Greenhouse question

So if I pull the trigger and build a greenhouse heated by secondary radiant heat from my wood boiler and plant seedlings in 100 gallon pots late March, do I have to worry about flower/re-veg drama?
 
Most who put out their plants in March use some type of lighting to keep them in veg. I pop my seeds in April and never have any flower and reveg issues. Putting small plants in that large of a smartpot can cause root problems because it wont dry out fast enough. I bump my plants up in pot size about three times before they hit their final container,it gives them a larger root mass with less issues a long the way. Heating and cooling a greenhouse in my experience requires about 10 times the output as my house. Now is a good time to figure your electric needs and run a sub panel out to where you want to place your greenhouse. Those big dehumidifiers run some high electric loads. I would want some fans to blow air on my plants and others to move the air out of the greenhouse. Something with roll up sides with a screen will keep the fliers out that cause the worms. the only occasional problem that i run into is spider mites.
I nice distance from any thing that will cause shade on the south side is something you want to plan for. Good luck

Was planning on leaving things open mostly except temperature control with an outdoor wood boiler stove early and late in the season.
 
But yeah, could just huddle them in small pots near the heating pipes till they root out enough, just want that full sun exposure. This year it was solo cups to 2 gallon inside, to 65 gallon outside just after summer solstice.

Getaway mountain's greenhouse in Main looked like it had a wood pellet stove on one end. Load the hopper up a check on a daily bases. I'm not familiar with a wood boiler but if it is like my wood stove it needs feeding more than i would want to deal with.
 
Greenhouse would be secondary to my house hot water heat and you only have to load every 12 hours to keep it going.

where i am at solo cups elevated up off of those heat mats keep the roots warm enough,sitting on the mats causes problems. the first month I don't see much top growth i bet there wouldn't be much of a size difference if i planted a month later. How about starting yours indoors with the light cycle timed for a may put out when the weather is warmer
 
May is better then June 20 something this year lol. April here can be down to freezing easy and March way below zero(-20 lol). I'm clearing an acre of woods this fall though so wood for heat isn't a problem. But idk, just an idea i'm kicking around, nothing is in motion yet.
