Lighting up a small veg tent.

well I have decided to set up a small veg tent.
I have a trash can set up that I built for shits-N-giggles. It works very well. But by design it’s a pain in the ass for me. Lol.

I like to tinker and try different things. So over the years of changing and playing with my grow rooms. I have a “selection“ of lights to choose from.

right now I have just a single 100watt cob in my “ trashcan” thing.

32gal Brute trash can grow

Hi guys. I built a 32gal space bucket grow system. I have only used it as a veg chamber for my flower tent. But I am going to run one all the way this time. Light is a mars hydro 100watt COB. Lemon CBD auto 2L Perlite/hydroton Hempy bucket. 20/4 light schedule. I have topped once and...

My new tent is a little odd size. But I think it will complement my 3x3 flower tent just fine.
It’s 20”X 36” X 62” high.

For the sake of more info
I start seeds in 1.5” rock wool cubes
Then in red solo cups for 2weeks
Then into 3 or 5 gal 100% perlite hempys
6-8 weeks from seed then into the flower tent.

I am contemplating cloning off my plants before they go into flower and stop cracking seeds and just stick to 1-2 strains.

here are my light options.

2x Mars hydro 100watt single cob

400watt MH

2x 250watt CFL 6500k

T5 24” 6bulb 144watt 6500k

what would you put in it?
I know they will all work. Just looking to have a discussion
 
Any reason you don't want to go with an LED?. It looks like you are already have a Mars Hydro product. I have one of their TS series LED and it works well and I have had no issues. One of the smaller ones like the TS1000 are pretty cheap, would work fine in that size tent, would run cooler and use less electricity.

I think leds would be good. Just trying to decide what to use.

If you already have these, this is what i would use. 40w/sq ft should do nicely for veg.

Yes I have these ones kicking around.
But to he honest I have trouble keeping the trash can thing warm enough with one of them.
might need to put a small
Heater.
 
Well if your going for a small space, definitely want to look into LEDs for their higher efficiency so less heat.
 
The cfl would give you some hear in that space, cfl, T5s and mh all veg well I'm not familiar with cobs.

Where are you growing? Outside in a garage or something?

it in the bacement of the house. I have a extra room. That Part of the house is below ground cement foundation.
Anyway it stays cool. 65*F. My trashcan thing works good at 75F. But if I set my controllers to 80F-85F. My exhaust fans don’t cycle enough IMO. I don’t think I am getting enough air exchanges threw the day.

75 should be fine for veg.
 
My flower tent is all Cobs. I run at 82-84 and 60-65% humidity. I do lower those gradually towards the end. Usually 75-78F and 35-40% RH by the end.

Really? I always thought you needed to be warmer. Especially with led and leaf temp.

eveything is growing fine at 75 but wondering if it would be better at 80-85

For flower its important to keep temps up but i think they will veg just fine at a lower temp. You could always toss one of these bad boys in.

I have a 400watt MH with a dimmable ballast. I just don’t know about the heat. In that small
Of a place. Might need a air cooled hood.

Yeah you could get a 250w mh bulb if the ballast dims to 250..... Running a 400w bulb at 250 isnt a good idea from what i understand.

The ballast dose 25% 50% 75% 100% then super I believe.

75% would be 300watts. Could a 250watt MH bulb work on 300watts?
