When to move rockwool seedlings to dutch buckets

[gdgdad]

Well, I think I’ve completed the green house, and just in time (see pics). We’ve already had a night go down to 39F – very unusual for this area this time of year. Luckily the greenhouse was completely enclosed and the undersized heater I had was able to keep temp just barely above 50F. I have a new heater coming Thursday that’s actually listed as “suitable for agriculture”. Ideally, it should only run at night, so hopefully it won’t kill my electric bill. It has a thermostat so I was thinking keep it at 55 – your thoughts???
Even when we have a rare 55 or so degree day (for the high), the sun takes that greenhouse well into the 80’s by 9 or 10 am. You can see from the pics the plants appear to be doing well, there’s some flowering and I’ve “pollinated” via the electric tooth brush method. All these plants are from the seeds you sent me, so you’d know better how they’re doing. I’ve removed suckers and placed them in the rockwool cubes per the method you described and into the aeroponic cloner. Can’t believe they already produced roots – not sure what I’m going to do with them, keeping them as “back up” for now. I’ll be making my annual Christmas pilgrimage to Michigan ~ the 17th., and my neighbor (the farmer from Jamaica) is going to keep an eye on things. Pumps are on timers, heater is automatic, and the 55 gal reservoir level has barely moved so I think I’ll be alright. Still running nutrients at ~ 30% - think it’s time to increase that? Thanks again for all your help, hopefully I’ll be able to send you some winter tomatoes!!
