I was wondering if any of you experienced growers who have had plants on a 24hr day cycle could give me a little info.?? I have always had either a 16 or 18 hr. day cycle but have recently heard from an unrelieble source that a 24 hr cycle makes a big difference in the growth phase of a plant. Can anybody second this? I would think that a plant would need some sleeptime as well..... am i wrong?? thanks respect..

i have a 400 watt HPS bulb and ballast combo. i got it from a friend, who had it rewired for some fucked up reason. there are three wires in the cord itself, red(which is disconnected), white and black. inside the ballast there are 3 or 4 wires that are not connected. the white and black wires are then attached to a two prong plug in. he said that the light worked in his dryer outlet. but i would like to rewire it RIGHT and get the full light.

Hi ozstoners, I have been growing for ages using 600 watt hps. A while ago I was given an 880 watt hps globe that runs off a 1000 watt mh ballast. The last few grows I have used the 600 as a veg lamp then switched up to the 880 globe to flower. I have always been under the impression (don't know how correct I am though) that hps was a better lamp for flowering due to the more orange light spectrum than mh. I am now wondering if it is worthwhile getting a 1000 watt mh light to flower with as I already have the ballast. Has anyone compared the results from the 880 hps side by side with a 1000 watt mh lamp? Also if I am running an 880 globe off a 1000 watt ballast is the b…

I guess this one is probably for experienced growers who have experimented with different light sources, or those who read a lot.. I am wondering about using fluros in the veg cycle. Will they give me as much light as hps(400's)? or will the plants growth be slower with fluros? I believe the best fluros to use are the tri-phosphor, is this correct? Is there a combo of fluros you can use? What are the advantages/disadvantages of using both. I know i am asking for a lot of info but have always used fluro to seed/root or clone and then hps to veg and flower. I realise the fluros dont make as much heat and cost shitloads less to run but is this their only advantages? I found …

hi all, wondering if a 1000w bulb can be used in a nova shade .... i bought a secondhand 1000w bulb, ballast and the shade which is a "chinamans hat" as they guy called it but it kinda sux the bulb can only face downwards giving me alot less height and would prefer it going length ways. can i use a nova shade (i have one from my 400w) or what sort of shade can i use ? thnx

Just a few questions: What do ppl prefer vertical (eg chinabowl) or horizontal lamp (eg.lobay) and why? Any ideas on the dimensions of these lamps light coverage, is a vertical lamp a circular coverage and a horizontal lamp a more rectangular coverage if so what would be optimal for 400 (approx 8-10ftsq)or 600w (approx 10-12ftsq) son-t-agro (and is $205 a good price for a basic 600w son-t-agro light kit complete? source: nutriflo hydroponnics in Gosford NSW, and on the net) I am not sure about the strain but as a general rule of thumb what sort of distance would you put between two plants (minimum)? Thanks for all the indirect help from everybody that has contribut…

i was wondering how much it would cost to run a 400w hps (ballast) for 24hrs a day (monthly cost) thnx

hey anyone experimented wid using strobes for supplemental lights? i had a couple of younguns under a 4ft growlux, spotlight n srtobe as well as underfiltered patio light during the day. overnute tho n they went all saggy ill b tryin again in a minute... anywayz. input badazz... oh btw, i read sumwhere that there wasnt a difference in growth habits wheterh the tube was cool white, warm white or growlux, is this tru, or what is the best combination coz i just use all growlux, first time usin random lights its usually a 400hps

600w hps setup seems to cost more than 1000w hps setup. Why is this?

I was wondering I have 4 foot wide by about 6 foot hight and 6 foot deep grow room I also have a sunsystem 3 comerical 1000 watt hps Is this ok. I keep it vented and airflowing into the room. What about the yield aswell 10 plants in rockwool in a ebb and flow system

i finally bought my Son T aggro 400 watter a few days ago and plugged it in last night to test it. It didnt look strong at first but started to glow brighter and brighter and the globe turned orange. I was kinda worried it was gonna blow up or something, maybe it just looked bad coz i was stoned heh does that sound normal for one of those lights? i just wanna make sure before i set all up. also would they be too strong to germ under, its just that it will keep the seeds warm, the others i tried in water didnt germ probably due to the water getting cold i spose?

check out this web page http://www.sunstreamer.com/ they make a claim that there light system that use 100watt can be a par with a 400wMH HID.

i was reading on a web page the other day about a new lamp that can flore plants under 18 hours of light on and 6 off. The lamp producers a certain spectrum of light that causes a hormone change in the plant, enabling the plant to flore for 18 hours straight per day Cutting flore time by almost half. Sounds like the shit -----> has anyone heard of such a product?
