So my grow room is built and I'll be using a 600w HPS for flowering 12 plants but before they go into flowering they will be cloned besides my clone dome I wanted to put them under T5 lighting probably a 4' 4 bulb for veg for 5-8 weeks @ 20,000 lumens. Do you think it'll be good enough for 12 plants to grow strong? I've done the research and everything says it will but I wanted to know from farmers who have used the same thx!!

And I want to know if you need much ventwlation or can I keep them enclosed for 12 hours a day since there is almost no heat

t5s dont put off no heat man and the air still gets stale....you need ventilation just not as much as with an HID. how big is your veg box?

T-5 4/4 won't be enough to veg for 5/6 wks but will work well until clone roots take. Maybe 2/3 wks and you will be running out of room. I have 12 under T-5 4/4 but they are small, once I move to a bigger pot they won't fit under that light.

Thx I know I still need to vent co2 etc. My question is,is 12 hours venting enough and you don't think 20,000 lumens is enough to veg 12 plants in a 2 x 4 area? All of them will fit under perfectly under the ballast since the 4'. 4 bulb is 2 x 4 hmmmm any one else have you tried @ the same? Remember I'll be flower under 600w HPS which is more than enough light to finish the job I just want to know about vegging. Maybe you can show some pix of your plants under same set up? Thx

that is NOT TRUE! they do create heat~! maybe not as much as HID's but they do....My T-5 keeps my grow room at 85 Degrees with no air......77 with a fan.


they do create heat, BUT i agree it will not be enough for that many plants for that amount of time.

Peace

Pictures of plants under 20,000 lumens and @ 12 plants is what I really want to see I know someone out there is growing under the same I want to see how well it works!

I started and finished with T5's ....was only TWo PLANTS but finished awesome! 10oz wet

Nice and I'm sorry I'm getting 2 4 bulb or 1 4 foot 8 bulb T5 for a total of 40,000 lumens I posted wrong so that's what I want to veg under. Sorry can we start over!! Thx LOL
