Can I just eliminate the capacitor all together? I dont know exactly what would change if I did that, but the ballast i'm using now doesn't have a capacitor and seems to be doing ok. Could anyone explain the difference, please?

Well, taking more of these suggestions into consideration, I'm going to eliminate the flex altogether, and use rigid, fixed cool tube in the flower room, using adjustable shelving to move the level of the floor. Here are a couple of new screenshots showing the entire system outside of the...

I like how we are both trying to exhaust 3 spaces with one fan, and taking different approaches. Some thoughts on your shared exhaust box - First, having the exhaust down low in the clone room is not the best place for it - why not just use 1 or 2 pc fans up high and use more fan power for...

great harvest man! I really want to try the drowning method here on my first grow. I think I'll be harvesting sometime early-mid november. Good job on the experiment - I'd like to see updates on the cure process!

Some updated pics here of the LST plant. It has 5 large shoots including the main cola. The secondary shoots have stretched quite a bit in the past week, which seems kind of late for stretching. Main cola is getting fat at the base, and is pretty filled in, i'm hoping these other arms fill in...

Well, these Tjerlund fans can be mounted horizontally or vertically, no problem. They can be speed controlled down to 50%, but anything under that, and they can start to burn out the motor. After researching muffler devices, I think i'll build a little chamber in the bottom of the cab, lined...

so your box is a total of 80"x72"x20"... I'm wondering if you really want the flower room to be 6' high - do you really want plants that big with low lying buds that get little light? (obviously a personal preference issue) I would think about the ventilation strategy - - have you sourced or...

Cruzer: thanks for stopping in! I'm using the 4" mainly because it is the most available and least expensive. I hear you on the 2" ducting, but I really want to keep everything inside the cab, and I'm ok with having so much space for utilities. I only want to flower 2 plants at a time anyways...

@TheDude - Everything must be enclosed inside the cabinet, unfortunately. I am moving to an apartment (w/ no roomates), so there will be people above and below me, but no balconies, (and no more cleaning lady to worry about - so I can have a bit of noise but not a hell of a lot - i'm getting...

Thanks a lot everyone for the posts so far! Questions answered in no order: 1. The extremely large amount of utility space is due to optimizing the air flow. For example, using 45 degree connectors instead of 90˚ T connectors really adds a lot of length to the ductwork (but really saves on...

hey Cruzer, can't wait to see the rest of the harvest - its pretty mind blowing thus far! So, I'm working on a new cabinet design now, and would like to get your opinions, because your stealth cab was a pretty big inspiration. (you too, Gumball!) here is the link...

hah, very nice - - good thing you dont have to worry about that! At 50 days into flower, I barely have a smell going right now. BTW, i'm designing a new cabinet from scratch that I want to get started on soon - and would appreciate any criticism. I'm going pretty crazy on the ventilation, and...

hello there RIU'ers After building a semi-stealth veg & flower chamber into an existing cabinet, I'm wanting to build a whole system from scratch, which will be 100% light proof and have super-optimized ventilation. I am so concerned with the ventilation, that I'm building a whole separate...

thats right, I meant volts, hah. Well shit, the lamp is good because I switched it back to my 220v ballast with transformer and its working fine. (I was trying to lose the need for a transformer). So its probably a bad capacitor? is there a way to confirm that?

Thats right, I meant volts. I'll check out the capacitor, but if its overheating, is the only solution to get it out of the box? thanks a lot

I am hoping you can help with a ballast problem I'm having. This ballast i wired together will start up the 150w HPS light, run for about 10 mins, completely turn off, and do this over again - it can't seem to stay on for over 10 mins. Its a 127w ballast with a capacitor, so i think it could...

Yah, I'm looking forward to the poofing! [theres one for all the UK riu'ers] Well, this is Doctor Atomic's strain, which is "Northern Lights crossed with the worlds best sativas" so maybe thats why its looking a little indica-y to ya. (to me, it just looks pretty and green, as its my first grow)...

hey thanks for the reply, D! So the girl above spent 3 weeks under 1 cmh? it looks great (I thought you were maybe using 2 cmh's side by side) Its giving me some great hope with my 150w hps. I'm thinking of going to cmh too, and modifying my hps ballast to run a mh and use for vegging. Youre...
