtake and having passive intake. It was a little hotter, but not bad at all under the plexi glass (mid80's). I didn't have a carbon filter either so i am sure that will effect things. I am sure space is an issue too but if you could get a sepereate fan for just the bulb that takes air from outside and puts it back outside, and then another small one for intake with the carbon scrubber that would be awesome. Had to do with the space but awesome.Are you going to use a propper Cool-Tube or one of those 'Bake-a-Round' tubes... I am going to use the baking tube and modify it..

I've been on You-Tube and found a few videos of the above Phillips 70W HPS lamp, I'll list the videos below :-
Ok I've just been searching on-line and found a 70W HPS bulb for around £5 (new)....So I bought it!! I guess it'll take a few days to arrive, but I'am in no hurry! Now I am going to try n find a 70W HPS Ballast/Security Light I can hack

Do you plan to put the ballast in metal housing etc.. to protect it, and yourself from shocks etc ?? how do you earth it?? I like your components

Here's a pic of my cool tube that I have but haven't gotten the inline fan and dryer hose tubing for it so that I can use it.
Here's a pic of what my ballast looks like after its been wired.
I'll have to settle for the bake-a-round due to the size of the P.C cab. Did you have to wire the ballast yourself or was it pre-done? - STELTHY
The only thing I might do with the ballast is put it on some thing and have a fan blowing on it to keep it cooler. I had to wire it my self. The 70w only runs off of a 110v circuit.Do you plan to put the ballast in metal housing etc.. to protect it, and yourself from shocks etc ?? how do you earth it?? I like your components
Sounds excellent.. I may well be PM-ing you for the odd bit of help here n there.. I plan to have separate cooling for the light tube (bake-a-round) and a 2nd air in/out-take for the actual Growth-Chamber.. this should regulate the air-flow and keep temp & humidity in check
- STELTHY
If I use a similar ballast in the UK will a step-down converter be needed ? I will defo be using a mini fan to cool it down
- STELTHY
Sounds good. I am not sure how much less evaporation you'll have because of the closed container. Going to have to gauge it by plant. With the soil I had to add at least twice a day to keep it moist when 2 fans were running. Here is a link to that grow I did. https://www.rollitup.org/grow-journals/164898-pc-scrog-6-week-flower.htmlSounds excellent.. I may well be PM-ing you for the odd bit of help here n there..

Cheers for the LINK dude - STELTHY
I just thought about this and a RDWC might be a very good way go if your doing a PC grow even though the res would be out side the case but it males it easier to top up, PH and change the water. You use a water pump in the main res, you use drip feed way. If you run 1 tub have a tube going from your tub to your res so the water keeps moving and put air stones into your tub and there you go.
What size P.C case did you use ? Do you know the dimensions ?? - STELTHY

I just went to a small computer store that had a lot of cases and things for you to build a computer ground up. Bought the biggest case they had. It is 6inches wide x 18inches long x 20ish tall.

Thats great, cheers man! I'll go on the hunt for a similar one in the morning

Whats the difference in size between a Server Case and a Full size case ?? which is bigger ?? - STELTHY
