To bubble wrap or not to bubble wrap
« on: April 15, 2012, 07:48 »
I can understand that bubble wrap insulates a greenhouse but what I don't understand is why no one mentions that it cuts down the light............ Or does it?
I have never insulated my greenhouse, but given that I now need to move stuff to the greenhouse and the nights are still cold (frost expected tonight), should I be insulating to gain maximum use of the greenhouse at this time of year?
I have my own cement mixer and not afraid to use it!!

My advice is to bubble wrap, the fact that the sunlight gets diffused is a big help as it stop plants getting scortched when the sun is too bright.

I agree with 8doubles...insulate.

I do and then don't need shading in summer  :)

Bubble wrap imho does cut down the light significantly enough to affect the growth of seedlings in early spring.

Great insulation in winter, can provide shade in summer (if ventilation is possible) .... I only use it on part of the greenhouse and take it down as soon as the depths of the winter are over, then use it as a 'lay over' supported on upright kitchen roll tubes whenneeded over anything past then --- really really cold I also add fleece, but take it off agina each day when things have warmed up

My little 6x6 greenhouse is bubblewrapped all year.  My seeds have germinated well, albeit they took a little longer than the packets say.  Then when bigger, they go into the tunnel and bigger greenhouse.  

I'm lucky that way I suppose.

Then once the young plants have been moved, I will keep my indoor cucumbers in there.  I did have 6 tomatoes in it last year and they still did well.

The key there for me would be in moving the seedlings fairly soon after they come up, to somewhere brighter, so that they are not too leggy. (My greenhouse is not in full sun all day)

Again I'm lucky Sunny.  Our garden is south facing and gets sun almost all day.  My  tomatoes are still in there, are about 3 inches tall and lovely strong plants.

But you are right, it depends on people's personal situation doesn't it?  

Something I did the other year when my seeds were in the bigger greenhouse, was to fix up a coccoon on top of my staging with bubble wrap that had flaps at the front where I could get to my seedlings to water, and one man in a magazine article once had bubble wrapped the back half of his greenhouse so he could keep that bit warmer, then moved stuff to the sunnier cooler bit.

There are so many ways to keep stuff happy!   ;)

Which is why there is rarely a 'one-size-fits -all answer to questions asked  :D :D :D

My seedlings do perfectly well in my bubblewrapped greenhouse, no problems here ;)

In fact I would say there's more light inside the bubblewrapped glass house than there is inside the polycarb with the double layered roof.

The Polytunnel plastic also reduced light a little, but there was never a problem with seedling growth in there either.

 :lol: obviously you have to work with what light you have in the first place  ;)

warning! science bit - I think the wrap refracts light rather than reducing it  :blush:

I've only been away from the forum for a few hours and there are soooooooooo many useful replies. Thanks everyone.

So, if have read GrannieAnnnie's reply correctly, and my greenhouse is on an SW-NE axis, and I bubble wrap, I can move my tomato plants in now?

I'd actually wait a week if you possibly can - this week's forecast is for below average cold all week  ::)
