250w HPS Club And Help Guide

[Broseidon]

Thanks, that helps alot. I think my Ph meter is off, my distilled water is reading 6.4. So my runoff is still too low, probably around 5.8 which would explain why I have issues adding nutes.
Im picking up some Ph up/down tomorrow, and going to do a thorough flush with distilled water.

I always calibrate mine in coke (2.6ish) and milk (6.7ish) lol

tomorrow marks week 4!

A heatwave is hitting again, at this rate i'm going to lose all my plants.

Hate to hear about the heat wave...

Got distilled water(zephyrhills), milk and coke.
Distilled was 7.0, Milk 6.7, Coke 4.0.... I guess 2 out of three aint bad...

Used some Ph up and got my water to 7.6 and ran it through. Run off was 6.5 - 6.6, so I guess that is what I am looking for..

Question:
When I mix my nutes I should get the solution to 6.6 - 6.8 and water?

Some pics... One is looking like a sativa.. Think I am seeing white hairs, but was fooled before..

Im thinking of a 250w or 400w HPS for my grow?
Getting a 5" inline fan for exhaust.
39" x 13.5" x 80"Height
Can anyone give me a rough guideline on which bulb/ventilation would be best for my grow space
Any help appreciated.

250W is plenty for that size.. It should cover 36" x 36" Just keep them short and tight..

Not sure what temps you will be dealing with so its hard to say what you need to vent.
A 250W is not very hot, so as long as you have exhaust above it, and a good intake below it you should be ok..
Make sure you have a seperate fan inside to keep a breeze on your plants, you should be able to keep the light closer that way..

Thanks for the speedy reply +rep for that.
Just wanted a guideline, Think the 250w will be the best option considering my space.
Many thanks.
Do you know the average lumen output of a 250w hps?

 

[Kalebaiden]

I love my 250, I just wish I had of gotten a ventable hood.

Just make your own. Only thing is, mine doesn't vent to outside, it stays in the closet.

LOL, love the warning sign....

I think its around 28k avg for a 250W HPS... You can get a 26k bulb for around 15 bucks, or a 30k bulb for around 80 bucks...
I am using the sunsystem2 mh/hps switchable, and im not positive but pretty sure the bulb i got is 30k. Its not hot at all, and with intake/exhaust and a ocselating fan I keep my 50 x 24 x 6' box at 82f or under, which is only 4 degrees hotter than the house. its a little high, but best i can do and its still within reason...
Main things are noise, I have a few fans running so its easier to cool.

alright enough helping others, time to be selfish again LOL..
Back to my watering & Ph...
I will be using the distilled water, maybe not the most cost effective, but its simple and at a 7.0.
Should I Ph down it to 6.6 - 6.8 for watering?
I just want to be sure I get it right this time, I have Ph up & down, a meter, even have one of those useless soil Ph testers... I was planning doing another gallon per pot at 6.6 - 6.8 and checking the run off, if everything seems good I can add nutes the next time...

Im at about 11 days since switching to my 12/12, and figure I can get at least two feedings of Floranova Grow to make sure the branches are strong before switching to the Bloom...

From what I have read I should make my nute mix, test the Ph and then add up/down accordingly to bring it to around 6.6. Is that right?

Looking good. Nice even canopy so you should have some good top kolas...
