Plant's

[Jondel]

I have got some small plug plants in the greenhouse, and I have got a parrafin heater which put on at night,

But i notice that some of the tops of the plants are going brown, can anyone tell me the reason for this.

I don't have a Greenhouse, but its possible that too much Oxygen is being sucked into it, if thats the case, then you have it too high, I've never used one, but flames feed on Oxygen, so its a possibility.

I think Lonnie could be right re your parrafin heater burnning off too much oxygen and possibly also fumes having an affect.

If you have nothing really tender in there you could try it without a heater. I have a cold green house and find no need for a heater, tempreture ranges from just above zerro to about 90+. I keep the door open during the day if its mild and sunny. Just a suggestion, Good Luck.
