New City Grower 1.0

Re: New City Grower

I killed my house plants in the winter for years because I was giving them softened water, salt build up. They are now flourishing using the hard water from outside well. The difference has been amazing.

Re: New City Grower

Do the judges mind if we go 5 or 8 extra minutes. this is Rico's 1st time & he's done a good job but I want to get these prizes out

Re: New City Grower

Also you are a proud recipient of the reps I'm about to endorse to you...

Re: New City Grower

600w is more efficient than 400w, not just stronger. Watts to actual fc & luminosity is big hint.

Thank you all for participating & for your pleasure here are some lovely pictures from some of our 420 members.

Good Night...

Re: New City Grower

continue,
cajun is spot on with watts to lumin ratio, 600 is the best watt to lumin, but thats only watts to lumin and not including the par value

i never seen a journal move so quick, my f5 button has wore out, my pointing finger is an inch shorter, can i claim compensation for repetative f5 injury, my finger is damged for life

Judges rock

and judges rule.

Judges say

"Continue, it's cool"

Re: New City Grower

a 1000 watt High Pressure Sodium light will provide 139,000 lumens or greater and the highest lumens per watt ratio.

 

[donpaul.p]

Re: New City Grower

watts to lumin ratio the 600watt answer is the correct answer,

Re: New City Grower

>>> How is it possible for PM to flourish even in low humidity environments?

Fungus spores are almost always present in most homes. The reason they start to develop is by providing optimal environments for them to strive and multiply. High humidity and high tempretures are two key factors for rapid PM development. For them to flourish in low humidity envrionments means that YOU already have the spores present in your grow room.

Symptoms

White powdery fungus grows on the upper leaf surface of the lower leaves.
Leaves may be twisted, distorted, then wilt and die.
On some plants such as kalanchöe, infected leaves have dry, corky, scab-like spots and fungal growth is not obvious.

Conditions Favoring Powdery Mildew

1 High relative humidity at night
2 Low relative humidity during day
3 70-80F (22-27C) temperatures (These conditions prevail in spring and fall)

The spores are carried by air currents and germinate on the leaf surface. Liquid water on leaves inhibits spore germination. The fungus grows on the leaf surface but sends fine threads (haustoria) into the cells to obtain nutrients. From the time a spore germinates to the time new spores form may require only 48 hr. High humidity favors spore formation while low humidity favors spore dispersal.

Some powdery mildew are inhibited by free moisture on leaves while others are favored by wetness on leaf surfaces.

>>>Which HID light has the most efficient watts-to-lumen ratio?
(400, 600, 1000)


Why is one more efficient than the others?

I say 600 and that's all with a bit of math. The 600watt has the highest lumen per watt output (146.6 Lumens per watt) in comparison to the others. Now it all depends on the size of the grow space to consider which one to be more efficient than the others.

Re: New City Grower

the 600 is the most efficient and in thr uk i've heard the big cats use 600s because at the end of the chain they have far more total lumens available because they can be much closer to the plants, i dont remember where to find the data but i did the research before i got my dual 600 setup

Re: New City Grower

OK give Cajun the last prize & lets discuss Ridding the grow area of Spidermites during open discussion.
Rico you did great with only a couple of hours of prep. Reps to you also.

Re: New City Grower

@king, are you sure, i was always under the impression the 600watt hid gave the highest watt to lumin ration, but hps is different to mh and bulb brands can vary by 10,000 lumins, i can buy 55,000 lumin hps bulbs and 65,000 lumin hps bulbs for my 400 watt, so if i used 2x 400 watt 65,00 lumin bulbs id be using 800watts and getting 130,000lumins but thats with hps bulbs

 

[donpaul.p]

Re: New City Grower

the main course for pm issues is stagnent air around the plants and grow medium, if you dont have good air exchange or good movement of air then this is ideal conditions for pm issues, if you have good air flow at plant level and between plants then you shouldnt have pm issues unless the humidity is way to high

Re: New City Grower

Lumens are a scale of brightness and do not add like you believe they do, there will be more light but not double the amount.

Well going by the average lumen output of each bulb the 600w is the most efficient.

400 watt:
Initial Lumens: 55,000

600 watt:
Initial Lumens: 88,000

1000 watt:
Initial Lumens: 145,000
