LED Aerospring Garden Grow Log

[Joefarmer]

Greetings everybody! This is my first indoor grow ever! Been doin' it outside for a while, and am now expanding my horizons. Here's what I've got:

3x3x7 closet
1 Procyon 100
4 23w cfls (5500k for veg, 2700k for flowering)
AeroSpring Garden w/8 3" netcups
4" computer fan in the ceiling for exhaust
1/2 reflective insulation board lining the walls
1mil. mylar on walls
20lb CO2 tank w/regulator
Liquid Earth nutes
Super Thrive for some extra spice
Bag seeds
Lotsa TLC

Lights are on 18/6, nutes are at half strength, will try to keep pH @ 6.8 and CO2 @ 1500ppm

OK, pH is 6.7 CO2 1000 ppm. Unplugged the exhaust fan to ramp up the ppm's a bit. Will probably set it to a timer. As of now the CO2 goes on for 2hrs at first light, then at 15min intervals until dark. Seems kinda like a double edged sword here; I need the exhaust but it's depleting the CO2. Setting the fan to a timer might help the CO2 levels but it won't help with odors or heat buildup (not really a problem with the LED) the room stays at about 70 w/fan on maybe 75-80 w/out the fan. Any suggestions?

Also, they're in rockwool & LECA. Seedlings are 5days old and are rooting nicely in their super bubbly/aerated environment. I will likely ScroG them.

Pics: 1. room now with 4cfls, The rest: notice the roots that was before any nutes.

I welcome any advice from you seasoned indoor growers. Especially on the subject of LED lighting. I'm sure I'll have plenty of questions along the way.

Also be sure to check out my outdoor Purps/BlueCityDiesel log!

i've always read, and i'm sure many around here will agree, that for co2 to be effective you should be using it in a sealed room.

I'm with shake on this one. You are probably just burning up co2 if you are exhausting often. The most effective use of co2 needs to be in a sealed room with an air conditioner or chiller and the only exhaust that is necessary then is to cool light hoods. The reason we run so much exhaust is to keep a fresh supply of co2 going to our plants, if you are adding co2, you don't need to move air to get more. Putting your exhaust on a timer would help co2 levels build, until it all got sucked out. You will have to figure out if it's worth it to deal with more heat or less co2.

You can always send the emitter and tank to me, I'd be happy to let you know how it works!! j/k Take care

Another thing is that the PH should be around 6.0 for hydro not the 6.8 your use to for soil! Hope everything goes good for you. I will check in from time to time to see how your doing.:thumbsup:

good call worm. too caught up on the co2 to pay attention to that.

good catch on the pH bigworm! i totally missed that. even 6.0 is a little high by most opinions. 5.3-5.8 is the ideal range, although some strains like it a tad higher.

thx everyone. pH down it is. And as far as the exhaust goes it was at 1000pm with the fan on which is better than whatever the ambient air provides. I'm not about to ditch it though. Too much $ invested at this point. I'll just keep an eye on the heat.

irydyum, i think we posted the same thing at the same time. lol. your post wasn't there when i hit reply! lol. good stuff.

we've been crossing paths all day, ping pong style.

bigworm, that rep was for irydyum. but you deserve some too! i've actually crossed paths with you a few times today too!

sorry, i'm blazed.
