T5 Lights

[tao dog]

Hi, I'm new about growing and I got a question about light. I have a baby plant, and I don't have that much light in my house. I bought a sunblaster T5HO 2 feet. It originally comes with a 6400k. Should I stick with that until the plan is full grow then change for a 2400k bulb for flowers, or should I get the 2400k from when they are baby to the end? thank you

Are you going to finish your plants inside or outside?

Your 6400K lights are perfect for vegging. Once the plants flower you can then switch to the lower K lighting.

Hi! I see that this is a few years old, and I am hoping you are still on here!

Hi! I see that this post is a few years old, and I am hoping you are still on here!

I am brand new to the game and there sure is a lot to learn! I am hoping that you could help me with something...

I have T5's, 4' x 8. I just now realized that I need to change bulbs, the unit came with 8 6500K bulbs. I ordered the red ones for blooming and I have a couple questions...

When do I add the red ones? My autoflower plants have been in there for 3 weeks.

Do I change out all the bulbs for red or a few, or every other?? What is the secret??!!

Thank you in advance for taking the time to help out!

I assume you mean 8 bulb 4' fixture. A pretty conservative plan is..
Leave the 6500k bulbs until your autos start to flower
Change out 2 of the 8 and run like that for a week
Change out 2 more for the second week of flower until the stretch is over
Change out the last 4 to bulk up flowers for the remaining 4 weeks or so. Look for 2700s or 3000s. Maybe even mixture.
Some people suggest keeping a blue or two in for the duration. I wouldn't but can't make a good argument against. Key is to keep the plants low and wide with CFLs as light spectrum is good but penetration suffers a bit. Good Luck!

Hey Golden can I ask what bulbs are you using in you T5 fixture 54w or 24w?

Do CFL's give off much heat ? I like you way of using them with light coming from the side, I also plan to do this with the T5's for the lower canopy when flowering

T5 lights work great my sunsystem 4 ft by 2 ft was perfect for 3 large plants and with fans you can keep it within 2 to 3 inchs from top only problem is getting light to the lower buds i like to use cfls on reflectors i hang from the sides

I ordered a4'x12 bulb unit yesterday. it's 648w total paid 180$ free shipping. mix my light spectrum for optimized results running 54w HO with color temps from 2700k - 6500k. And there's allot in between there. I'm going under CFL lights ATM. 120w actual. .. per plant ..I have 2 s.a.d auto and one sin trabajo auto. If I could a photo uploaded I would. I've tried and nothing I seems to work. Btw this is my first grow. There 4 days old and the girls look as if there a week old. Heading for there 3rd node and branching like mad. I keep these lights about 1.5-2" above them. 6500k. Using fox farm happy frog since germination. With a good heavy mix of Perlite about 75/25 .I also put a soil thermometer in to monitor the temp in the root zone optimum is right about 68f. Air temps average 78f with approx 65-70%RH soil pH maintaining 6.7 with ph adjusted tap water. Started the girls on fox farm grow big this morning@1/4tsp to a gallon mix. That gets fed half way between the pot walls and plant base in a circle around them. Each get about 2 cups of water/2-3 days 30 minutes before the lights on. I run 18/6 schedule. Not like it matters there autos.. But I could force them to flower with less than 12 hours of light for 3 or more consecutive days. But they won't be forced like that. I want to push the limits to see how maxed out I can get these girls and surpass the breeders notes on yields. Enjoy the fruits of your labor and be good to girls. Peace everybody

I use t5's all the way through. I get 8 plants in 3 gallon pots under a 2' X 4' fixture. 4X4 should allow you to have more pots!

I do switch the spectrum during flowering...

I grow all the way through with T5's. I love them. When I flower, I replace only 1/2 the lights with 'Bloom" tubes. works great for me.
