So far all seem to be going ok, but I have 2 plants with something on the leaves - not sure if it's due to my watering or something more serious - they've both been under growlights, with periodic times on the windowsill not under a light. Should I be concerned?

Don't think you have got anything to worry about, those plants look great , especially for this time of the yearOriginally posted by OakR View PostSo far all seem to be going ok, but I have 2 plants with something on the leaves - not sure if it's due to my watering or something more serious - they've both been under growlights, with periodic times on the windowsill not under a light.

Pretty much maximim sunshine but still only half what tomatoes need...
Today was cloudless from sunrise to sunset and my greenhouse is unobscured now the sun is over the hedge. Commercial growers seem to use light intensity of 20 mol photon day -1. Even with this sunshine I only managed 10.2 mol photon day -1 - half what they aim for. I suppose this will go up as the days lengthen.
In the graph the notches are when the sun is shaded by parts of the greenhouse frame. The sensor is a leaf level.
The plants themselves are doing fine. The Gardener's Delight are just forming flower buds.I live in a part of the UK with very mild winters. Please take this into account before thinking "if he is sowing those now...."

You gonna eat them mate, or do scientific experiments on them?!
Fascinating mind. But are you using some as a base, you know just plant them and let them get on with it? Gardeners Delight are pretty good, standard 'do-ers'

Not really an experiment: just trying to minimise chances of failure.Originally posted by smallblueplanet View Post

Toms are pretty hardy plants all told. How many are you growing, indoors or out?I live in a part of the UK with very mild winters. Please take this into account before thinking "if he is sowing those now...."

I've no idea what state the 20 or so tomato plants I left at the allotment 2 weeks ago are (though someone has been watering them very kindly), but the remainer I kept in the house appear to be doing well - gave them an outing in the blow-away greenhouse we put up today but brought them in for the evening. Hoping for some warmer weather soon. They have definitely grown faster than I expected (though I was warned), though the cucumbers have been the worst (or fastest) growers.
So far I'm pleased as a first year trial but time will tell - hey could still all end up in the compost heap but I hope not!

Tomatoes doing well and see big difference in last few week they have really shot up. Just started putting them in the gh during the day but will be a while before I would leave them overnight. Struck by the difference between the types I'm growing. Black icicle more straggly than shirley but remember the were like that last year, much more likely to wilt too. Fab tasting tomatoes though. Didn't start that early this year but happy with where they have got to. Got too many as usual but hopefully will be able to give some away.Last edited by annie8; 16-04-2020, 06:41 AM.
