Just putting them in a windowsill doesn't really get it. If you put them outside how hot is it? And of course it depends on what it is you are trying to grow. Some plants thrive in the heat and some don't.
Be careful with the micro greenhouse idea. Once the seeds are sprouted, you probably want to take the lid off, or at least prop it open some. It can easily get too damp in there, especially since the peat pots hold water a lot.
Starting this time of year, it's really just as easy to just plant your seeds in the containers outside.
I don't have a grow lamp or anything of that sort. It just so happens my Saltwater fish tank has 150watt metal halide. I could put it near there. It gets pretty hot here usually between 85-90 (outside). can they withstand that high of temp? I planted mostly peppers (different variety's. ), some cherry tomatoes and cilantro and basil.I noticed a lot of condensation on the greenhouse lid so I cracked it open slightly. Currently I have the two greeenhouses outside in a shady area of the back deck. I guess I'm worried that 90 degree summer temps might be too hot? My townhouse stays at about 68 on average. any help would be appreciated.
