  1. Hi everyone, I'm super fascinated with the 1000w DE Bulb comparison I read on growershouse a long time ago. I'm going to run my own trial soon but I was thinking, is the ballast choice just as important. Or is the variation too small? I currently run an adjustawatt, and from their review was planning to trial the Phillips Greenpower 1000w 400v DE bulb. It's £160, so was curious to the impact of upgrading my ballast as well. What do people think? I can't find any ballast comparisons online sadly.
  2. Hi all, My HPS 600 watt bulb is blinking, but not turning on. I do one small grow with it, per year, as I am a light user. I think I've had it 3 or 4 years, and its only on for 4 or 5 months a year. 24/7 for vegging, 12/12 for flowering. Is it possible the bulb has just reached the end of its lifespan? I am hoping thats all it is, and not the ballast. It was working fine at the end of last years grow. Moved my young plants into the grow room today and it wouldn't start up. It's just stuck on blinking. Anyway, ordered a new Omega dual spectrum 600watt bulb that should be here by Wednesday. Hope that does the trick! Cheers.
  3. Hello Herbalists, So i purchased a Solis-Tek 1000w Dimmable Digital ballast and im looking to run it paired up with a double ended reflector and bulbs. My tent size is 120x120x230, and i plan on running a 600w MH bulb for veg and a 1000w HPS for flower. im just after some advice on what bulb brands are the ones to go for as i hear some bulbs do not like the high frequency of digital ballasts. also, im looking for a little help sourcing a DE reflector and the DE 400v bulbs as im not having much luck. i assume links are not allowed so just the name of a place will do,here or pm. am i correct in thinking that MH bulbs are not dimmable? Thanks.

  5. Hello kind people I've been researching for a good month now and spent most waking hours (many when my mind should have been on other tasks, of course), reading and thinking, designing and redesigning.... Having (actually) perfected the design, I just need to figure the ballasts and bulbs. I'm getting impatient now and what I can find on these is mostly slightly dated so I'm tired of trawling and want to hand over to people who would just know - I don't run on diesel and my head hurts. I need: 300 - 500 w during veg. . 800w during flower. Spread over 2 bulbs Fluoros are, for various reasons, out - even as supplemental This necessitates dimmable ballasts. CMH look too good to pass on. But quantity is, unfortunately, a concern (first grow, probably stupid to treat it as anything more than a learning exercise - but I've invested enough mental energy to care now). Would they do for the whole grow, or should I switch to HPS (maybe dual spec.) for flower? Future grows are a consideration. If I'm going to switch, should I just get MH for veg. as they work happily with most newer ballasts? The footprint from the lights isn't really going to cross over so running 1 hps and 1 mh/cmh for flower would be of little merit except for experimentation. So basically, I'm asking for advice on the compatibility of bulbs and ballasts - are there now any digital ballasts that can handle CMH or any CMH bulbs that can handle a digital ballast? I read that lumateks don't work well with certain bulbs due to their frequency and/or striking voltage mismatches. Any knowledge on this? (I'm leaning towards lumateks bt haven't gone so far in researching due to aforementioned headache). Complete ballast and bulb combinations suggestions most welcome. No absolute limit on spend but I'd obviously like to spend as little as possible to achieve my goals. Energy efficiency is also a significant consideration of mine - partly why I'd like a ballast of a newer design and so partly hence this post. Suggestions of places to buy (in UK) also welcome. I can't help but marvel at the generosity of spirit on these pages, and when I am learned enough I fully intend on reciprocating. But for now, I'm still a comparative dunce and would like to lean on the community's knowledge - I know I could find proper conclusions to these questions with more fishing but would really just like to get on with it. Thanks and peace
