CFL Cardboard Box Grow some NEWB advice needed

[freshpl]

Need advice on keeping the heat down testing out the setup I'm at 100F

-Will be adding 2 pc fans will see if that keeps the heat down.

-also I have 6 CFL 26w 6500K for veg. Too many lights?
5 plants will be in the box Blue Mystic I will use a different box for flowering

Make sure airflow is optimal. PC fan at the bottom bringing cold air in, then exhaust at the top to get the hot air out. With tight spaces temps can be a problem.

The plants will need all those lights, just keep some air blowing across the plants/lights. You might want a fan in there to circulate. Hope that helps.

thanks ordered pc fans will install and update, the cfl's 26w get really warm to the touch I was quite surprised

You're going to want to upgrade to 43W bulbs for flower (and for veg if you can get them quickly). 2 43W bulbs per plant is what Ive seen deliver good results; anything less and you will get a lower yield. I realize you're growing in a smaller space, so you may have to cut down on number of plants you grow, say 3.

I am doing a similar grow. My box is kept at 75 -77 deg F constantly by 2, 5 watt PC fans.
They are placed over the bulbs, and so, extract all the heat directly.

You can check it out for ideas.

I will be adding 3 more 26w 6500k and 1 2700k @23w instead of the 43w based on the heat issues in such little space.

- I will also be adding a homemade c02 to lower the temps

C02 won't lower temps, in fact you want to use C02 with higher temps.

Not necessarily. Adding Co2 to a grow means you can have temps higher if you really wanted.

Add some intake fans and some out take fans.

If you bought one small RVK fan you could use it as an out take fan, this would solve your problem completely.

That's what I meant/said; you use C02 when you have higher temps to combat high heat when its not always easy to cool the air down. Also to give your plants some love

How did you get that power strip secured on the top?
