Grow lights, heaters etc, on a budget

My grow light has a built in fan...is that sufficient would you say?

 

Excuse the senior moment! You could try taking them out of the box for a few days to see if they recover, or just try one. The only other thing I can think of is perhaps they need feeding. If they dry out very quickly that in turn means more watering and nutrients disappearing.

I have now John

 

If it doesn't feel hot to the back of your hand, and the same distance from the lights as the leaves are, then i doubt it is heat. (You need to leave your hand there for 30 seconds or more, you won't feel "Moderate" heat immediately)

Loli: Do they need some Epsom salts maybe? Unusual this early on ... but maybe Magnesium is missing from their diet.

 

Just like to thank everyone for their great information and helpful advice

 

So do you guys have heat mats under the plants as well as lights on top ? I have mine separate (although heat mat is next to one of my lights - but if I left plants there they would grow sideways) I assumed heat mat was for germinating and thereafter the lights do the job (although the begonias didn't fare so well coming off the heat so early) but everything else copes ok. I have only ever kept tomato plants under the lights to give them a boost before they go in the greenhouse - to clear room for other plants to go under the lights. I also spray all plants every so often with SB Plant Invigorator both as a boost and prevention for any bugs.

I'm using the base of a heated propagator in my 'grow box' for my tomatoes @sumbody

Got some blossom forming on my tomatoes

 

oooh - toms for Easter eh Loli?

@fat controller ....i'm sure once when i'd sown some Begonias it was a good 2wks before they showed ...so not long now

 

Put the seed tray / pot in a plastic bag? Evaporated water vapour will condense and thus trickle back to the pot, or re-evaporate to keep it 100% humid.

Or maybe you have a propagator / clear-plastic dome thingie? Is so that should be doing the same job. (No harm in misting the surface though, give them every encouragement
