Lol I was going to bring up that 2 hps 150s is another affordable option.
Think you are going to need a temp controller for the fan? Or not much changing in terms of air exchange volume?lol lol........ How true!
My floor fan is a beast, it's actually an outside fan and is very powerful. That's why where I put the Phresh Filter is important, I didn't want the fan blowing straight into the filter. I think I have it figured out, I'll just need a new hole in the ceiling and plug the old hole.
Honestly I think its something most really struggle with and I couldn't agree more when you have that control it just eliminates so many issues and you can dial things in time and time again because of the stability your never left wondering what change is the culprit or the benefit. Temp is just a huge huge factor and all things change when the temp changes... humidity... well there is a lot of wiggle room there between 40-65%I have a temperature/humidity monitoring device mounted and I'm in there 10 times a day........ I use the exhaust fan controller to adjust the heat and humidity. The dehumidifier keeps the room fairy warm at night, I try to stay within 5-10 degree spread between day and nights. Either way, an unwanted stretch does not appear to ever be a concern again.
The exhaust fan moves around 862 CFM which is a lot in such a small room. As I've said, the negative pressure in there is such I have to fight just to get the door open. LOL There's no doubt one of the reasons for my success is the ability to control temps and humidity to an exact degree.
I would start with bursts and watch like a hawk for negative effects.I’m still trying to figure out is it better in bursts, let’s say 10 minutes on 12 times a day or just run it on for 2 hours on and then off the rest of the day???
Maybe start small and work up but I would prob alternate 1 on 1 off in the end at that intensityI’m still trying to figure out is it better in bursts, let’s say 10 minutes on 12 times a day or just run it on for 2 hours on and then off the rest of the day???
Good to know... so consecutive it is. Makes sense as to mimic the natural sunSome further advice form CLW..........
"We recommend 3 feet from the plants. We usually start with smaller periods of time and increase it slowly as the plants get used to it. Try to position the on period in the middle of your flower time. Just do it for 30 minutes 6 hours in. Increase to an hour after a couple days and so on until you have it on for a couple hours per period. Sativas can handle it better than a broad leafed Indica can."
Thats probably twice as much needed for your room..mines not quite that big only 710cfm i do near same lol using exhaust fan controller...i too battle to get out of room lol and thats only on a tad under half speed.i gotta put my back to the door and use my ass to bump it open with great difficulty and near fall over plantsI have a temperature/humidity monitoring device mounted and I'm in there 10 times a day........

Higher by a foot.Thats probably twice as much needed for your room..mines not quite that big only 710cfm i do near same lol using exhaust fan controller...i too battle to get out of room lol and thats only on a tad under half speed.i gotta put my back to the door and use my ass to bump it open with great difficulty and near fall over plants..those soft door seals work perfect..
So this uvb light will b hanging a ft lower than your light or will it b at same distance as the gavita towards the end of grow..
Based on caution is all.Based on what???
This is great stuff! Thanks for sharing!I've used this light for almost 2 years now.....did side by sides, etc. Here is the schedule I've found works for most all strains.
Definitely keep a 3ft distance from canopy at ALL times.
Make sure you or your skin is nowhere near those lights when the red light on top is flashing!
Week 1:
Day 1 - 30 minutes at midway (Hour 6 of 12)
Day 2 - 1 hour at midway
Day 3 - 2 hours at midway
Day 4 - 2 hours at midway
Day 5 - 2.5 hours at midway
Day 6 - 2.5 hours at midway
Day 7 - 2.5 hours at midway
Week 2:
Day 8 - 2 hours at midway
Day 9 - 2 hours at midway
Day 10 - 2.5 hours at midway
Day 11 - 2.5 hours at midway
Day 12 - 2.5 hours at midway
Day 13 - 2.5 hours at midway
Day 14 - 2.5 hours at midway
Some strains are really sensitive, but usually the fatter the leaves the less they can take. Not always the rule.
Make sure you inspect at each interval for negative effects. Basically to much will turn the plant matter brown, and degrade trichomes.
Have only seen a couple strains take more than about 3 hours. More testing is needed, ie - splitting duration times to 2 hours at midway, then 1.5 hours during the last 1.5 hours before lights out.
You will see a difference in just a few days of use. Its noticeable.
